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.
