ROEBUCK CH20 VARI PITCH HOLE SAW 20MM

• Variable pitch, positive rate toothform to give a faster cut
• Slightly offset teeth of different sizes 4 tpi and 6 tpi resulting in swarf being cleared more efficiently, generating less heat than traditional holesaws
• Produced with a solid cap, which results in less vibration
• Teeth formed from M3 high speed steel for longer life
• Vacuum heat treated for uniform hardness
