Ordering pre-bent rebar makes sense on a big pour with a detailed bar schedule. On a footing, a retaining wall, a set of fence posts or a slab with a few dozen hooks and corners, bending it yourself on site is faster and cheaper. The right bender depends on three numbers: the largest bar you’ll bend, the angle you need, and how many bends you’ll make in a day. This guide compares 10 rebar benders on Amazon across three groups: electric hydraulic machines that bend 5/8-inch bar in a few seconds, a cordless option, and manual hand benders and cutter-benders that cost a fraction as much.

Rebar Sizes: #, Inches and Millimeters
In the US, rebar is sized by number, and the number is the diameter in eighths of an inch. #3 is 3/8 inch, #4 is 1/2 inch, #5 is 5/8 inch, #6 is 3/4 inch and #8 is 1 inch. Most Amazon benders also list a metric range, and that’s where listings get confusing. A 16 mm bar is roughly #5, 20 mm is roughly #6 and 25 mm is roughly #8.
Read the capacity carefully. One CENTALL listing in this guide says “#5” in the title and “#6-16 mm” in the bullet points. 16 mm and 5/8 inch are both #5, so #5 is the number to trust. Also check the grade. Most US structural rebar is grade 60, and a bender rated for “5/8 inch” mild steel round bar may struggle with grade 60 #5. Happybuy is one of the few listings here that names grade 60 directly.
| Bar Size | Diameter (in) | Approx. Metric | Common Use |
|---|---|---|---|
| #3 | 3/8″ | 10 mm | Slabs, ties, light walls |
| #4 | 1/2″ | 13 mm | Footings, slabs, block walls |
| #5 | 5/8″ | 16 mm | Footings, walls, columns |
| #6 | 3/4″ | 19-20 mm | Heavier walls and footings |
| #8 | 1″ | 25 mm | Columns, heavy foundations |
Manual vs. Electric Hydraulic vs. Cordless
A manual hand bender (often called a hickey bar) is a long steel handle with a head that hooks over the bar. You put your foot on the bar, or pin it to a bench, and pull. It’s the cheapest option, weighs a few pounds and never needs power. It’s fine for a handful of bends in #3 or #4 bar, and hard work once you get into #5.
A manual lever cutter-bender mounts to a board or bench and uses a long lever for more force. It’s slower than an electric machine but cuts as well as bends, and it doesn’t need a generator.
An electric hydraulic bender uses a motor to drive a hydraulic ram that pushes the bar around a roller. Press the switch, the ram moves forward and the bar bends in a few seconds. Release the switch at the angle you want, then open the relief valve to pull the ram back. If you’re bending dozens of #5 bars a day, it pays for itself in saved time and shoulders.
A cordless hydraulic bender does the same job without a cord, which helps on sites with no power yet. In this guide there’s only one, and it has very little buyer feedback.
Bend Angle: 90°, 130° and 180°
Check the maximum angle before you buy. Most handheld electric benders here go to 130 degrees, which covers 90-degree corners and most hooks. The VEVOR 1500W #6 model is limited to 0-90 degrees, so it can make L-bars and corners but not 135-degree tie hooks.
Full 180-degree hooks need either a dedicated 180-degree machine, which costs several thousand dollars, or a manual lever bender that’s rated for 180 degrees. If your drawings call for 180-degree hooks on #5 bar, confirm the angle rating before you order.
Bend Diameter and Field Bending Rules
A rebar bend isn’t just an angle. The bar wraps around a pin or roller, and the diameter of that pin controls how tight the bend is. ACI 318 sets minimum inside bend diameters for standard hooks and for stirrups and ties by bar size (ACI 318-19 Tables 25.3.1 and 25.3.2, summarized by ideCAD, retrieved 2026-10-15). Bending too tight can crack the bar on the outside of the bend. Your structural drawings or engineer set the required bend, so check the roller or pin size on a bender against them.
Two practical rules follow. Don’t heat rebar to make it bend easier unless the engineer has approved it, since heat changes the steel’s properties. And don’t bend bars that are already partly cast into concrete unless the drawings or engineer allow it.
Electric Hydraulic Rebar Benders
1. CENTALL HRB16 Electric Hydraulic Rebar Bender – Best Overall Electric
The HRB16 is the fastest #5 bender in this guide. CENTALL lists 2 to 2.5 seconds per bend for 5/8-inch bar, driven by a 1100W copper-wound motor and 13 tons of hydraulic force. It handles 1/4 to 5/8-inch (6-16 mm) rebar and bends from 0 to 130 degrees on a 110V, 60Hz supply.
