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 Kavon Wiley

Like a hot knife through butter

This bit is proof (in a good way) that you get what you pay for. Needed to fabricate a water fitting for a temp gauge in my project car. Burned through 4 sub-standard bits in a drill press before getting this bit. Only took about 10 seconds to do the job with this bit. Highly recommended!

Pros
  • Looks like a quality product that will do the job for a long time.
Cons
  • Not 5mm, but 4.9mm. I can’t fit a 5mm rod in a 4.9mm hole.
