Product details

29 piece set of Extreme Cobalt metal drill bits, delivering superior drilling into metal. Featuring a non slip shank, a no-walk tip for curved surfaces and a strong central Core that improves fracture stability, particularly in freehand use (4.8mm diameter and up).

  • Suitable for portable or stationary drilling of high alloy content steels and metals with a tensile strength up to 1100n/mm²
  • The 'no-walk' tip allows for easier penetration of all surfaces (5mm and above). Cleaner, more accurate, burr-free holes due to recessed cutting wings
  • No slip shank; spin proof three sided shaft for optimal grip in drill chuck
  • Tough Core - Increasing the central Core thickness towards the chuck improves fracture stability, particularly in free hand use.
  • Faster Drilling - A combination of the optimized tip and flute geometry help deliver up to 4x the penetration speed (vs HSS-r metal drill bits)
  • Application - Ideal for harder metals such as including bronze, cast iron, stainless steel and titanium
