A $500 saw with a garbage blade cuts like a $50 tool. A $100 saw with a premium blade cuts like a workshop staple.
If you’re fighting the saw, burning the wood, or watching your battery die halfway through a rip, it’s not the saw’s fault—it’s the piece of steel you bolted to it.

Buying Guide: The Technical Details
Before you buy, you need to know what you’re looking at. Don’t just grab the cheapest pack on the shelf.
1. Cordless vs. Corded: Which Blade Do You Need?
Here is the rule of thumb: Cordless saws benefit significantly from ultra-thin kerf blades. Because they remove less material, they reduce drag on the motor, which saves your battery life.
If you are running a 15-amp corded worm-drive, you can handle full kerf blades for better stability during heavy ripping, but on a battery tool, thick steel just kills your runtime.
2. Anatomy of a Cut
- Thin Kerf (~0.059″ / 1.5mm): Mandatory for 18V/Cordless saws.
- Full Kerf (~0.098″ / 2.5mm): Best for corded powerhouses where plate stability matters more than resistance.
Arbor Size (Don’t Screw This Up):
Pro Tip: Never force a blade onto a mismatched arbor. If it wobbles at 5,000 RPM, you’re asking for shattered carbide.
| Arbor Type | EU Equiv. | Adapter? | RPM / Usage Note |
|---|---|---|---|
| 5/8″ (15.9mm) | 20mm or 30mm | Yes (~$5 Ring) | Standard for US Wood Saws (5,000+ RPM) |
| Diamond Knockout | 16mm bore | Included | Worm Drive Saws (High Torque) |
| 1″ (25.4mm) | 30mm | Yes | Table Saws / Old Stationary Tools |
3. Tooth Count (Often Mistakenly Called TPI)
- 24T (Ripping): Fast and aggressive. Clears dust quickly but leaves a rough edge.
- 40T (General): The balance. Good enough for crosscuts, fast enough for ripping.
- 60T (Carbide): Fine Finish. Use this for plywood or veneers, not for framing 2x4s.
4. Hook Angle & Geometry
- High Hook (20°+): Grabs the wood aggressively (“self-feeding”). Ideal for ripping framing lumber.
- Low/Negative Hook (5° to -5°): Requires you to push the saw. Gives control and prevents chip-out on delicate plywood or metal.
🚩 Red Flags: How to Spot a Garbage Blade
- Uniform Teeth: If every tooth looks identical (no “zigzag” ATB pattern), walk away.
- No Carbide: Stamped steel dulls in minutes. If it doesn’t have welded carbide tips, it’s trash.
- Suspiciously Cheap: 3 blades for $10 = wobble city.
Comparison Table: At a Glance

|---|---|---|---|---|---|---|
| Diablo D0740A | 7-1/4″ | 40T | Thin | 10,000 Max | General / Everyday | $$ |
| DeWalt Elite | 7-1/4″ | 24T | Med | 7,000+ | Framing / Demo | $ |
| Diablo D0760A | 7-1/4″ | 60T | Thin | 10,000 Max | Plywood / Finish | $$$ |

