DW999K-2 [Posted on 2001-07-25]
It's great to finally have an 18-volt version available from DeWalt. Now I don't have to drag a 50' extension cord behind me every time I need to install Tapcon fasteners or lag shields to mount enclosures or conduit straps. I had considered the DeWalt DW004 24-volt hammer but didn't care for the extra bulk or the idea of having to change to another battery system, primarily because I already have and use a collection of other DeWalt 18-volt tools. The DW999 is fast and does hit surprisingly hard, even harder than the Bosch 24-volt, which I do not own but have had the opportunity to use frequently in the past. It does feel slightly nose heavy and unbalanced, with or without the battery installed, compared to the older corded Bosch 11212VSR (predecessor of the Bosch 11224VSR) that I'm used to. This means you need to apply a little more forearm when using a Condrive tool for fastening or when reaching out to drill one- handed from a ladder or platform. Speaking for myself, in this type of work situation, the D-handle as this tool has, is the only way to go. The rotation-only feature does add versatility and comes in handy for using an SDS to straight (geared) chuck adapter to drill wood or light metal, but a stop-rotation impact only feature would also have been nice to allow for light use of a scaling chisel to smooth out seams and remove slag on poured concrete walls for mounting electrical boxes or conduits. Because it is reversible though, my primary field-use for this tool is for installing 3/16" and ¼" Tapcon fasteners, ¼" to 3/8" conical masonry anchors and 3/8" to ½" lag shields with a maximum hole size of 5/8". Battery life for this type of work has been better than expected but it's still a good thing that the kit includes two XR packs because you will definitely need them both for any type of extended use. If you need to use it on the go a lot, the vehicle charger may also be a good investment. The plastic storage case interior is a little small and doesn't have much room to store bits, attachments or boxes of fasteners, so you'll need to allocate more storage space in your already overcrowded service vehicle for these items. Overall, I am pleased with the tools performance and even with the high price, which I feel is a lot for an SDS hammer with a 7/8" capacity rating, it has proven itself to be an asset, as most cordless tools are, through time saved and convenience. I would recommend it for individuals who routinely install light to medium duty small diameter fasteners and need to do this type of work in job site areas where power is either difficult to obtain or unavailable.

Two more unrelated productivity tools I would like to see DeWalt make available for my service truck are an 18-volt ½" heavy duty right-angle (RAD) drill similar to Milwaukee's 3109-21 and a 18-volt fluorescent area work light similar to Bosch's 3450K.
