A contractor-grade hammer drill has to do two things a homeowner model doesn't: survive a battery platform you've already invested thousands of dollars into, and keep working after a year of being thrown in the truck bed. We compared five current picks on torque, weight, platform and warranty.
| Model | Platform | Torque | Weight | Best for |
|---|---|---|---|---|
| Milwaukee M18 FUEL 2997-22 | M18 (18V) | 1,200 in-lbs | 3.9 lbs | Best overall combo kit |
| DeWalt 20V MAX XR DCD996P2 | 20V MAX | ~820 in-lbs | 4.4 lbs | Proven, serviceable workhorse |
| DeWalt FlexVolt DCD999 | 20V/60V | 1,250 in-lbs | 4.7 lbs | Heaviest fastening & masonry work |
| Makita GPH03 (2026) | 40V XGT | 1,300+ in-lbs | 4.1 lbs | Most power, newest platform |
| Makita XPH14 | 18V LXT | ~1,090 in-lbs | 3.4 lbs | Lightest, most predictable handling |
Torque and weight figures are drawn from manufacturer specifications and the trade comparisons cited below; DeWalt's XR figure is an approximate conversion where the manufacturer lists UWO rather than peak torque. Confirm current specs before buying — manufacturers revise lineups without much notice.
Our picks
Best overall
Milwaukee M18 FUEL 2997-22
Hammer drill + impact driver combo kit · M18 platform
If you're starting a platform from scratch, this is the combo most trade reviewers keep coming back to: a brushless hammer drill paired with Milwaukee's impact driver, both drawing from the same M18 battery line that already covers most of Milwaukee's other tools. At 1,200 in-lbs of torque and 3.9 lbs, it's strong enough for structural fastening without being the heaviest drill in the bag.
- One of the largest cordless tool ecosystems to grow into
- Strong torque-to-weight ratio for all-day use
- Combo kit covers drilling and fastening in one purchase
- M18 batteries cost more than off-brand alternatives
- Not the single highest-torque option on this list
Proven workhorse
DeWalt 20V MAX XR DCD996P2
Brushless hammer drill · 20V MAX platform
DeWalt's XR line has been a jobsite standard long enough that parts, chargers and service are easy to find in almost any market. It won't out-torque the newer 40V-class tools here, but if your crew is already on 20V MAX, it's a known quantity that's hard to go wrong with.
- Widest third-party parts and service support
- Compatible with DeWalt's largest battery ecosystem
- Lower torque than the FlexVolt and XGT options below
Heaviest-duty fastening
DeWalt FlexVolt DCD999
Brushless hammer drill · 20V/60V FlexVolt platform
FlexVolt batteries automatically switch voltage depending on the tool, so the same pack runs this drill at a higher output than standard 20V MAX tools. At roughly 1,250 in-lbs it's built for repetitive structural fastening and masonry work where a standard drill will bog down.
- Highest sustained torque of DeWalt's current lineup
- FlexVolt batteries also run DeWalt's larger 60V tools
- Heaviest drill on this list at 4.7 lbs
- FlexVolt batteries carry a price premium
Most power, newest platform
Makita GPH03
Brushless hammer driver-drill · 40V XGT platform
Makita's 2026 flagship leads this list on raw output, built on the 40V XGT platform the company has been expanding for its highest-demand tools. It's the strongest option here, but XGT is the newest of the platforms compared and has fewer tools and accessories than the more established lines.
- Highest torque figure in this comparison
- 40V XGT reduces the number of batteries needed for high-draw tools
- Smaller accessory and tool ecosystem than 18V LXT or M18
- Newer platform means less long-term track record
Lightest & most predictable
Makita XPH14
Brushless hammer drill · 18V LXT platform
Not every job needs maximum torque. At 3.4 lbs, the XPH14 is the lightest drill on this list, and reviewers consistently point to Makita's LXT line for consistent, predictable handling over a long day of overhead or repetitive work — the kind of thing that matters more than peak spec once you're six hours into a shift.
- Lightest drill in this comparison
- LXT is Makita's largest and most mature battery platform
- Lower torque ceiling than the FlexVolt or XGT options
How to choose between them
Torque matters most if your work is heavy fastening or masonry drilling — that's where the FlexVolt and XGT options earn their weight. For general contracting and finish work, the lighter LXT and M18 options are easier on your wrist over a full day. The decision that matters more than any single spec, though, is which battery platform you're already invested in: switching platforms later means replacing every battery and charger, not just the drill.
If you're starting from zero, M18 and 20V MAX currently have the widest range of other tools built on the same batteries, which is worth more over time than a torque advantage on one tool.
