    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.

    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.

    Quick-Change Lathe Tools and Holders

    Reduce tooling setup time—install the holder once and alternate between applications by switching out the bit. Once the holder has been aligned with the centerline of the lathe, the locking system ensures alignment repeatability from tool to tool.

    Boring Milling Machine Tool Holders

    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.

    Quick-Change Lathe Tool Posts

    Image of ProductInUse. Front orientation. Contains Annotated. Lathe Tool Posts.
    Image of Product. Front orientation. 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.
