Rated 5 out of 5 by from Best I have used. No need for pilot hole, simply punch the mark and drill. I use a little wd40 to keep it moving and helps to cool. High speed seems to work best and drill in 3mm stages to keep it from getting too hot. I doubt this is necessary but makes them last very well. Very impressed. Only buy this version now for each size as needed.

Rated 5 out of 5 by from Good bits The people who 1 star these bits don't know how to use them and are probs nackers snapping them by snagging them or stopping halfway to cool and leaving a chewed swarf then starting and catching the swarf lip with full spin and shattering. I think they are tungsten they are quite brittle but mash through steel. Drill slow and cool them every 15 secs they go through like a blowtorch through butter. Ignore the divs these are the best out there. Bosch are like baby toys compared to these and they are same price.

Rated 1 out of 5 by from Disaster After seeing previous reviews I can only believe that I have been unlucky. Bought Saturday and broken on first use Sunday. Using a battery powered drill on stainless steel the drill snatched and broke the carbide cutters from the drill. I can only presume a manufacturing fault and will be returning at my earliest opportunity.

Rated 5 out of 5 by from Ace Drill Bit Excellent drill bit. I've used it on 10mm I Beams which it copes with no problem! Definitely recommend using WD40 Lubicant oil when drilling for best performance and longevity of the drill bit.

will a 12mm bit drill through metal using a 18v drill on low speed.

my drill is a dewalt and with bog standard diy drill bits it needs me to use pilot holes and increasing bit size to get up to 12mm in steel.
