Swozzto 3.28"&5.64" Forstner Bit Extension Set with Anti-slip Design | Adding Over 3.28"&5.64" Drilling Depth to Forstner Bit,Suitable for Process Wooden Furniture,Timber and etc.

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
