Correction notice: An earlier version of this article described “our torque testing” even though no FlawCheck test protocol, samples, measurements, or test record existed. That language was unsupported and has been removed. The page will remain excluded from search indexing until the Makita model identity is confirmed and the comparison can be rebuilt from reliable evidence.
The most dangerous tool comparison is not one with a close result. It is one that compares a documented product with a model name that may have been copied, mistranslated, announced for another market, or confused with a nearby model.
That is the problem with DEWALT DCD791 vs Makita XFD17 today. DEWALT documentation supports the basic identity of the DCD791. FlawCheck could not verify an official Makita USA product page for the exact XFD17 designation as of August 27, 2026. Without that page, a neat specification table would create confidence that the evidence does not deserve.
What we can verify about the DEWALT DCD791
The DCD791 belongs to DEWALT’s 20V MAX XR compact drill/driver family. Manufacturer support material and the instruction manual establish that it is a conventional drill/driver rather than a hammer drill. DEWALT also publishes recommended drilling capacities for the model.
The practical implications are more important than the badge:
- It is intended for drilling and controlled screwdriving in materials such as wood, metal and plastic.
- It uses a two-speed transmission and a 1/2-inch keyless chuck.
- It does not add the percussion mechanism needed for efficient masonry drilling.
- It is an older model, so the purchase case depends heavily on clearance price, battery bundle and warranty status.
The last point is the hidden downside. An older professional tool can still be useful, but “XR” does not automatically make an old kit a good deal. A bare tool is cheap only if you already own compatible batteries and a charger. A used kit is attractive only if the battery health is known.
Why the XFD17 side cannot be scored normally
Makita model numbers are market-specific, and visually similar tools can have different designations, torque ratings, transmissions or kit contents. Retail listings and videos may also surface before a stable official product page appears.
Until the exact XFD17 identity is verified, we cannot responsibly claim:
- Its official no-load speeds.
- Its weight with or without a battery.
- Its maximum torque under Makita’s stated test method.
- Whether it is a drill/driver, installation driver or another format.
- Which battery and charger are included.
- Whether a U.S. warranty applies.
- Whether an apparently equivalent international model is mechanically identical.
This does not prove that the tool is poor or unreal. It means the available evidence is insufficient for a high-confidence purchase recommendation.
The specification-table trap
Cordless drill comparisons often place voltage, torque, RPM and weight in four rows and announce a winner. That method hides several problems.
“20V MAX” and “18V” are not a simple power ranking
DEWALT’s 20V MAX branding refers to maximum initial battery voltage; nominal voltage is 18V. It should not be interpreted as an automatic advantage over Makita’s 18V LXT platform.
Torque numbers may use different methods
Manufacturers may publish hard torque, soft torque, stall torque or output measures that are not directly comparable. A larger number does not guarantee faster drilling across bit sizes and materials.
Tool weight is meaningless without battery context
A bare-tool figure cannot be fairly compared with a weight that includes a 2.0Ah or 5.0Ah battery. The pack can materially change balance, fatigue and overall mass.
Kit suffixes change the value
The last letters and numbers may identify a bare tool, battery capacity, charger or case. Two listings with the same drill body can represent very different ownership costs.
Which tool should you choose today?
Choose the DCD791 only if:
- You already own compatible DEWALT batteries.
- You need a standard compact drill/driver, not a hammer drill.
- The price reflects its age.
- The seller clearly states the exact suffix and kit contents.
- Warranty or return protection is adequate.
Do not choose an “XFD17” listing yet unless:
- The seller links to an official Makita page or manual for the same market.
- The nameplate and model suffix are visible.
- Battery, charger voltage and warranty region are confirmed.
- The return policy protects you if the listing is inaccurate.
If neither seller can provide those details, buy a currently documented model instead. A slightly less exciting tool with a verifiable manual, parts path and warranty is the safer professional purchase.
The battery ecosystem is the real tie-breaker
For most cordless-tool buyers, platform cost outweighs small specification differences. Ask:
- Which compatible batteries do you already own?
- What will a second useful-capacity battery cost?
- Can the charger be used on your local voltage?
- Are repair parts and service available in your region?
- Does the kit include a case, belt hook and charger?
- Is the battery new, old stock or used?
Switching platforms for one drill can turn a small sale discount into a larger long-term expense.
Final recommendation
There is no defensible performance winner yet.
The DEWALT DCD791 is the lower-risk documented option for existing DEWALT battery owners when priced appropriately. Its disadvantages are age, lack of hammer mode and the possibility that a newer compact drill offers better size-to-output performance.
The Makita XFD17 should remain a wait until its exact official identity is verified. A low evidence-adjusted score is not a judgment that the hardware is bad; it is a warning that buying confidence is bad.
FlawCheck will remove the temporary noindex status and rescore this comparison only after official Makita documentation for the exact model is available.
Sources and methodology
DEWALT’s support library provides the DCD791 instruction manual, and DEWALT separately publishes recommended drilling capacities for the DCD791. Battery voltage terminology should be read with DEWALT’s statement that 20V MAX is maximum initial voltage and nominal voltage is 18V.
