💡 how does a bi metal hole saw stay cool when drilling through hard pine boards or galvanized duct? A steady motor speed and tight arbor hold make this cutter really handy for shop work any day. The alternating tooth geometry grabs fresh bites so friction stays low. Keeping your feed rate steady stops the pilot shaft from heating up on thick lumber. Adding a drop of cutting oil on metal stock clears the gullets for clean breakthrough.
