Used for:

For Jewellers

3M radial wheels are popular in the jewellery trade because they are particularly good at detailed polishing. However they are not restricted to precious metal, they’ll even work on wood. Radial wheels work on all metals and much like bristle wheels won’t lose the definition and crisp edges.

These sizes need to be used as a brush on a bench polisher. Select the plastic screw taper for mounting the wheels on a taper pigtail.

For Engineers

Useful where compound is not suitable, therefore they are very popular in the dental or medical trades and where items need to be kept clean. The brush format of these wheels makes them really handy for getting into threads and slots. The plastic legs are relatively hard wearing but work better in larger number to improve their strength.

 

Used with: 50mm & 75mm Radials are used with either a mandrel or centre busch as per the mandrel options. The MM506 Mandrel features a reverse thread to ensure the mandrel does not loosen. This mandrel has a 6mm shank suitable for some air tools, drills, micromotors, flexshafts that take a 6mm spindle.

The plastic centre busch allows for several laps to be put together to form a brush for a polishing motor. The centre bush features a tapered bore to suit tapered pigtails. Both options are reusable, simply replace the radial laps when worn.
