Frequently Asked Questions
What is the difference between Bi-Metal and Carbon Steel hole saws?
Bi-Metal hole saws use a High Speed Steel (M42) cutting edge welded to a flexible alloy body. This allows them to cut metal and stainless steel, lasting 10x longer than carbon steel saws which are only for wood.
Can your M42 hole saws cut stainless steel?
Yes, our M42 hole saws contain 8% Cobalt, specifically designed to cut tough materials like stainless steel. We recommend using low RPM and cutting fluid for best results.
Do you offer private label (OEM) service?
Yes, we can laser engrave your logo on the hole saws and provide custom packaging (blister pack, plastic tube, or kit box).
What arbors do I need?
Small diameters (14-30mm) typically use a 1/2-20 thread arbor. Large diameters (32-210mm) use a 5/8-18 thread arbor. We supply all compatible arbors.
