Diamond Milling Cutter EXO PRO by EXO, rounded cylinder, 2.3 mm working diameter

Diamond milling cutter EXO PRO by EXO, rounded cylinder, 2.3 mm working diameter is a precision rotary tool bit designed for controlled material removal and fine shaping on hard and brittle substrates. The rounded cylinder profile provides a consistent contact surface for contouring and finishing small radii, enabling accurate detail work in dental, jewelry and fine craft applications. The 2.3 mm working diameter makes this bit suitable for narrow channels, precise edge refinement and localized surface smoothing.

Advantages

This EXO PRO diamond milling cutter offers a durable diamond-coated surface that ensures consistent cutting performance and extended tool life when used on appropriate materials. The rounded cylinder geometry reduces the risk of sharp-corner gouging and allows smooth transitions on curved surfaces. Its compact working diameter and standardized shank compatibility allow easy installation in most rotary handpieces and micro-motors used for precision work.

Suitable for

• Fine contouring and finishing of hard materials
• Dental model work and laboratory shaping
• Jewelry detail work and stone setting preparation
• Micro-sculpting and precise craft or restoration tasks

Key specifications

• Working diameter: 2.3 mm
• Shape: rounded cylinder
• Coating: diamond abrasive surface
• Intended materials: hard and brittle substrates such as ceramics, glass, gemstones and hardened metals (where appropriate)
• Compatibility: standard rotary tool and micro-motor handpieces with matching shank size

How to use

Install the milling cutter securely in a compatible rotary handpiece or micro-motor, ensuring correct collet/clamping for concentric rotation. Operate at appropriate rotational speeds for the target material and apply light, steady pressure to avoid overheating or premature wear. Use intermittent contact and coolant or air flow where applicable to evacuate debris and reduce thermal loading. Follow safety procedures including eye protection and dust extraction when machining brittle materials.

Usage recommendations

For best results, select rotational speed and feed appropriate to the workpiece material: moderate to high speeds for non-metallic hard materials, and lower speeds with gentle passes for hardened metals. Periodically inspect the diamond surface for wear and replace the cutter when cutting efficiency declines. Avoid excessive lateral force to maintain profile accuracy and extend service life.
