Bosch Twist Cobalt Straight Shank Drill Bit 5.5mm x 93mm (660TJ)

Provides long-lasting performance when drilling stainless steel. This extended lifetime results from a cobalt alloy content of 5% and fully-ground HSS (high speed steel), which provides excellent surface quality, wear resistance and heat protection. Equipped with 2 cutters and 2 flutes, chips are removed quickly to make the bit last even longer. Active cutting and perfect centring without wandering are achieved by the pointed split-point tip. Works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid and heat-resistant steels. It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers.

  • Suitable for Alloyed & Non-Alloyed Steel, Stainless Steel, Acid & Heat-Resistant Steels, Cast Iron & Cast Steel
  • 57mm Working Length
