Choose the Correct Fit
Match the hole to the anchor or fitting. Support tile and other fragile material, and inspect the drilling path for concealed services.
Use a compatible drill and follow the saw’s starting and cooling instructions. A hex shank alone does not authorize impact or hammer operation.
Installation & Care
Keep the saw aligned and avoid side loading. Use the speed, pressure and water method specified for the bit and work material.
Isolate the drill before clearing the core. Let the saw cool and remove debris from the slot before storage.

Important Product Questions
Does the hex shank make it impact rated?
No impact rating is established by the hex shape. Use the drill and cutting mode specified by the saw instructions; do not assume hammer or impact use is permitted.
Do I need a separate hole-saw arbor?
This is a one-piece saw with a 1/4 in quick-change hex shank. Confirm the drill accepts that shank and is suitable for the intended material.
How do I avoid cracking tile or glass?
Support the work, follow the specified starting and cooling method, and avoid excessive feed pressure or side loading. Check suitability for the exact material before cutting.
