DEWALT DCK250QQ2 20V MAX XR Hammer Drill and Impact Driver Kit

Wood, metal and light masonry work on 4Ah POWERPACK batteries

This kit pairs DEWALT's DCD806 two-speed hammer drill with the three-speed DCF845 impact driver and two 4Ah POWERPACK batteries. The drill's manual caps carbide masonry bits at 1/4 in., so it is aimed at pilot and anchor holes rather than large concrete work. The kit page lacked warranty text when read.

Two XR brushless tools and two 4Ah POWERPACK batteries

DEWALT's kit page lists a DCD806 20V MAX XR brushless 1/2 in. hammer drill, a DCF845 20V MAX XR three-speed 1/4 in. impact driver, two DCB2104 XR POWERPACK 4Ah batteries, one charger, two belt hooks and a contractor bag. The charger model is not named on the kit page or in the Amazon details, so check it on the box if charging speed matters to you.

DEWALT gives the assembled kit as 10.67 lb and eight pieces, with dimensions of 14.88 by 9.25 by 5.56 in. Amazon's table says 10.65 lb, which is effectively the same weight.

The drill: two speeds, fourteen clutch settings and a hammer mode

The DCD806B page lists two speed ranges of 0 to 650 and 0 to 2,000 rpm, a 1/2 in. chuck, fourteen clutch settings and a three-position LED rated at 70 lumens. The manual adds drill and hammerdrill positions on the mode collar beyond the 1 to 14 clutch settings, and says the clutch is not active in drill or hammer mode.

DEWALT's own claims of being up to 109 percent more powerful and up to 175 holes per charge are measured against a DEWALT DCD778 or with a 7/8 in. auger in 1-1/2 in. SPF, per its footnotes. The same spec table also shows a no-load speed entry of 34,000 rpm, which does not match the 2,000 rpm stated in the page's own features, so rely on the 650 and 2,000 figures.

Masonry capacity is small: check the 1/4 in limit before buying

The DCD801/DCD806 manual's maximum recommended capacity table lists carbide masonry bits up to 1/4 in. for the DCD806. Wood capacities are 1-1/2 in. for auger and paddle bits, 1 in. twist, 2-9/16 in. self-feed and 3 in. hole saws; metal is 1/2 in. twist and 1-1/2 in. hole saw. Anyone planning larger anchor holes in concrete should read that line first.

The manual lists an ANTI-ROTATION system with a red indicator light. For hammerdrilling technique and bit selection, follow the manual's operation pages; this guide records the capacity table and the mode collar, not the drilling procedure.

The impact driver takes hex impact bits only

DEWALT rates the DCF845 at 1,825 in-lbs of torque and 3,400 rpm with three speed settings; its footnote says the thirty percent more torque claim is against the DCF885 rated at 1,400 in-lbs. The tool page lists 8.07 in. length and 2.35 lb without a battery. The chuck takes 1/4 in. hex accessories and 1 in. bit tips only.

The DCF845 manual says to use only impact-rated accessories, and to check critical fastenings with a torque wrench because delivered torque varies. Its worklight turns off twenty seconds after the trigger is released.

Charging and cleaning routine from the manuals

The drill manual says to charge only when air temperature is between 40°F and 104°F, and recommends 65°F to 75°F for the longest battery life. A hot or cold pack triggers a delay on the charger, and charging resumes on its own once the pack is at temperature.

The drill manual asks you to blow dust out of the vents at least once a week. Both manuals say chargers and batteries have no serviceable parts. The charger manual and the combined impact-driver manual NB405943 were not read for this guide.

Warranty: the kit page is blank, the tool pages and manuals are not

When read, the DCK250QQ2 kit page said warranty information was currently unavailable. The DCD806B and DCF845B tool pages both list a three-year limited warranty, one year of free service and ninety days of satisfaction guarantee, and both manuals carry a three-year limited warranty heading.

The manuals state that this warranty does not apply to products sold in Latin America. Because the kit page itself is blank, confirm coverage with DEWALT or on the packaging for the exact kit you receive, and keep the purchase record.
