"I've not used this on anything really tough yet but so far quick, clean effortless drilling. I like the unusual tip which does seem to work and give more accurate results. Very tempted to get a full set of these now."
"My father always told me to buy the best tools I could afford - I bought cheap HSS bits to drill out some 8mm bolts and wasted my money. This bit drilled out all 6 bolts with ease and still looks new. Job done and lesson learnt."
"This bit was better than expected. It is HSS ground and made in Germany unlike other bits I could mention. Used with cutting fluid these breezed through stainless steel 3mm. I have done 30 holes so far and still looks new. No wandering and cut immediately. I usually use Heller or Gurhing but needed to complete a job quickly. Excellent substitute will go for the 10mm and see how it performs."
There's no need for a centre punch, as the tip holds its position well on start up. They are typically at least twice as fast as conventional HSS bits and the whole team use them as their preferred choice. Worth every penny!
Top Tip: We've found it better to slow the larger drills right down once the main part has started cutting, as they cut more efficiently, overheat less, and don't snatch once they break through. Otherwise they are so sharp that they can pull through suddenly."
"I purchased some 40x40x4mm box section for chainlink posts, at 61 I did not relish the thought of drilling the 42 x 10 mm holes for the eye bolts, I saw the reviews for these drills and thought give them a go. I purchased three, used one, really made the job easy using an 18v rechargeable drill . Drilling at low speed with medium pressure went through like a hot knife through butter. Very pleased with my drills and now have 2 spare for future projects. Eric"
"I was absolutely dreading drilling 12mm holes in some steel supports had to drill about 14 holes this thing went through them like butter I've never used a bit like it I did 14 holes in less than an hour was expecting to take all afternoon!! don't bother with the cheap ones although a little expensive its worth it 100%!!"
"Beats the cheaper 'throwaway' HSS bits by a country mile... clean cuts, a lovely continuous swarf even through the 8mm thick flange of a steel beam. Goes through steel about 4 times faster #keep the drill speed slow though# simply because it just keeps on cutting without losing an edge"
