Review on High-Quality 9Mm M35 Cobalt Drill Bit For Cutting Hard Metals - Straight Shank, Extremely Heat Resistant, And 5% Cobalt M35 Grade HSS-CO by Robert Hoge

Revainrating 4 out of 5

Check your size!: my feedback

The ad says 5.2mm, the label on the package says 5.2mm. The drills are etched with 5.5mm.Fortunately I spotted this before drilling the holes for a 6x1.00mm tap.

Pros
  • For the price you can’t go wrong
Cons
  • Expensive compared to other drill bits on the market

I read several reviews reviews that stated they were not 6mm. They are correct in saying the size is under 6mm. Unfortunately I needed to be exactly as specified in the description. This item is useless for my purpose.
