Description

This kit provides an easy-to-install alternative to the noisy and fragile factory-installed gears that drive the spindle on the mini mill.

This kit is CNC-machined from the highest quality materials. Designed to run full-time, it is built to last. The kit includes one belt.

Change speeds without any tools. Simply remove the guard, loosen the lever locks and move the belt from one pair of pulleys to the other. Low speed range is 0-1700 RPM. High speed range is 0-4300 RPM.

The installation is bolt-on and takes about 20 minutes.

This belt drive fits the following mills:

Grizzly G0516 Lathe Mill Combo

Cummins 7877 Mini Mill

Grizzly G8689 Mini Milling Machine

Harbor Freight 44991 Central Machinery Mini Mill/Drill

Hare & Forbes HM-10 Mini Mill Drill

Homier 03947 Speedway Mini Mill

Micro-Mark 82573 MicroLux Milling Machine

The small pulley has a 9 mm bore with a 3 mm keyway. The large pulley has a 30 mm bore with a 5 mm keyway. If your shafts don't match these values, then this belt drive will not fit your mill.

Chris Chris' Tips
The belt drive increases the spindle speed significantly. This is great for small cutters that want to turn fast. However, it decreases the torque in inverse proportion to the speed increase. So you won't be able to drill holes as large as with a geared mini mill.

Here are the installation instructions.

Here is a review of the belt drive.
