Rigid-Hold Round-Shank Tool Holders for Quick-Change Lathe Tool Posts
Four flat head screws lock down round-shank tools in a precision-ground bore for increased rigidity over other round-shank tool holders. A height-adjustment 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.

Square- and Round-Shank Tool Holders for Quick-Change Lathe Tool Posts
A V-groove enables these holders to grip round-shank as well as square-shank tools. Height-adjustment screw allows for quick and accurate tool height changes 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 dimensions that correspond to the holder’s capacity.

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.
Tool posts with blank T-nut come with a T-nut that must be machined to fit your lathe’s T-slot.
Tool posts with custom T-nut come with a T-nut that has been machined to fit your lathe’s T-slot. To order: Provide the base width, base height, slot width, and overall height of your lathe’s T-slot.

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.

Boring Tool Holders for Milling Machines
Instead of widening a hole using a lathe, which turns the workpiece while the cutting tool stays still, use these holders to turn your boring bar in a milling machine and keep the workpiece stationary. They’re good for creating holes that are too large to drill or a diameter you don’t have a drill bit for. To help you bore holes to precise diameters, these holders have an adjustment dial with fine increments. Mount them in your milling machine using their shank. They’re also known as boring heads.
Holders for interchangeable shanks work with various hole sizes and machines. Add a compatible shank, these holders do not include one.
