CNC machinists, listen up. Need to reach deeper into a part without buying a bunch of extra-long end mills? This C16-ER11-35L extension holder is your fix. It's a straight shank collet holder with an extended 35mm body length (40mm total with the nut). It uses ER11 collets (not included) and is available for 5mm, 6mm, or 8mm shank tools (this listing is for the 8mm version). It's made from hardened metal for durability and precision, and all the critical surfaces are precision-ground to minimize vibration and runout for a cleaner, safer cut. It essentially lets you use your standard-length tools for deeper holes, saving you money on special tools and increasing your machining flexibility. A must-have for your tooling collection if you do deep cavity work.,
