Rated 4 out of 5Â by djay7uk Works well, lasts as expected!
I buy these bits generally as I've tried the more expensive cobalt versions and for what I use them for I haven't noticed a huge difference in how long they last (Mostly plastic boxes, wood, plaster and the occasional metal consumer unit case).
I've had a couple of the cobalt versions just snap on me, obviously due to them being hardened.
For me, these work fine and do the job!! Cheap enough to just replace when they go blunt!!
