Radial discs are made of grit impregnated plastic, they produce a uniform finish throughout their life with no mess as no compound is necessary. The flaps make these wheels cool running, non-loading and flexible- Ideal for getting into very fine detail.
These smaller wheels are perfect for delicate detailed work, ideal for threads, slots, lettering, jewellery, compound free polishing etc
Grades of Radial Discs
Wheels are helpfully colour coded to identify grit. There are two different ranges for 25mm and 19mm radials.
36g – (Brown) Coarsest- for the most aggressive cut.
50g – (Dark Green) Very Coarse for rapid scratch and burr removal
80g – (Yellow) Coarse for rapid scratch removal, very good for firescale removal on silver. Leaves a satin finish.
120g- (White) Coarse for scratch removal.
220g- (Red) Medium for light scratch removal
400g- (Blue) Fine for prepolishing
Pumice- (Pink) For very light scratch removal and deburring. Good for threads.
6 Micron- (Peach/Orange) Gloss finishing
1 Micron- (Light Green) High Gloss finishing, leaves an excellent polished finish
Used For Radial Discs
3M radial wheels are popular in the jewellery polishing trade where there is a great deal of detailed polishing. The 19mm wheels are perfect for small scale work such as this but are not limited just to precious metal. Radial wheels work on all metals and much like bristle wheels won’t lose the definition and crisp edges. Ideal for threads and slots on Precision Engineering components. Useful where compound is not suitable. The wheels work with no compound to work from cut to polish even on hard metals. Suitable for polishing items which cannot be polished with compound containing animal fats or where items are not easily cleaned after polishing.
Many Precision Engineers Use these discs in CNC machines for Automatic Deburring of precision components. Excellent on Bores and threads for deburring, cleaning and polishing.Â
As these discs are cool running they are excellent for use on plastics, rubbers etc.
Uses for Radial Discs:
Use 19mm radial Discs with an MM503 Screw Top Mandrel. This screw top mandrel allows for several laps to be used, simply unscrew the screw top and fit your chosen number of laps before tightening the screw. We recommend 3+ wheels to be mounted for best results, we also advise not exceeding 6 laps for this particular size.
Radials must face the correct direction to avoid snapping off the teeth.
These mandrels are available on a 2.35mm and 3mm shank which are suitable for pendant motors, dremels, hobby tools, air tools and micromotors. Please check your particular tool for the size it will take.
