Review on 4.2Mm Metric M35 Cobalt Steel Extremely Heat Resistant Twist Drill Bit Of 2Pcs With Straight Shank To Cut Through Hard Metals Such As Stainless Steel And Cast Iron, 5% Cobalt M35 Grade HSS-CO by Tim Thomason

Revainrating 1 out of 5

No tapered end for drill chuck

Impossible to use unless you have a rotary hammer with a wanted to chuck because even a half inch hammer drill won't fit 14mm. I've never seen a big drill bit like this not be tapered down to fit a drill so I returned it because it's impossible to use

Pros
  • Tools & Home Improvement
Cons
  • May not cut as smoothly as some other types of bits.