Maintenance & Safety: Don’t Be an Idiot
- Forcing High-Tooth Count on Rips: If you try to rip a 2×4 with a 60T blade, you aren’t cutting; you’re burning the wood.
- Ignoring Expansion Slots: Cheap blades without these warp when they get hot. Look for the laser-cut squiggles—they let the metal expand without destroying your cut accuracy.
- Wrong RPM: Don’t put a wood blade (high RPM) on a metal saw (low RPM), or vice versa. Metal chips are sharp; saw dust is just annoying.
- Pitch Buildup: If your blade feels dull, check for pitch (resin) buildup first. It increases friction and heat. Clean it before you toss it.
Detailed Product Reviews
1. Best Overall: Freud Diablo D0740A (40T)
Price: ~$18 | Rating: ⭐⭐⭐⭐⭐ (4.8/5)
The Verdict: This is the blade to keep on your saw 90% of the time. The laser-cut stabilizer vents actually work to reduce vibration, and the TiCo Hi-Density carbide stays sharp longer than standard carbide.
- ✅ Pros: Thin kerf reduces load on the saw motor.
- ✅ Cuts clean enough for trim, fast enough for 2x4s.
- ✅ Perma-Shield coating prevents pitch buildup.
- ❌ Cons: Not aggressive enough for ripping thick hardwoods.
- ❌ Can flutter slightly on older, wobbly saws.
The Real World Test: We used this for a full deck rebuild. It handled the pressure-treated framing cuts with ease and then delivered splinter-free crosscuts on the composite decking boards without needing a blade swap.
2. Best for Framing: DeWalt Elite Series (24T)
Price: ~$25 (3-Pack) | Rating: ⭐⭐⭐⭐½ (4.6/5)
The Verdict: A total workhorse. The “WeldTec” bond prevents teeth from ripping off when you inevitably hit a nail.
- ✅ Pros: Extremely durable against nail strikes.
- ✅ “ToughTrack” technology keeps lines straight.
- ✅ Excellent value when bought in multipacks.
- ❌ Cons: Leaves a rougher edge (expect tear-out).
- ❌ Louder cutting noise than the Diablo.
The Real World Test: Designed for speed, not beauty. On a demolition job, this blade chewed through old studs with embedded nails and kept cutting for two more days.
3. Best for Plywood: Diablo D0760A Ultra Finish (60T)
Price: ~$22 | Rating: ⭐⭐⭐⭐⭐ (4.8/5)
The Verdict: The Hi-ATB geometry slices wood fibers like a scalpel. You get zero tear-out on birch plywood.
- ✅ Pros: Glass-smooth finish on veneers and melamine.
- ✅ Minimal sanding required after the cut.
- ❌ Cons: Slow feed rate required (don’t rush it).
- ❌ Will burn quickly if used for ripping.
Note: If you are cutting expensive cabinet-grade plywood, this $20 investment saves you from ruining $100 sheets.
4. Best for Cordless: Makita B-61656 6-1/2″ Thin Kerf
Price: ~$16 | Rating: ⭐⭐⭐⭐⭐ (4.8/5)
The Verdict: Designed specifically for lower RPMs and battery efficiency.
- ✅ Pros: 0.059″ kerf increases cuts-per-charge by ~30%.
- ✅ Less strain on smaller 18V motors.
- ❌ Cons: Thin plate can deflect if you push laterally.
- ❌ Specific to 6-1/2″ saws (check your size!).
The Real World Test: In our runtime test on a Makita LXT saw, this blade delivered 25 more cuts through 2x4s on a single 5.0Ah battery compared to a standard framing blade.
5. Best for Metal: Irwin Metal Cutting (30T)
Price: ~$24 | Rating: ⭐⭐⭐⭐ (4.3/5)
The Verdict: Cold-cutting technology allows you to cut unistrut and threaded rod without a shower of sparks.
- ✅ Pros: Cuts “cold” (burr-free edges).
- ✅ Safer than abrasive discs (no shattering risk).
- ❌ Cons: RPM Limit: Must be used carefully on high-speed saws.
- ❌ Loud operation on hollow metal.
⚠️ Safety Note: Always confirm the blade’s RPM rating exceeds your saw’s maximum RPM. Wear full eye protection—metal chips are sharp shrapnel, not dust.

Enhanced FAQ
Do circular saw blades fit all saws?
No. You must check three things: (1) Diameter (7-1/4″ vs 6-1/2″), (2) Arbor hole size (5/8″ is standard in US, 20mm in EU), and (3) RPM rating—cordless saws often spin slower than corded, and metal saws spin much slower.
When is the best time to buy circular saw blades?
Prime Day (July) and Black Friday often see prices drop 30-40% on multipacks from Diablo and DeWalt. If you’re not in a rush, set a price alert on CamelCamelCamel.
What blade should I use for pressure-treated lumber?
Use a 24T Framing Blade with a non-stick coating (like Diablo’s Perma-Shield). Pressure-treated wood is wet and sticky; coatings prevent pitch buildup that causes overheating.
Can I use a trim blade (60T) on framing cuts?
Avoid this. High tooth-count blades cut slowly and struggle to eject the large chips created by 2×4 ripping. You will likely burn the wood and dull the blade prematurely.
What does ATB mean on a saw blade?
ATB stands for “Alternate Top Bevel.” The teeth are angled left-right-left-right, creating a clean slicing action. This is the most common grind for crosscutting. The alternative is FTG (Flat Top Grind), which is better for ripping.
The Bottom Line
The right blade transforms your saw from frustrating to reliable. Don’t let a $10 blade ruin $100 worth of plywood.
Our Final Recommendation: If you only buy one thing today, grab the [Diablo D0740A 40T]. It’s the blade we keep on our jobsite saws 300 days a year because it just works.
