DeWalt DC927KL Li-Ion Hammerdrill/Driver
January-5-2008

I purchased the DC927KL at the beginning of November 2007. However, the rotational brake mechanism failed earlier this week after just light use in the past two months.

The drill is better balanced than the DC925, the half pound lighter weight is noticeable. The separate torque and mode selector rings make it very easy to use. DeWalt seems to have solved the problem with the DC925 and earlier models of it being difficult to switch from one speed range to the other.

The DC927 worked well in drilling wood (up to 1/2"), and 5/16" (and smaller) holes in concrete and brick. It has a nicely adjustable clutch for driving screws.

The circuitry in the Li packs makes it difficult to know when you are near the end of the useful charge of a battery pack. The battery will not run the drill (or even make the bulb in a DW919 worklight glow) when the pack gets below a certain point. Apparently the Li-Ion cells have to be protected from a potentially damaging complete discharge.
