ROEBUCK CH57 VARI PITCH HOLE SAW 57MM

• 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
