How to Choose the Right Grinding & Sharpening Accessories

Selecting appropriate grinding and sharpening accessories requires consideration of several key factors:

Material Compatibility: Match the abrasive type to your workpiece material. Aluminium oxide stones work best on ferrous metals and steel, whilst silicon carbide excels on harder materials like ceramics, glass, and non-ferrous metals. Using the correct abrasive ensures efficient material removal whilst maximising accessory lifespan.

Stone Profile and Size: Consider the geometry of the work area. Cylindrical stones suit flat surfaces and external curves, whilst conical and spherical profiles access internal contours, tight corners, and intricate detail work. Ensure your chosen accessory can physically reach the work area whilst maintaining safe clearance from adjacent surfaces.

Application Purpose: Heavy stock removal demands coarser grits and robust stone construction, whilst finishing work requires finer abrasives and precise profiles. Chainsaw sharpening necessitates dedicated grinding stones matched to your chain's pitch and tooth geometry for optimal results. The Tooled-Up range includes specialist chainsaw sharpening kits alongside general-purpose grinding stones for maximum versatility.

Tool Compatibility: Verify that accessories match your rotary tool's collet size and RPM capability. Most grinding stones specify maximum operating speeds – exceeding these limits risks stone failure and potential injury. Dremel accessories clearly mark these specifications on packaging, ensuring safe operation with compatible tools.

Frequency of Use: Professional tradespeople undertaking regular grinding work benefit from purchasing accessory sets offering multiple profiles and grit ratings, providing versatility whilst representing better value than individual purchases. Occasional users might prefer targeted solutions for specific tasks.

Safety Information

Grinding operations present specific hazards requiring appropriate precautions and protective equipment:

Personal Protective Equipment: Always wear safety goggles or a face shield to protect against flying debris and abrasive particles. Grinding generates significant quantities of fine dust – use respiratory protection meeting HSE standards, particularly when working with materials producing hazardous dust. Hearing protection is advisable during extended grinding sessions due to high-pitched noise levels.

Speed Ratings: Never exceed the maximum RPM marked on grinding accessories. Operating beyond rated speeds can cause stone disintegration, creating dangerous projectiles. Ensure your rotary tool's speed setting remains within safe parameters for each accessory fitted.

Secure Mounting: Verify that grinding stones are properly secured before operation. Loose accessories can detach during use, causing injury and workpiece damage. Check mandrel tightness and collet engagement before each session.

Work Area Preparation: Maintain adequate workspace lighting and ventilation. Remove flammable materials from the grinding area as sparks generated during metalworking can ignite combustible substances. Ensure workpieces are securely clamped, preventing movement during grinding operations.

Inspect Before Use: Examine grinding stones for chips, cracks, or damage before fitting. Compromised accessories are prone to failure during operation and should be discarded immediately. Replace worn stones showing excessive reduction in diameter or profile distortion.
