When it comes to power tools, DeWalt has long been a name synonymous with reliability and performance. The latest addition to their impressive lineup, the DeWalt 20V Max XR Brushless Impact Driver (DCF845), is here to further solidify their reputation. In this comprehensive review, we’ll delve into the details, performance statistics, and key features of this tool. So, if you’re in the market for an impact driver that delivers top-notch performance, stay with us as we explore what the DCF845 has to offer.
Performance Stats
Before we jump into the nitty-gritty details, let’s start by looking at the performance statistics of DeWalt’s three main impact drivers. All three of these models use brushless motors, ensuring efficiency and durability. Here’s a quick comparison:
20V Max XR (DCF845)
- Top Speeds: 1500/2800/3400 RPM
- Max Impact Rate: 4200 IPM
- Max Torque: 1825 in-lbs
20V Max Atomic (DCF850)
- Top Speeds: 1000/2800/3250 RPM
- Max Impact Rate: 3600 IPM
- Max Torque: 1825 in-lbs
20V Max XR (DCF887)
- Top Speeds: 1000/2800/3250 RPM
- Max Impact Rate: 3600 IPM
- Max Torque: 1825 in-lbs
At first glance, it’s evident that the DCF845 boasts faster driving speeds compared to the other models. DeWalt has made an interesting choice by not chasing higher torque numbers, and here’s why that matters. High-torque impact drivers can put excessive stress on the socket adapter, potentially causing breakage, especially with heavier loads. By maintaining the torque at 1825 in-lbs, DeWalt is encouraging users to consider an impact wrench for heavier applications, a smart and practical approach.
But, you might be wondering, how does all this data translate to real-world performance?
- BRUSHLESS MOTOR delivers 1,825 in-lbs of torque and 3,400 RPM to drive large diameter screws
- COMPLETE TOUGH FASTENING APPLICATIONS on the jobsite with 30% more torque****
- PRO-LEVEL CONTROL and precision with variable speed trigger and 3-speed setting
- BRIGHTEN DARK WORK AREAS with an integrated 3-LED work light for ehnanced visibility in low-light areas
Test Results
We rigorously tested the DeWalt 20V Max XR Brushless Impact Driver (DCF845) in three primary scenarios, using a standard 5.0Ah battery. These tests provide valuable insights into the tool’s practical performance:
- Driving an 8-inch x 1/4-inch GRK Fasteners RSS screw into stacked OSB subfloor: The DCF845 completed this task in just 9.1 seconds, showcasing its efficiency.
- Driving a 10-inch x 1/2-inch lag screw into stacked OSB subfloor: The DCF845 excelled here as well, with a result of 3.1 inches, indicating precision and power.
- Nut-busting test at 150 ft-lbs (1800 inch-lbs): Breaking loose a stubborn nut is where the DCF845 truly shines, taking only 5.4 seconds to complete the task.
Comparing these results to the other models, it’s clear that the DCF845 consistently outperforms its counterparts in all three tests. Even with the same torque rating, the higher top speed and impact rate make a significant difference in real-world applications.
Size and Weight
The form factor of the DCF845 closely resembles that of the DCF887, with only slight differences in length and weight. Here’s a quick comparison:
| 20V Max XR DCF845 |
20V Max Atomic DCF850 |
20V Max XR DCF887 |
|
| Top Speeds | 1500/2800/3400 RPM | 1000/2800/3250 RPM | 1000/2800/3250 RPM |
| Max Impact Rate | 4200 IPM | 3600 IPM | 3600 IPM |
| Max Torque | 1825 in-lbs | 1825 in-lbs | 1825 in-lbs |
The DCF845 strikes a balance between compactness and power, making it a versatile choice for various applications. Its lightweight and ergonomic design ensure that you can work comfortably for extended periods.
