Rated 4 out of 5 by Erbauer expansive drill bit Only drilled two 65mm. deep holes so far, so a bit early to make valid comment but the drill appears to do the job. My old expansive bit lasted many years hopfully this will give the same service 31 Mar 2016
Rated 3 out of 5 by Good solid expanding bit. Needed to drill 50mm holes in the end of newel posts and the only way to do it in situ. Drill is well made and surprisingly heavy, but that is what I have come to expect with this brand. Cutting into the end grain caused the bit to wander considerably on one hole requiring truing up with a hole saw, something you don't get with flat wood bits. Will never replace flat wood bits or decent hole saws but does the job. Gets very hot and causes the drill to get extremely hot (and yes it is a DeWalt) so lots of cooling down time when drilling 70mm deep holes. 28 Mar 2016
Rated 5 out of 5 by Great bit of kit As I needed to drill a hole between the standard bit sizes I was happy to find this adjustable bit. Although it is marked in 2mm increments, you can effectively set it to any size between 22 and 76mm. As I said, great bit of kit. 19 Mar 2016
Rated 1 out of 5 by expansive drill bit bought this some time ago to keep in the tool bag just in case.and what do you know, the time arrived i needed to cut sixty mm hole, thought this was the tool for the job, not a chance , put long cutter in tightened up , cutter fell out, and will not tighten, useless, expected better from erbauer, 11 Feb 2016

Answer: 
Hi Fishi,

This will cut a clean hole but there will be breakout on the exit so would advise a sacrificial bit of wood on the exit if this side needs to be clean also.

Thank you for using Q and A.
