So, what makes our 9” disk grinder different?  Well, I'm glad you asked! Yep that's right, it does both horizontal or vertical.  

This machine was designed and built by an engineer / tool & die maker with 40+ years experience in automation, robotics and precision fixture design. AMK, LLC has a history of engineering, design, and fabrication of specialty fixtures, automated work cells and production lines and we only design, build, and sell top quality equipment and products

This system includes a VFD with a 1.0 HP motor (that can rotate into horizontal or vertical position), 9” magnetic disk, adjustable 12” work table, and one removeable metal plate.



Standard Features: 

1. Uses standard 9” PSA disks. This model has a magnetic disk so you can quickly change for one grit to another by simply changing the metal plates. We will include one plate. Additional plates are $50. Please email us at to order additional plates.


2. Oh, and did I mention that you get the motor as well? Yep,  a 1.0 motor with a VFD, wired for 110vac motor that can be used horizontal or vertical.
