Choose the Correct Fit
Match the arbor, pilot and saw before assembly. Verify the saw-diameter range and drill connection rather than assuming universal fit.
Select the hole saw and pilot for the actual material. This cobalt pilot is specified for stainless steel, cast iron, wood and abrasive materials.
Installation & Care
Follow the arbor instructions for pilot projection and retention. Secure the work and brace the drill before starting.
Disconnect power before adjustments. Check the pilot tip and retaining hardware for wear or damage, and let hot parts cool.

Important Product Questions
Does the pilot’s fit make every saw compatible?
No. Pilot fit, saw-to-arbor fit and arbor-to-drill fit are separate checks. Verify all three before assembly.
Can this pilot drill stainless steel?
Yes. Stainless steel, cast iron, wood, metal and abrasive materials are listed applications. Match drill speed and lubrication to the material.
How far should the pilot project beyond the saw?
Set projection and tighten the retaining screw as directed by the arbor instructions. Do not guess from the pilot’s overall length.
