Adjustable Drill Drives Inventory Cost Savings
10/14/2008 Modern Machine Shop: During a difficult application, the inserts on this shop’s standard IC drill would sporadically fail, causing the entire tool to break down. This required the shop to stock a large inventory of costly replacements in various sizes to fit different-sized holes. Allied Machine and Engineering’s Revolution drill allows the shop to adjust tool diameter and cut holes of different sizes with a single tool, while replaceable insert cartridges on the front end keep insert failure from wrecking the tool itself.
