Silver Conical Diamond Milling Bit M14 2-38mm

The Silver Conical Diamond Milling Bit M14 2-38mm is a specialized tool designed for precise shaping, enlarging, and smoothing holes in hard materials. Compatible with standard angle grinders via an M14 thread, this conical diamond bit provides reliable performance when working with tiles, gres, ceramics, and stone. It is engineered for professional construction, renovation, and tiling tasks, ensuring clean edges and high durability during intense operation.

Advantages

This diamond milling bit offers exceptional durability and wear resistance thanks to its high-quality diamond abrasive coating. The conical shape allows for versatile application, enabling users to easily adjust hole diameters, smooth rough edges, and bevel existing openings within a 2-38mm range. Designed for dry and wet operation with angle grinders, it delivers efficient material removal while maintaining precision and minimizing the risk of material cracking.

Suitable for

• Enlarging and shaping existing holes in ceramic tiles and gres
• Smoothing and beveling edges in porcelain, stone, and hard ceramics
• Professional tiling, bathroom renovations, and construction finishing work
• Adjusting pipe and drainage openings during installation

When it may not be suitable

This milling bit is not designed for drilling initial holes from scratch, as it functions primarily as a shaping and enlarging tool. It is also not suitable for use on soft materials such as wood, plastics, or soft metals, which can clog the diamond abrasive surface and reduce cutting efficiency.

Key specifications

• Conical diamond milling profile
• Working diameter range from 2mm to 38mm
• M14 thread connection for angle grinders
• Designed for hard materials including gres, ceramics, tiles, and stone

How to use

Attach the milling bit securely to an M14 threaded spindle of an angle grinder, ensuring it is tightened properly before operation. Start the tool and gently apply the conical surface to the edge of the hole that requires shaping or enlarging. Use smooth, circular motions and avoid applying excessive force to prevent overheating and premature wear of the diamond segments. Allow the tool speed to do the work, maintaining a steady angle for uniform results.

What to consider before purchase

• Verify that your power tool features a standard M14 spindle connection
• Assess the required hole size range to ensure it falls within the 2-38mm working capability
• Determine if the primary application involves hard materials like gres, tiles, or stone

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and respiratory protection, when working with hard stone and ceramics. Ensure proper ventilation or use water cooling if applicable to extend the lifespan of the diamond coating and reduce dust generation.
