3.5mm x 70mm HSS Cobalt Jobber Drill Bit

Code: 7035

Cobalt drills are incredibly strong, so they are ideal for drilling into very hard, abrasive and difficult to machine materials. They can perform well at high temperatures - because cobalt drills can resist heat for extended periods of time, they don’t need to be cooled and cutting fluid doesn’t need to be used.

  • Our PTI cobalt drill bits have a split point, which makes centre punching unnecessary and avoids skidding
  • Ideal for use on stainless steel
  • Supplied in a sturdy plastic tube
  • Diameter: 3.5mm
  • Length: 70mm