The head has an eccentric wheel that you can turn 180 degrees to bend thinner bar, so one machine covers #2 through #5 without swapping parts. Operation is one switch: hold it to push the bending block forward, release at your angle, then pull the relief valve to return the piston. A rear grip and a front handle let you carry it or lift it into position. At 36.5 pounds it’s a two-hand carry but light enough to move around a footing. It holds 4.6 stars across 52 ratings, the best rating among the #5 electrics here.
Against the Happybuy below, the CENTALL bends in about half the time and has a stronger motor. The Happybuy has more buyer reviews and an adjustable stop bolt for repeat angles.
Pros: 2-2.5 second bends; 1100W motor and 13 tons; eccentric wheel for thinner bar; 0-130° range; best rating among the #5 electrics.
Cons: The listing mixes “#5” and “#6” in its sizing (it’s a #5 machine); 36.5 pounds is heavy for overhead work.
Skip it if: you only bend a few bars a year. A manual bender does that for a tenth of the price.
2. Happybuy 900W Electric Hydraulic Rebar Bender – Best Value Electric
Happybuy’s bender is the most-reviewed electric model in this guide, with 4.4 stars across 122 ratings. It bends up to #5 (5/8-inch) grade 60 rebar from 0 to 130 degrees in about 5 seconds, using a 900W copper-wound motor. The listing is one of the few that names grade 60, which is what most US structural rebar is.
The detachable positioning bolt is the useful extra. Set it once and every bend stops at the same angle, which matters when you’re making 40 identical L-bars for a footing. Two handles, a rear grip and a front handle, give you control while the ram is moving. Operation is the same hold-to-bend switch as the CENTALL.
Pros: Most buyer reviews of any electric bender here; rated for grade 60 #5; adjustable stop bolt for repeat bends; 0-130° range.
Cons: About twice as slow per bend as the CENTALL HRB16; smaller 900W motor; weight isn’t listed.
Skip it if: you need #6 or bigger. Look at the VEVOR models or the CENTALL HRB25.
3. CCTi RB-165A Portable Rebar Bender – Best Named-Brand Electric
The RB-165A is sold through the California Concrete Tool (CCTi) store, a named concrete-tool brand rather than a generic import label. It’s an electric hydraulic bender for #5 (5/8-inch) rebar and round bar, at 35.4 pounds.
The listing is short on detail. It doesn’t give the bend angle range or seconds per bend, so check those with the seller before you order if your job needs more than 90 degrees. It has 4.1 stars across 47 ratings, a little lower than the CENTALL and Happybuy.
The case for the CCTi is support. A named brand with its own product line is easier to reach for parts and warranty questions than a marketplace-only seller.
Pros: Named concrete-tool brand behind it; #5 rebar and round bar; 35.4 pounds, the lightest electric here with a listed weight.
Cons: Angle range and speed aren’t listed; lower rating than the CENTALL and Happybuy.
Skip it if: you want the most information up front. The CENTALL and Happybuy listings spell out angle and speed.
4. VEVOR 1.5 kW Handheld Hydraulic Rebar Bender – Best Wide-Range Electric
VEVOR lists this 1500W bender for bar from 0.2 to 1 inch (4 to 25 mm), the widest range of any handheld electric here, and says it bends within about 5 seconds. The angle can go past 90 degrees, though the listing doesn’t give a maximum.
A precision pressure relief valve releases the ram once the bend is done, and the motor only runs while you’re bending, which cuts wear and noise. It weighs 49 pounds. It holds 4.6 stars across 55 ratings.
A 1-inch capacity on a handheld machine is a big claim. If you plan to bend #8 bar regularly, the CENTALL HRB25, built specifically for 1-inch bar with 17 tons of force, is the safer pick.
Pros: Widest bar range here (4-25 mm); motor runs only while bending; strong 4.6-star rating.
Cons: Maximum angle not stated; 49 pounds; 1-inch claim on a handheld tool is worth verifying with the seller.
Skip it if: you need a guaranteed 130° bend. The CENTALL HRB16 and Happybuy both list it.
5. CENTALL HRB25 Electric Hydraulic Rebar Bender – Best for #8 (1-Inch) Rebar
The HRB25 is the big brother of the HRB16, built for columns and heavy footings. It bends rebar up to 1 inch (#8, 25 mm) in 3 to 4 seconds, with a 1200W copper-wound motor and 17 tons of force.
