Expensive, but they are exceptional drills. I needed a short 16mm wood drill to get through joists for cables, and it needed to fit the 10mm chuck of my 14.4v drill and get between the joists. This has a 6mm (I think) standard fitment so it was spot on. It chews up the wood especially at slow speed, for some reason the last bit to bust through takes a push. Brilliant drill bit, but should be for the money!

Rated 5 out of 5Â by elysium Decent wood bit
Used these bits for many years for drilling through floor joists with no problems I use a 18v impact driver which will drive the 25mm bit through easily .I always use an impact drill with any wood bit, because of the way the impact driver works they can be used one handed - I never use an ordinary drill I have too many twisting on me even with the clutch - a plumber I know broke his wrist drilling a floorboard so be warned.

Great kit as they've all said, and cuts a tidy hole relatively easy through joists. The lead-screw end pulls it through. However the last few millimeters need a bit more force which causes a rough exit. This is because the screw is no longer pulling it through, and theres a large area of cutting edge. No problem unless you're really short of space to push it through. The main issue to watch is that the 25mm bit needs about 25Nm torque. My Ryobi which is purpose made for the tight spaces cannot acheive enough torque for this bit, even though it easily drives a normal 25mm lead-screw bit through.
