Diamond Burr Bit EXO PRO 1.8 mm — EXO

Diamond burr bit EXO PRO 1.8 mm is a rotary tool accessory with a spherical diamond-coated head designed for precision grinding, shaping and finishing of hard materials. The 1.8 mm ball profile and diamond abrasive surface provide controlled material removal and repeatable results when working on ceramics, glass, stone, hard composites and artificial or natural nails. The bit is intended for detailed work where a small radius and fine control are required.

Advantages

The diamond-coated spherical tip offers long-lasting abrasive performance and consistent cutting action on brittle and hard substrates. Its compact 1.8 mm working diameter enables access to tight areas and precise contours while producing minimal chipping when used with appropriate speed and technique. The rigid construction ensures stability during rotation for accurate shaping and finishing.

Suitable for

• Precision grinding and shaping of ceramics and porcelain
• Detail work and edge refinement on glass and stone
• Fine contouring and smoothing of hard composite materials
• Manicure and pedicure procedures requiring small spherical burrs for cuticle and nail surface work
• Model making and small-scale hobby machining

Key specifications

• Head shape: spherical (ball)
• Working head diameter: 1.8 mm
• Abrasive type: diamond coating
• Intended tool type: rotary tools and handpieces compatible with standard shanks
• Typical applications: grinding, shaping, deburring, finishing

How to use

Fit the burr into a compatible rotary tool or handpiece and secure according to the tool manufacturer’s instructions. Select an appropriate rotational speed for the material—lower speeds for hard brittle materials to reduce thermal stress and higher speeds for resilient composites where safe. Apply light, steady pressure and use controlled, sweeping passes rather than prolonged contact in one spot to avoid overheating and excess wear. Use water or air cooling when working on heat-sensitive substrates to preserve the abrasive and the workpiece.

Usage recommendations

Inspect the bit before each use and replace it if the diamond coating is excessively worn. Match the rotational speed and feed rate to the material to maximize life and minimize chipping. For manicure applications, follow hygiene and sterilization protocols specified for salon tools.
