• Non-slip Design:The traditional forstner drill extensions were prone to slipping when working with hardwoods, so we developed a non-slip design for the part that attaches to the drill rig, so that the drill jaws can firmly grip the extension
• Note:The inside diameter of our forstner drill bit extension collet is 3/8 inch,so it will only fit forstner drill bits with 3/8 inch or smaller shanks;Tighten the screw before use to prevent the drill bit from slipping when rotating at high speed
