Diamond Burr Cone 2.5 mm EXO PRO by EXO – rotary tool bit for precision grinding and shaping

EXO PRO Diamond Burr Cone 2.5 mm is a diamond-coated rotary tool bit engineered for precision grinding, shaping and deburring on hard surfaces. The cone-shaped head and 2.5 mm working diameter allow focused material removal and fine contouring in tight areas. The durable diamond abrasive is suitable for ceramics, glass, hard metals and natural stone, delivering consistent abrasion and long life in detailed tasks such as model making, jewellery work and small-scale restorations.

Advantages

The EXO PRO diamond cone burr combines a hard-wearing diamond-coated surface with a compact cone profile to provide precise control and uniform cutting action. Its small 2.5 mm diameter head enables access to narrow slots and fine edges, while the robust bonding of the abrasive resists wear during repetitive use on hard materials. The consistent grain distribution reduces chattering and helps maintain predictable material removal rates, which is useful for repeatable finishing and fitting tasks.

Suitable for

• Precision grinding and shaping of ceramics and glass
• Deburring and finishing of hardened metals and tool parts
• Stone and mosaic detail work
• Model making, jewellery and small decorative carving
• Maintenance and touch-up of cutting edges and small components

Key specifications

• Head shape: cone
• Working diameter: 2.5 mm
• Abrasive type: diamond-coated surface
• Typical applications: grinding, shaping, deburring, material removal
• Compatible with: standard rotary tools and die grinders with matching shank capacity

How to use

Install the diamond burr securely into the collet or chuck of your rotary tool, ensuring proper alignment and tight clamping. Operate the tool at appropriate speeds for the material being worked—typically moderate to high speeds for hard materials—while applying light, steady pressure. Use short, controlled passes and keep the burr moving to avoid heat buildup and uneven wear. Periodically stop to inspect the workpiece and remove debris from the burr surface with a brush or a dressing stick designed for diamond tools.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, a dust mask and hearing protection when working with hard materials. Select rotational speed based on material hardness and burr condition; reduce speed if excessive vibration occurs. Use coolant or intermittent contact when working on heat-sensitive substrates to extend tool life and maintain finish quality.
