Holemaker Technology Spring Loaded Weldon Shank Arbor Extension - 100MM

A unique Magnet Drilling extension accessory developed by HMT, specifically designed for use in extreme depth drilling applications, where multiple extension arbors are mounted in series to achieve the required drilling depth. Traditionally this application meant it was not possible to use a pilot pin with your broach cutter, leading to drilling instability. However, the Retractable spring-loaded extension arbor is designed to be used at the bottom of a series of extension arbors, meaning a standard pilot pin can be used with the broach cutter and used in normal operation, like with a standard spring loaded magnet drill arbor.
