Customer Reviews for Erbauer Ground HSS Drill Bit 10mm Pack of 5
Review 1 for Erbauer Ground HSS Drill Bit 10mm Pack of 5
"At about £2.40 each I thought these would be good enough to drill some holes in a 6mm thick RSJ. Regrettably they each went blunt within seconds even if I first went through with a pilot. Fine of course in wood.
For the RSJ, I got through it with the De Walt Extremem 2HSS drills. Over twice as expensive but for this application, the only solution."