It keeps the same eccentric-wheel head as the HRB16, so you can turn the wheel to bend thinner bar on the same machine. The trade-off is weight: 50 pounds, which is a lot to hold at waist height through a day of bending. It has 4.5 stars across 22 ratings.
Pros: Built for 1-inch #8 rebar; 17 tons of force; 3-4 second bends; eccentric wheel for smaller bar.
Cons: 50 pounds; costs more than the #5 machines; fewer ratings than the HRB16.
Skip it if: your biggest bar is #5. The HRB16 is lighter, faster and cheaper.
6. VEVOR 1500W Electric Hydraulic Rebar Bender (#6) – Best Kit with Metal Case
This newer VEVOR model bends 6 to 20 mm bar, up to 3/4-inch #6, in 4 to 5 seconds with a 1500W copper-wound motor. It ships in a metal toolbox that holds the machine and its tools, useful if it rides in a truck bed between jobs.
The important limit is the angle. VEVOR lists an adjustable range of 0 to 90 degrees, not 130. That covers corners and L-bars but not 135-degree tie hooks. It weighs 44.1 pounds and has 4.7 stars, but from only 7 ratings.
Pros: #6 capacity; 1500W motor; metal storage case included; high early rating.
Cons: Bends only to 90°; very few ratings so far; 44.1 pounds.
Skip it if: you need hooks past 90°. The CENTALL HRB16 or Happybuy go to 130°.
Cordless Rebar Bender
7. LOSCHEN Cordless Rebar Bender – The Only Cordless Option
On a site where the power isn’t on yet, a cord means a generator. The LOSCHEN runs on a lithium battery, and the battery and charger are included. LOSCHEN lists bending up to 3/4-inch (20 mm, #6) bar from 0 to 130 degrees, with a body made of what it calls space aluminum.
It’s in this guide because it’s the only cordless rebar bender we found on Amazon, not because it has a track record. It has 3.7 stars from only 3 ratings, and it’s the most expensive handheld bender here. The listing also lists “Electric Rebar Cutter” as the included component, which looks like a listing error, so confirm what’s in the box.
Pros: No cord or generator needed; battery and charger included; #6 capacity; 0-130°.
Cons: Weak, thin rating record; highest price of the handheld benders; 46.9 pounds; confusing box contents on the listing.
Skip it if: you have power on site. A corded CENTALL or Happybuy is cheaper and better proven.
Manual Rebar Benders
8. Crescent H.K. Porter RB6 Indexing Rebar Bender – Best Manual Hand Bender
H.K. Porter hand tools are now sold under the Crescent name. The RB6 bends 3/4-inch (#6) bar, more than the typical 5/8-inch hand bender. The feature that sets it apart is the 14-position indexing head. A center push-button lets you rotate the head to a new position, so you can keep the handle at the best angle for leverage as the bend progresses (Crescent, retrieved 2026-10-15).
Crescent lists an overall length of 44.25 inches with a 38-inch handle, chrome-vanadium steel construction, laser-etched markings and a full lifetime warranty. The Amazon listing weight is 8.9 pounds. It holds 4.1 stars across 60 ratings.
The longer handle is where the extra capacity comes from. More length means more leverage, but you’ll also need more room to swing it.
Pros: #6 capacity in a hand bender; 14-position indexing head; chrome-vanadium steel; full lifetime warranty.
Cons: 44-inch length needs room to work; #6 bar by hand is still hard physical work; costs several times more than the MARSHALLTOWN.
Skip it if: you only bend #3 and #4. The MARSHALLTOWN QLT handles those for much less.
9. MARSHALLTOWN QLT 34-Inch Manual Rebar Bender – Best Budget
For a homeowner setting a few fence-post footings or a contractor who needs a bender in the truck for the occasional hook, the MARSHALLTOWN QLT is the simple answer. It’s a 34-inch hickey bar rated for rebar up to 5/8 inch, from MARSHALLTOWN’s contractor-grade QLT line, and it weighs 5 pounds.
It has 4.1 stars across 141 ratings, the most of any rebar bender in this guide. Bending is freehand: no angle marks or indexing head, so you judge the angle by eye or against a template. A 5/8-inch bar on a 34-inch handle takes real effort, and #3 and #4 are where it’s comfortable.
