• Attach to Tool: Insert the 3.17mm (1/8") shank into your rotary tool's collet and tighten it securely before switching on.

• Polishing Stage: Fit a felt wheel or polishing wheel brush for the final polishing pass.

Frequently Asked Questions (FAQs)

• What are felt wheels used for on a rotary tool?
  Felt wheels are polishing attachments used to buff and smooth surfaces. They work alongside polishing compound to address microscopic surface marks and restore shine. Their compressed fibre construction holds compound well and conforms slightly to the workpiece shape.

• Do radial bristle discs require polishing compound?
  Radial bristle discs are typically used dry. The abrasive grit is embedded into the bristle material itself, so no additional compound is needed.

• What does the grit number mean on polishing accessories?
  Grit number indicates how coarse an abrasive is - the higher the number, the finer the abrasive. A 320-grit disc removes material more aggressively than a 600-grit disc. Start with the lower grit to prepare the surface, then progress to the higher grit for a finer result.

• What PPE should I wear when using rotary tool accessories?
  Always wear safety glasses or goggles to protect against flying debris. A dust mask is also recommended when grinding or polishing, as both processes generate fine particles. Keep loose clothing secured away from the tool while it is in use.

• What is an arbor in a rotary tool accessory set?
  An arbor, also called a mandrel, holds accessories that lack their own fixed shank. The accessory mounts onto the arbor, which then fits into the rotary tool's collet.

Summary

Blue Spot Tools' 24-piece grinding and polishing set provides a full accessory range for rotary tool work. All shanks are 3.17mm (1/8"), giving compatibility with most rotary tool brands.
