Prices include shipping and are refreshed daily. Availability changes without notice.

DCD999 covers more than one configuration. DeWalt uses it as a family number — sellers list both the bare tool and the kit with batteries under it, and the part number alone does not say which. The figures above span both, so the range is wider than for a single configuration. Check each listing's title for what is actually included.

Listings for a used DeWalt 20V MAX 1/2" Hammer Drill (DCD999) that have ended stayed live for a median of 6 days. A listing ending is not proof it sold — sellers also end listings unsold, and eBay relists some automatically.
Is it worth buying a DeWalt 20V MAX 1/2" Hammer Drill (DCD999) used instead of new?
A used DeWalt 20V MAX 1/2" Hammer Drill (DCD999) asks about 50% of what the same tool costs new on eBay — $116.25 used against the new median. That is a substantial saving, and it is the kind of gap where buying used usually makes sense.

Half of the 16 live listings sit within a $33 window, $106.66 to $139.90. The tightest $20 window holds 6 of 16, $99 to $117. 9 of 16 (56%) are asking under $120.

What should I sell my used DeWalt 20V MAX 1/2" Hammer Drill (DCD999) for?
Price it around $116.25 to sit mid-market, or at or below $106.66 to undercut three quarters of the 16 listings you are competing with. $139.90 is the top of the normal range. These are asking prices rather than sold prices, so they tell you where to start rather than what you will get, and buyers compare delivered cost — price with shipping in mind.
How many used DeWalt 20V MAX 1/2" Hammer Drill (DCD999) are for sale right now?
16 listings for the DeWalt 20V MAX 1/2" Hammer Drill (DCD999) are live on eBay right now, ranging from $79.99 to $229.70. We verify each one names this exact part number and is the whole tool rather than a part or an accessory.
Does the DeWalt 20V MAX 1/2" Hammer Drill (DCD999) come with a battery?
It depends on the listing. DCD999 is a family number rather than a single product — DeWalt sells the bare tool and the kit under part numbers that both begin with it, and sellers routinely write just DCD999. The figures on this page cover both configurations, which is why the range is wider than for a single one. Check the individual listing title for what is included.
