Description
The Procat mini grinder sanding and polishing set is a comprehensive 12-piece accessory pack designed for precision work, restoration and finishing. The set is optimised for use with the most common rotary tools and mini grinders on the market, giving you tools for precise material removal, surface cleaning and a high-gloss finish. The versatility of the product comes from using different materials such as nylon fibres, cotton and felt, which covers every step from light sanding to bright polishing.
The fibre wheels (non-woven abrasive) in the set are excellent for gentle cleaning and matting of surfaces. The green and red abrasive heads are made of durable fibre material that follows the shape of the workpiece without removing too much of the base material. They are ideal for removing oxidation from metals, removing old paint from tight recesses or preparing the surface before painting or gluing, for example. The fibre structure stops the wheel from clogging and guarantees an even sanding finish.
For polishing, the set contains several different felt and cloth wheels. The heads made of cotton and dense felt are excellent for use with polishing compounds to finish metals, plastics and gemstones. The supplied mandrel makes it easy to change the loose felt wheels, which makes work smooth. This set is an essential accessory for anyone doing precision work who needs reliable tools for handling small, complex parts.
Intended use:
The Procat set is designed for versatile applications that call for precision and careful surface treatment. The main areas of use of the set are listed below:
- Cleaning and restoring metal surfaces: The fibre wheels are excellent for removing rust, varnish, oxidation and dirt from metals such as steel, brass and copper. The flexible material reaches deep into grooves and corners that are hard to reach with conventional sandpaper.
- High-gloss polishing: Felt and cloth wheels are used together with polishing compounds to polish metals (such as aluminium, chrome and silver) to a mirror finish. This is common in jewellery making, finishing small machine parts and maintaining decorative items.
- Finishing moulds and small parts: Small burrs left by machining or 3D printing can be removed and the surface smoothed with the abrasive fibre wheels of the set without significantly affecting the dimensional accuracy of the part.
- Maintaining electronics and connectors: The gentle cleaning wheels are suitable for cleaning oxidation off electrical connectors and contact surfaces, improving conductivity without damaging the metal surface itself.
- Treating wood and plastic surfaces: The set can also be used for light sanding and polishing of hardwood and plastic, for example in model building or instrument repair.

Features:
The key features of the product and their benefits for the user are listed in this section:
- Standard-size mandrel: The approx. 3mm (1/8″) shank is compatible with most rotary tools and die grinders on the market (e.g. Dremel, Proxxon), which guarantees wide usability.
- Non-woven fibre material: The open fibre structure of the cleaning wheels does not clog easily with dust or dirt, which extends the life of the wheel and keeps the sanding performance even.
- Flexible construction: The wheels adapt to the shape of the workpiece, which stops flat surfaces from being dished and makes round shapes easy to work.
- Versatile range of materials: The set contains both abrasive (fibre) and polishing (felt/cloth) materials, so you can carry out the whole process from cleaning to polishing with one set.
- Replaceable heads: The supplied screw-on mandrel allows quick changes of the small felt pads and economical use, as only the worn part needs replacing.

Procat mini grinder sanding/polishing set instructions for use:
Before use, make sure the wheel you have chosen is intact and clean. Fit the wheel or mandrel carefully in the chuck of the rotary tool. Tighten the chuck according to the tool manufacturer’s instructions.
Cleaning and sanding (green and red wheels): Use a moderate speed (recommended approx. 5000–15000 RPM). Press the wheel lightly against the surface being worked. Pressing too hard can damage the wheel and leave an uneven finish. Keep the tool moving so that no hollow forms in one spot. The green wheel is usually coarser, so start with it and finish with the red one.
Polishing (felt and cloth wheels): Fit the felt pad to the screw-on mandrel by screwing it firmly into place. For the best result, use polishing compound (purchased separately). Apply compound to the rotating wheel and then work the piece. Keep the speed low to stop the surface from burning and the compound from spattering. Finally, clean the piece with a soft cloth.
Warnings:
Note the following safety factors when using the product:
- Always wear safety glasses. Bristles, fibres or workpiece material can come off the rotating parts at high speed.
- Do not exceed the maximum permitted speed of your tool or the wheel. Too high a speed can break the wheel.
- Beware of heating. Long sanding or polishing in one spot can make the workpiece burning hot.
- Wear a respirator for dusty work, especially when sanding paint or metal.
- Keep fingers, hair and clothing away from the rotating mandrel.
Frequently asked questions (FAQ):
Is this set suitable for Dremel tools?
Yes, the mandrel of the set is approx. 3mm thick, which is the standard size in most Dremel models and other similar rotary tools.
Do I need polishing compound with the felt wheels?
Yes, felt wheels work best with a polishing compound or wax suited to the material. Without compound, polishing performance is weaker.
Can wood be sanded with the fibre wheels?
Yes, the fibre wheels are suitable for light sanding, cleaning and texturing of wood. However, they are not as efficient at removing material as sandpaper.
