Review on Professional Grade 10Mm Cobalt Steel Twist Drill Bit - Heat Resistant For Stainless Steel And Cast Iron - Straight Shank Design - M35 Grade HSS-CO With 5% Cobalt - 1 Piece by Tony Trotter

Revainrating 5 out of 5

Accurate Sizing - 10mm bit measured 9.99mm with digital caliper

I needed to drill a 10mm hole in aluminum, and this bit worked nicely. The bit is well made, with clean grinding, good cutting edges on the twist, and good grinding at the point. I measured the bit diameter with a digital caliper, and the 10mm bit measured 9.99mm which is excellent. Would buy it again.
