Diamond Cone Burr EXO PRO 1.2 mm – EXO professional rotary tool bit

Diamond Cone Burr EXO PRO 1.2 mm is a precision rotary tool bit designed for controlled material removal and finishing on hard surfaces. The tool features an electroplated diamond abrasive on a conical head with a 1.2 mm tip diameter that enables fine-detail work and narrow access shaping. It is intended for use with rotary tools in hobby, craft and professional environments for tasks that require abrasion, shaping and deburring of brittle or hardened materials.

Advantages

The electroplated diamond surface provides consistent abrasive action and long wear life on ceramics, glass, stone and hardened metals. The cone profile with a 1.2 mm tip allows accurate, fine-detail shaping and access into tight areas. Its robust construction maintains form under repeated use and is compatible with standard rotary tool chucks for straightforward mounting and replacement.

Suitable for

• Detailing and engraving on ceramics and glass
• Shaping and smoothing stone and mineral specimens
• Deburring and removing small burrs from hardened metal parts
• Precision work in jewellery making, model building and fine crafts
• Fine grinding and contouring in workshop repairs

Key specifications

• Tip diameter: 1.2 mm (conical head)
• Abrasive type: electroplated diamond surface
• Profile: cone (for narrow access and detail work)
• Intended materials: ceramics, glass, stone, hardened metals
• Compatibility: for use with standard rotary tools and chucks

How to use

Install the diamond cone burr in the rotary tool chuck and tighten according to the tool manufacturer’s instructions. Select an appropriate rotational speed for the workpiece material—moderate to high speed for ceramics and glass, lower speeds for precise metal deburring—to avoid overheating. Apply light, steady pressure and use controlled passes; let the abrasive do the work rather than forcing the bit. Use appropriate coolant or intermittent contact when working on heat-sensitive materials to prevent thermal damage.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection, dust mask and gloves. Secure the workpiece and work in a well-ventilated area or use local extraction when producing dust. Inspect the burr regularly for wear and replace when abrasive performance declines to maintain precision and safety.
