Accessory set Vorel 25410 — 13-piece mini grinder bits, 3.2 mm shank for precise grinding and modelling

Vorel 25410 is a 13-piece accessory set designed for mini grinders with a 3.2 mm shank. The set contains a selection of grinding and modelling bits intended for precise material removal, shaping, deburring and finishing on metal, wood, plastic and composite materials. Components are sized for fine-detail work and fit standard 3.2 mm collets used in hobby and repair mini grinders.

Advantages

The assortment provides a range of abrasive shapes and profiles to address different tasks without changing tools frequently. The small 3.2 mm shank ensures compatibility with most mini grinder chucks and allows stable rotation at high speeds for controlled material removal. The set supports both coarse shaping and fine finishing, enabling transitions between rough and detailed work within the same kit.

Suitable for

• Model making and scale hobby work
• Detail sanding and shaping of wooden components
• Deburring and surface preparation on metal parts
• Plastic and composite trimming and finishing
• Small repair jobs and prototype adjustments

Key specifications

• Number of pieces: 13 bits
• Shank diameter: 3.2 mm
• Intended tool type: mini grinder / rotary tool
• Typical applications: grinding, shaping, deburring, finishing
• Compatible materials: metal, wood, plastic, composites

How to use

Select a bit appropriate for the material and desired finish, mount it securely in a compatible 3.2 mm collet or chuck, and tighten according to the grinder manufacturer’s instructions. Start at low speed to check balance and clearance, then increase speed gradually while applying light, even pressure. For best control, use short passes and let the abrasive do the cutting rather than forcing the tool. Regularly inspect bits for wear and replace them when performance declines.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, gloves and a dust mask. Use clamps or fixtures to secure small workpieces, maintain steady hand positioning, and avoid excessive side pressure that can break bits or damage the workpiece. Match bit shape and grit to the material: coarser profiles for rapid removal, finer profiles for smoothing and finishing.
