"i know that they where cheap but to drill one hole in 1.2mm sheet steel and then throw it away is not good value, it went blunt so quick it almost didn't manage the one hole! not impressed with this but you get what you pay for with drill bits"

Review 15 for Bosch HSS-R Drill Bit 4 x 75mm Pack of 2
"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."
