Excellence through craftsmanship

Attention to detail is critical when you are working with Machine Tools. When I restored my Bridgeport I wanted to use R8-ER32 tool holders and wanted to torque the holders using a torque wrench. I was disappointed to discover that these custom torque wrenches could cost as much as $1,000 when I really wanted a torque wrench adaptor.  So I set out to make that adaptor, and I’m pleased with the results.

Outstanding tool

Tool works as it should. The fit and finish are excellent. I love that it has a QR code to find the correct Ft.lb. for your torque wrench. Above all else it was reasonable price and I didn't have to buy a specialized torque wrench and adaptor to tighten ER style collets. I have added the other sizes to my collection that he sells, ER40, ER32, ER25 and a custom 2.25 Hex that I use for TG100 collet nuts. All have perform outstanding and if I need more I will be buying them from Martin Precision Tools.
