Tungsten Grit Hole Saw
Designed to drill Hardiflex, Villaboard and other compressed sheeting products.

- This item requires an arbor
- It is recommended that the high speed steel drill bit, that is standard with our HSA1 and HSA4 arbor, is used only as a guide in a pre drilled pilot hole, or removed and a template used.¬¨‚Ä† The high speed drill bit will become dull very quickly if used to drill compressed cement products.
