PCH051                     51mm Cobalt Vari-Pitch Holesaw

The ultimate multi-purpose holesaw with 8% cobalt for longer life

  • Stronger flex-free body construction is designed with high alloy content for structural integrity and tool dependability
  • Teeth are manufactured with M42 superior steel featuring 8% Cobalt which provides excellent wear resistance at higher drilling temperatures for extended tool life
  • Variable pitch cutting teeth combine an aggressive cut for increased spoil removal with a smoother cut for reduced vibration. This allows the holesaws to benefit from both increased cutting speed and tool durability
  • Irregular depth clearance gullets avoid trapped spoil by providing a more efficient chip clearance meaning teeth stay sharper for longer

CVP Holesaws can be used in:

  • Steel
  • Stainless steel
  • Non-ferrous
  • Wood
  • Plastics
  • MDF

User Instructions

  • Wear appropriate Personal Protective Equipment (P.P.E) when using holesaws
  • Ensure holesaw is correctly attached to the relevant adaptor for your machine
  • Use holesaw at the recommended speeds for the material being drilled as shown in the chart
  • Use an appropriate cutting lubricant when drilling in steel
  • After producing a hole, remove the “slug” of the material from the throat of the holesaw before commencing another hole
  • After pilot drill penetration, be careful not the “bang” the holesaw onto the durface of the material to be drilled. This could damage or break the cutting teeth

Tech-Tip

  • Our holesaws fit standard adaptors – please see our range of Holesaw Accessories for a tip on how to correctly fit your holesaw to your adaptor
