## Long description

Diamond Grinding Burr EXO EXO FREZ Z PIASKOWCA Cone 3.3 mm is a rotary tool bit designed for shaping and detailing sandstone and other soft stone materials. The conical profile with diamond-coated surfaces provides controlled material removal and access to narrow or recessed areas. With a 3.3 mm shank, this burr fits most compact rotary tools and die grinders used for stone sculpting, model making, restoration and precision stone work.
Advantages
The diamond coating ensures consistent cutting performance and longer life compared with conventional abrasive bits when used on soft stone. The conical shape allows for precise profiling, edge rounding and intricate detail work in confined spaces. A standardized 3.3 mm shank provides stable mounting in chucks and collets of compatible rotary tools, enabling steady rotation and accurate control during use.
Suitable for
 Shaping and profiling sandstone and similar soft stone
 Detail grinding in stone sculpting and model making
 Restoration of carved stone elements and architectural details
 Creating small grooves, chamfers and rounded edges in stone
Key specifications
 Tip profile: conical (cone)
 Shank diameter: 3.3 mm
 Abrasive type: diamond-coated surface suitable for soft stone
 Intended materials: sandstone and similar soft natural stone
 Tool compatibility: rotary tools and compact die grinders with matching collet/chuck
How to use
Secure the 3.3 mm shank in the collet or chuck of a compatible rotary tool, ensuring it is tightened and centered to avoid runout. Start at low to moderate speed and gradually increase if required, keeping steady pressure and avoiding excessive force that can clog the diamond surface or cause uneven removal. Use short passes and maintain a consistent angle to achieve controlled shaping and finer detail. Periodically clear debris with a brush or compressed air and, if necessary, use water or a light coolant recommended for stone work to reduce dust and heat.
Usage recommendations
For best results with sandstone, operate at moderate speeds, apply light, consistent pressure, and wear appropriate dust protection. Avoid using this diamond burr on harder stones or metals to prevent premature wear.
