Rotary tool accessories for grinding, sharpening and engraving on hard surfaces with reliable abrasive action. Handy for DIYers and tradespeople who need neat, controlled detail work, Dremel Silicon Carbide Grinding Stones bring confidence when shaping stone, glass and non-ferrous metals. Are they robust enough for regular workshop use?
⚡ At a Glance
- • Grinding Performance: Aggressive material removal on hard substrates while still permitting controlled detail work
- • Best for: DIY enthusiasts, stonemasons and glassworkers needing precise small-scale grinding and engraving
- • Not ideal for: Large-area metal removal jobs or exclusively ferrous-metal cutting tasks
Silicon carbide grinding stones with a compact bullet profile and 3.2 mm working diameter suit fine-detail grinding. Compatibility with 3.2 mm shank rotary tools makes them straightforward to fit and use.
Precise material removal – thanks to silicon carbide abrasive
Silicon carbide is a hard, sharp abrasive that cuts brittle and hard materials by fracturing small particles away from the workpiece. The grain structure maintains cutting action rather than glazing quickly.
Fast, reliable removal on stone, glass, ceramics and porcelain makes shaping and refining edges efficient. Users can expect fewer passes when tackling stubborn spots.
Fine detail control – with 3.2 mm working diameter and bullet shape
A small 3.2 mm working diameter combined with a bullet profile concentrates abrasive contact onto a compact area, allowing narrow grooves and curved contours to be worked precisely.
Tight access and accurate engraving are possible on small features and internal curves. Ideal for jewellery repair, grout work and delicate finishing.
Workshop-ready compatibility – thanks to 3.2 mm shank and universal fit
A 3.2 mm shank fits standard Dremel Multi-/Rotary tools and other rotary tools that accept the same shank size, while a recommended maximum speed of 25,000 RPM sets a safe operating envelope.
Straightforward fitting across common rotary tools reduces the need for adaptors. Users can swap accessories quickly and run the stones at appropriate speeds for safe, consistent results.
