Jargon Buster

• Shank Diameter: The size of the shaft that fits into the rotary tool's collet, typically measured in millimetres (1.6mm, 2.35mm, 3.2mm) or imperial sizes (1/16", 3/32", 1/8"). Matching the correct shank diameter to your tool's collet is essential for secure fitting and safe operation.
• Collet: The clamping mechanism that holds the accessory shank securely in the rotary tool. Different collet sizes accommodate various shank diameters, and some tools feature quick-change collet systems for faster accessory swapping.
• Mandrel: A shaft attachment that holds cutting wheels, sanding discs, or polishing mops. The mandrel screws into the accessory and is then secured in the tool's collet, allowing easy replacement of worn discs or wheels.
• Grit Size: Refers to the coarseness of abrasive accessories like sanding drums and grinding stones. Lower numbers (60-80 grit) indicate coarse abrasives for rapid material removal, whilst higher numbers (220-400 grit) denote fine abrasives for finishing and polishing work.
• RPM Rating: The maximum rotational speed at which an accessory can be safely operated, measured in revolutions per minute. Exceeding an accessory's rated RPM can cause failure and serious injury, so always match accessory ratings to your tool's speed settings.
• HSS (High-Speed Steel): A durable tool steel alloy used for cutting bits and burrs that maintains hardness even at high temperatures, making it ideal for cutting ferrous metals and demanding applications.

How to Choose the Right Rotary Multi Tool Accessories

Compatibility and Shank Size: Always verify that accessories match your rotary tool's collet size. The extensive range at Tooled-Up includes accessories with standard shank diameters compatible with major brands, but checking specifications prevents purchasing incompatible items. Some universal accessories fit multiple tools, whilst others are brand-specific.

Material and Application: Match the accessory material to your workpiece. Use carbide or diamond-coated accessories for hard materials like tile, glass, or stone; HSS bits for metal cutting; and standard grinding stones or sanding drums for wood and softer materials. Multi-material accessories offer versatility but may not perform as well as dedicated options for specific tasks.

Speed Rating Compatibility: Ensure accessories are rated for your tool's operating speed. Variable-speed rotary tools allow adjustment to suit different accessories and materials, with lower speeds typically better for polishing and higher speeds for cutting. Never exceed an accessory's maximum RPM rating.

Accessory Kits vs Individual Items: Comprehensive accessory kits provide excellent value and variety for general use, containing multiple accessory types suitable for diverse applications. However, professionals frequently performing specific tasks often prefer purchasing individual high-quality accessories in bulk, ensuring consistent performance and reducing per-use costs.

Quality and Durability: Premium accessories from established brands like Dremel, Bosch, and Fein deliver superior performance, longer service life, and better safety margins compared to economy alternatives. Reinforced cutting discs, accurately balanced grinding wheels, and consistently graded abrasives justify their higher initial cost through improved results and reduced replacement frequency.

Quick-Change Systems: Consider accessories compatible with quick-change mandrels and EZ-lock systems if your tool supports them. These systems dramatically reduce accessory changing time, particularly valuable for professionals switching between tasks frequently throughout the day.

Safety Information

Personal Protective Equipment: Always wear safety glasses or goggles when operating rotary tools, as high-speed accessories can throw debris considerable distances. Use a dust mask when sanding or grinding materials that produce fine particles, and wear hearing protection during extended use. Suitable work gloves protect hands from sharp edges, though avoid loose-fitting gloves that could catch in rotating accessories.

Accessory Inspection: Before each use, carefully inspect accessories for cracks, chips, or damage. Damaged accessories can disintegrate at high speed, causing serious injury. Never use cutting discs or grinding wheels that show signs of wear beyond their minimum diameter specifications. Discard any accessory that has been dropped or impacts a hard surface, as internal damage may not be visible.

Secure Clamping: Ensure accessories are properly seated in the collet and tightened according to manufacturer specifications. Loose accessories can work free during operation, causing loss of control. Use the correct collet size for each accessory shank diameter rather than forcing incompatible sizes together.

Speed Control: Operate accessories within their rated speed ranges. Consult HSE guidance on abrasive wheels if using rotary tools professionally. Start at lower speeds when using new accessories to verify proper balance and operation before increasing to working speed. Reduce speed when working with heat-sensitive materials like plastics to prevent melting.

Work Environment: Maintain a clean, well-lit workspace free from flammable materials, as grinding and cutting operations produce sparks. Ensure adequate ventilation when working with materials that produce dust or fumes. Secure workpieces properly to prevent movement during operation, and never hold small items in your hand whilst working on them.

Frequently Asked Questions

Are rotary multi tool accessories interchangeable between different brands?

Most accessories with standard shank sizes (particularly 3.2mm/1/8") are compatible across major brands including Dremel, Bosch, Makita, and DeWalt rotary tools, provided the shank diameter matches your tool's collet. However, some manufacturers produce proprietary quick-change accessories that only fit their specific systems. Always verify shank diameter and any special fitting requirements before purchasing. Tooled-Up stocks both universal accessories and brand-specific options to suit different tool types.

How long do rotary tool accessories typically last?

Service life varies enormously depending on accessory type, quality, material being worked, and operating technique. Cutting discs may last from a few cuts on hard materials to dozens on softer substances. Sanding drums with replaceable bands can handle multiple projects by simply replacing worn bands. Grinding stones and burrs gradually wear with use but premium carbide versions significantly outlast standard alternatives. Polishing accessories generally offer the longest service life. Proper speed selection, appropriate pressure, and regular cleaning extend accessory longevity considerably.

What's the difference between cutting discs for different materials?

Cutting discs are formulated specifically for different materials to optimise performance and safety. Metal-cutting discs typically contain aluminium oxide or silicon carbide abrasives bonded with reinforcing fibreglass layers. Stone and tile discs feature diamond particles for cutting hard, abrasive materials. Wood-cutting discs use coarser abrasives suited to softer materials. Using the wrong disc type can result in poor cutting performance, excessive wear, overheating, or disc failure. Always select discs specifically rated for your workpiece material.

Can I use rotary tool accessories at any speed?

No—each accessory has a maximum safe operating speed (RPM) that must not be exceeded. Operating accessories above their rated speed can cause catastrophic failure, potentially resulting in serious injury. Variable-speed rotary tools should be adjusted to suit both the accessory and material: lower speeds (10,000-15,000 RPM) work better for polishing and working plastics, whilst higher speeds (20,000-35,000 RPM) suit grinding and cutting harder materials. Always consult accessory packaging for specific speed recommendations and never exceed the maximum rating.

Do I need different accessories for cordless versus 240v rotary tools?

The accessories themselves are identical—compatibility depends on shank diameter and collet size rather than power source. However, cordless rotary tools typically operate at slightly lower maximum speeds than 240v corded equivalents, which may affect performance with accessories designed for very high-speed operation. Cordless tools excel at lighter-duty applications like engraving, fine sanding, and polishing, whilst corded 240v models provide sustained power for demanding grinding and cutting tasks. Select accessories appropriate to your intended application regardless of power source.
