Review on πŸ”§ Triumph Twist Drill Co 033332: Unbeatable Precision and Quality in Drilling Efficiency by Michael Boyle

Revainrating 5 out of 5

Sharp and durable drill bits

I bought this pack of 6 because I needed to drill hundreds of holes in 1/8" mild steel, some of them with a hand drill. , and have dulled or broken quite a few TiN-coated nameless bits. They cut steel like wood and I haven't dulled any despite intensive use. I liked them so much I bought a full size set of the same brand and variant (Trinado).

Pros
  • High speed steel for general use when drilling a variety of materials
Cons
  • Ugly pack
