Rated 1 out of 5 by Tip went flying from two bits I was drilling a series of holes in a block of concrete immediately after purchasing these. I was using the size 5 to make pilots holes, and the size 6 to widen. Both lost their tips within five minutes rendering them totally useless. Next time I'm sticking with DeWalt. 6 Dec 2015
Rated 5 out of 5 by Worth the money Being a cheapskate, I normally buy cheap drill bits only to be disappointed when they snap in a partly drilled hole. This time, I decided to spend a bit more. These are great. They cut through bricks like a knife through butter - and stayed in one piece. Highly recommended. 12 Nov 2015
Rated 5 out of 5 by Indispensable Set - Buy it Excellent drills with good performance and last and last even on very hard surfaces. The inclusion of an (unusual) 3mm drill is the cherry on the cake as this allows very accurate drilling to be carried out with ease, 30 Jul 2015
Rated 5 out of 5 by A blessing Having been renovating a 17c house for some years where the walls are either too soft or very hard I had warn out all my old masonry bits. Finally bought these and I should have purchased some quality one years ago. Took all the pain out of fixing plumbing in awkward places. Good clean hole easily hammer drilled. Very good 26 Jun 2015
