1 1/8″ O.D. HOLECUTTER

The patented, made in the USA, Evergreen Cutters for stainless steel utilize a three tooth design to concentrate the force on a minimal surface area. This produces a higher cutting pressure per tooth than conventional hole saws. The cutters have an aggressive rake angle, high back clearance and minimal curf (width) to be able to cut underneath the work-hardening surface to softer material. The cutter body is tapered inside and out to minimize friction and heat build-up. These cutters use a patented 4 start thread to provide greater torque transmission through the thread and make the cutter removal much easier with the use of the loosening washer.
