Tool Holder Bushings for CNC Lathes
Bushing
Increase the diameter of boring bars, drill bits, and other shank-style cutting tools to securely fit CNC lathe tool blocks. These bushings are machined and ground to precisely fit both tools and tool blocks for optimal performance. Made of hardened steel, they are durable and stand up to the strain of CNC machining. They’re Style C bushings, which means they have a slot in the side that clamps tools regardless of where tool-block set screws are located, making them compatible with all tool blocks.

Carts for CNC Tooling
