Diamond Ball Carbide Burr EXO PRO 1.4 mm – EXO

Diamond ball carbide burr EXO PRO 1.4 mm is a precision rotary tool head with a spherical diamond-coated tip designed for controlled grinding, shaping and fine finishing of hard materials. The 1.4 mm ball profile enables work in tight radii and confined areas, delivering consistent results on ceramics, glass, stone and hardened metals. The burr is compatible with standard rotary tools and micro-motors used in jewelry making, dental laboratory tasks, model making and other applications requiring high-precision material removal and surface preparation.

Advantages

The diamond coating on the ball-shaped head ensures durable cutting performance and effective abrasion on brittle and hard substrates. The small 1.4 mm diameter provides high accuracy for detailed contours and internal radii. Carbide core construction gives shaft stability and resistance to bending under rotary loads, while the EXO PRO design supports consistent balance and reduced vibration during use.

Suitable for

• Precision grinding and contouring of ceramics and glass
• Fine shaping and finishing of stone and gemstones
• Detail work in jewelry making and metal microfabrication
• Dental laboratory trimming, shaping and surface preparation
• Model making and restoration tasks requiring small-radius detailing

Key specifications

• Tip shape: spherical (ball) with 1.4 mm diameter
• Abrasive: industrial diamond coating
• Core material: carbide shaft for rigidity
• Intended tool type: rotary tools and micro-motors
• Primary applications: grinding, shaping, finishing of hard and brittle materials

How to use

Install the burr into the collet or chuck of a compatible rotary tool or micro-motor, ensuring a secure fit and correct runout. Select an appropriate rotational speed for the material — lower speeds for fragile glass and ceramics, higher speeds for hardened metals — and apply light, controlled pressure to avoid overheating and excessive material removal. Use steady, even strokes and maintain coolant or air flow where appropriate to remove debris and reduce temperature build-up. Periodically inspect the burr for wear and replace when cutting efficiency decreases.

Usage recommendations

Wear appropriate eye and respiratory protection when working with dust-producing materials. For best results, pair the 1.4 mm diamond ball burr with a steady hand and magnification for micro-detail work; use water or air cooling when machining heat-sensitive substrates. Avoid aggressive side loading to extend burr life.
