Need to replace a worn-out pulley on your drill press, bench grinder, or other small machine?

This aluminum step pulley is a common and crucial part.

It's a \step\ pulley, meaning it has multiple grooves of different diameters, which allows you to change the speed of your drill bit or spindle by moving the drive belt to a different step.

Made from solid aluminum alloy, it's lightweight, strong, and resists wear and corrosion.

The multi-groove design provides stable power transmission from your motor to the spindle, with less vibration and noise compared to a cheap, off-balance pulley.

It's about 3.18 inches in diameter and comes in a standard silver finish.

Installing it is usually straightforward – you just need to match the bore size (the hole in the center) to your motor or spindle shaft, and make sure the outer dimensions and groove count match your old one.

This is a core hardware component for keeping your shop equipment running smoothly.
