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 Derrick Wilson

Revainrating 4 out of 5

Check your size! best in my review

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
  • Flutes Form - 2 Flutes Form Helps Clear Chips And Debris Away From The Bit, Decreasing Friction And Heat For A Faster, Cooler Drilling Process, Chatter-Free Design With Staggered Cutting Teeth Ensure The Precise Countersinking And Hole Smooth Clean.
Cons
  • Not as widely available as standard drill bits
