Weeke BST 100 CNC throughfeed drill The Weeke BST 100 CNC throughfeed drill, available from Stiles Machinery, combines the boring and drilling capabilities of traditional throughfeed machines with drill pattern changeover times that are quicker than CNC point-to-point equipment. This makes high volume, small batch production efficient and more profitable. The BST 100 features computer-controlled set-up of drilling patterns, dowel drivers, backstop and clamp positions; high-speed drill bit positioning during processing; independent, individually-selectable drill spindles; and fully integrated software and controls.
