Hole Saw for Wood, Bi-Metal HSS 30mm Hole Saw for Air Pipes, Quick and Smooth Cutting for Plastic, Plywood, Drywall, Plasterboard

M42 HSS and BI metal hole saws have higher hardness (≥65HRC), higher toughness, greater cutting force and greater wear resistance. Cutting efficiency and smoothness: high quality bi-metal band and the best cutting performance of HSS teeth combine with the clean non-binding edge design to ensure smooth and clean cutting of the hole saw blade. Wide use: hole saws can cut holes in wood, plywood, plastic, drywall, soft plaster, cornhole boards and thin metals. In addition to punching tin cans or recessed lights, punch saws are also suitable for household projects on air ducts, speakers, ceiling lights, etc. Install the pilot hole and hole saw, hold the drill straight on the cutting surface and drill clockwise at a slow speed and keep stable, so as to achieve a smooth and clean round cut.
