Diamond Burr Ball 1.6 mm EXO PRO by EXO — rotary tool accessory

Diamond Burr Ball 1.6 mm EXO PRO by EXO is a rotary tool accessory with a spherical head coated in industrial diamond grit. It is designed for precise grinding, shaping and finishing of hard and brittle materials. The small 1.6 mm ball profile provides controlled contact area for detailed work on edges, contours and small cavities when used with micro drills and handheld rotary tools.

Advantages

The diamond-coated ball offers high hardness and wear resistance, enabling consistent performance on glass, ceramics, stone and hardened metals. Its compact spherical shape provides stable, predictable material removal and fine surface finishing. The burr is compatible with standard rotary tool collets and suited for high-speed operation, delivering accurate results in tight or intricate areas.

Suitable for

• Detail grinding and shaping of small parts
• Deburring and chamfering edges on brittle materials
• Engraving and inlay work on glass and ceramics
• Removing material from stone, hardened steel and composites
• Cleaning and finishing cavities, grooves and recesses

Key specifications

• Spherical head diameter: 1.6 mm
• Abrasive: industrial diamond grit coating
• Intended tool type: rotary tools and micro drills
• Shape: ball (spherical)
• Typical use: grinding, shaping, engraving, deburring, finishing

How to use

Install the diamond burr into a compatible collet or chuck and ensure it is securely clamped before operation. Operate the rotary tool at appropriate speed for the workpiece material—moderate to high RPM for hard materials—and apply light, steady pressure to avoid excessive loading or overheating. Use coolant or intermittent operation when working on heat-sensitive materials to extend tool life. Maintain proper eye and respiratory protection while working with dust-generating materials.

Usage recommendations

Begin work at lower speeds to gauge material removal rates and gradually increase speed if required. Avoid side-loading the small spherical head; use the ball surface for controlled contact and allow the abrasive to do the cutting. Clean the burr with a stiff brush after use to remove debris and preserve cutting efficiency.
