Forstner Bit Extension Set for Woodworking With Anti-Slip Design, Adds Extra Drilling Depth

About this item

• Simple & Efficient:When we need to drill deeper holes in certain woods,normal forstner bits are often not long enough;So we offer two extensions for drilling depths of 3.28" and 5.64" deeper,which require only simple installation for deeper holes
• 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
• Good Tools Require Good Materials:Our extension poles are built with rugged,high carbon steel for structural stability,with precision ground and polished surfaces;The shanks are 3/8" in diameter and will fit most drills
• Great Value Set:Cost-effective set,1PCS Forstner Bit Extension (3.28" Drilling Depth) +1PCS Forstner Bit Extension (5.64" Drilling Depth)+1PCS hex key
