Apart from the price, I would reccomend these to any one who wants to drill floor joists. I recently had to run some cat6 network cable under the floor upstairs. I used the 20mm stubby beaver (to get inbetween the joists) and it chewed through the wood like it was butter. I brought this product having brought the long 12 mm version to a job and liked the performance. I would recommend it's used with a impact driver in stead of drill simply because the impact action of the driver breaks the wood chips up and because the chips are smaller the cutter does not clog up, saving you time not having to pull the cutter out to unclog the hole. It also has the 1/4 drive on the shank so it fits in most impact drivers as well as most keyless chucks on drills drivers etc. I have also used it on plastic facia, because of the sharp tooth design on the outside of the flutes you get a clean cut hole (less deburring required) that you wouldn't get with a hole saw or normal drill.

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!

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.
