Rated 1 out of 5 by from worst drill bit ever bought!!! Bought 2 packs to drill pilots for lining the back of my van. Drilling thru 2mm mild steel first one shattered immediately second one drilled 4 holes then shattered and yes i was using slow speed. Useless - intact i resorted to some 3 yr old Ryobi bits to complete the job which worked without a problem. Don't know whether this is manufacturing fault or not but would not buy again ever.