The Tondiamo 34-inch manual bender (B0CWLG9PM1) is a near-identical alternative, rated for 5/8-inch bar with 4.3 stars from 50 ratings.
Pros: Lowest price here; most-reviewed bender in this guide; 5 pounds; contractor-grade QLT brand.
Cons: No angle marks; 5/8-inch bar is hard work at 34 inches; one size head for all bars.
Skip it if: you’re bending more than a dozen bars at a time. Your shoulders will want an electric bender.
10. Threlaco Rebar Bender & Cutter – Best Manual Cutter and Bender
Most jobs need bars cut to length as well as bent. The Threlaco does both on one mounted machine, for rebar up to 5/8 inch. It bolts to a surface and uses a long lever with a non-slip grip, so your body weight does the work instead of your arms.
At 43.9 pounds it isn’t portable the way a hickey bar is. It’s a bench or trailer tool. It costs far less than an electric bender plus a separate electric cutter. It has 4.2 stars across 21 ratings.
LOSCHEN sells a similar manual cutter-bender on a wooden board (B0H55356F5) that lists a 0 to 180-degree bend range for #5 bar. It has 4.8 stars, but from only 6 ratings.
Pros: Cuts and bends on one tool; no power needed; long lever reduces effort; mounts to a bench or board.
Cons: 43.9 pounds, so it stays put; slower than an electric bender; angle range not listed.
Skip it if: you already own a rebar cutter. A hand bender or electric bender is the better spend.
Pair It With: Cutting and Tying Tools
A bender is one step. Rebar also has to be cut to length and tied into a cage.
For cutting, a dedicated electric rebar cutter shears bar cleanly in seconds without sparks. An angle grinder with a cut-off wheel works for occasional cuts but throws sparks and is slower. A reciprocating saw with a metal blade is another option if you already own one.
For tying, Klein Tools D248-9ST ironworker’s pliers are the standard hand tool, with 4.8 stars across 6,218 ratings. If you’re tying a large slab, an automatic rebar tier speeds the job up a lot.
Buying Guide
Bar Capacity and Grade
Buy for the largest bar on your drawings, and check that the rating is for grade 60 if that’s what you’re bending. A machine rated “5/8 inch” without a grade may be rated for softer round bar.
Force and Speed
Tonnage tells you how much push the ram has. The 13-ton HRB16 bends #5 in 2-2.5 seconds. The 17-ton HRB25 handles #8. More tons means you’re less likely to stall on a hard bar.
Angle Range and Repeat Stops
130 degrees covers most hooks. 90 degrees covers only corners and L-bars. An adjustable stop bolt, like the Happybuy’s, lets you repeat the same angle without measuring each bar.
Power
The corded electrics here run on 110-120V. Check that your generator or site panel can handle the motor’s start-up load. A cordless bender removes that question but costs more.
Weight and Portability
Electric handheld benders here weigh 35 to 50 pounds. If you’ll bend at waist height for hours, the lighter #5 machines are easier on your back. Manual hand benders weigh 5 to 9 pounds.
Safety
Keep your hands clear of the bending head and roller when the ram is moving. Bars can spring back or slip, so wear safety glasses and heavy work gloves, and put rebar caps on exposed bar ends. Open the relief valve and let the ram retract before you pull the bar out.
Frequently Asked Questions
Can I bend rebar by hand without a tool?
Small #3 bar can be bent around a pipe or post, but it’s hard to get an accurate angle and you risk kinking the bar. A $35 hand bender gives you leverage and a cleaner bend.
Can I heat rebar to make it easier to bend?
Not without approval from the engineer. Heat changes the steel’s properties. Cold bending with the right tool is the normal approach.
Can a 5/8-inch bender handle #6 rebar?
No. #6 is 3/4 inch. Running bigger bar than the rating strains the hydraulics or the handle and can give a poor bend. Buy for your largest bar.
Can I re-bend or straighten rebar?
Re-bending the same spot weakens the bar and can crack it. Bending bars already partly cast into concrete is restricted under ACI 318 unless the drawings or engineer allow it. If a bend is wrong, cut a new bar.
Do electric rebar benders also cut?
The handheld electric benders here only bend. Some combination machines cut and bend, like the manual Threlaco in this guide. Otherwise, use a separate rebar cutter.
What’s the difference between a rebar bender and a hickey bar?
“Hickey” is the trade name for a manual hand bender: a long handle with a hooked head. The MARSHALLTOWN QLT and Crescent H.K. Porter RB6 are both hickey-style benders.
