Diamond Milling Bit EXO PRO 1.4 mm Cylinder — EXO

Diamond milling bit EXO PRO 1.4 mm Cylinder is a precision rotary tool designed for controlled material removal and fine surface finishing. Manufactured by EXO, this rigid diamond-coated cylinder head delivers consistent performance on hard and brittle materials. The 1.4 mm working diameter and cylindrical profile enable narrow, straight cuts and even shaping for tasks that require accuracy and minimal material loss.

Advantages

The diamond coating ensures high wear resistance and stable cutting action on a range of hard substrates. The cylindrical head profile provides a predictable contact area for uniform smoothing and edge work. Its small 1.4 mm diameter allows for detailed operations in confined areas while maintaining dimensional stability. The rigid construction reduces vibration for improved control and repeatable results.

Suitable for

• Precision manicure and pedicure shaping and surface finishing
• Jewelry making: fine detailing, stone seat preparation and adjustment
• Model making and scale work requiring small, accurate cuts
• Light industrial deburring, chamfering and spot surface correction on hard materials

Key specifications

• Head shape: cylindrical
• Working diameter: 1.4 mm
• Abrasive type: diamond coating
• Intended use: fine shaping, smoothing and surface detailing
• Construction: rigid rotary tool for low-vibration operation

How to use

Mount the diamond milling bit into a compatible collet or chuck sized for the bit shank. Operate the rotary tool at moderate to high speed as recommended by the tool manufacturer; adjust speed based on the material hardness and required finish. Use light, steady pressure and move the bit with controlled passes to avoid overheating or excessive material removal. Allow the abrasive to do the cutting and avoid forcing the bit into the workpiece.

Usage recommendations

For best results, use with appropriate personal protective equipment (eye protection and dust extraction). Periodically inspect the bit for wear and replace when cutting efficiency decreases. When working on heat-sensitive materials, reduce speed and use intermittent passes to limit heat buildup.
