Product Information

Description

These pulleys change the spindle speed range to 5000 rpm max.
The increased speed is great for small cutters such as those used for engraving. Just remember that doubling the speed will cut the torque in half.
This high speed spindle kit uses the same belt as the standard drive pulleys.
We do not have installation instructions completed yet, so you are on your own for installation.
Switching pulleys to the original set shouldn't take more than 20 minutes.

Chris's Tips

If your machine is not a LittleMachineShop.com HiTorque mini mill you need to get the High Speed Spindle Kit that includes replacement bearings. The factory bearings are not rated for 5000 RPM.

The LittleMachineShop.com HiTorque Mini Mills have genuine NSK bearings that are rated for well over 5000 RPM.
