Lathe Tool Holder Bushings for CNC Lathes
 |  |
 |
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.

Strong-Hold Round-Shank Tool Holders for Quick-Change Lathe Tool Posts
 |
Shown with Lathe Tool (Sold Separately) |
Four flat head screws lock down round-shank tools in a precision-ground bore for increased rigidity over other round-shank tool holders. A shoulder screw allows for quick and accurate adjustment of the tool height without the need for shimming. Posts and holders (sold separately) are interchangeable with systems from Aloris, Dorian, and Armstrong. Use with lathe tools (sold separately) that have a shank diameter that corresponds to the holder’s capacity.

Lathe Spindle Stops
 |
Position workpieces in the same spot every time to quicken setup, improve repeatability, and cut down on scrap. These stops create a repeatable position within your lathe spindle for clamping parts loaded through a chuck or collet. They fit a range of spindle bore diameters—the jaws expand outward for a secure, self-centering fit. To lock these stops in place, expand them with just a few turns of the T-handle wrench. They can be used on both CNC and manual lathes.

Quick-Change Lathe Tool Posts
 |
 |
Position and secure tools on manual and CNC lathes. Two slide-in dovetail mounts allow you to quickly change from one tool holder to another. The dovetail mounts are set 90° apart so you can mount tool holders on either side. A wedge-type locking system eliminates vibration and ensures repeated accuracy within millionths of an inch. Posts and holders (sold separately) are interchangeable with systems from Aloris, Dorian, and Armstrong.
Select the tool post series that matches your lathe’s swing and center height. Lathe swing is the maximum workpiece diameter that can be turned on the lathe. To find your lathe’s swing, measure the distance between the centerline of the lathe and the lathe bed and multiply by two. To find your lathe’s center height, measure the distance from the centerline of the lathe to the top of the compound. Choose the tool post series with an optimal center height that is closest to your lathe’s center height.
