SEE datasheet for BEST PRACTICE GUIDELINES

ONE HOLSESAW FOR A WIDE RANGE OF MATERIALS

  • Unique tip design allows for drilling of multiple materials
  • Vacuum brazing enables extremely strong bond between body and diamond – giving resistance to excessive heat build up
  •  Thin walled for rapid penetration & heat resistance

Best Practice Information for Holesaw Drilling
For materials not suited to the use of the pilot drill i.e. tile:
1. Start by drilling at 45 degrees, creating a ‘smile’
2. Raise to a vertical position to continue drilling
3. Rotate slightly to ensure easy removal of material slug

For all other materials:
4. Use the pilot drill inserted into the correct holesaw adaptor. This will penetrate the material first and then guide the holesaw to completion

Use coolant if the material requires it to reduce heat build up
