Description

This Cobalt Steel Twist Drill Set includes precision drills from 0.50 mm to 2.2 mm, each mounted on 3/32" shanks for fast, convenient tool changes. Cobalt steel offers improved tool life over high speed steel, especially when drilling harder materials such as nickel-based white golds and stainless steels. Expect consistent cutting performance and extended service life across both hard and soft precious metals.

Features

  • Cobalt steel construction for longer tool life than HSS
  • Performs especially well in nickel-based white golds and stainless steels
  • Extended service life when drilling yellow gold, silver, brass, and copper
  • All drills mounted on 3/32 in (2.35 mm) shanks
  • Ideal for fixed collet and quick change handpieces
  • Standard 3/32 in shank size widely used in the jewelry industry
