Diamond Conical Cutter GEKO M14, diameter 20–48 mm, grit 100

Diamond Conical Cutter GEKO M14, diameter 20–48 mm, grit 100 is a diamond-coated conical grinding and cutting tool designed for use with standard M14 angle grinders and compatible rotary tools. It is intended for shaping, trimming and smoothing hard materials including natural stone, concrete, masonry and glazed ceramics. The conical profile allows access to edges, corners and curved surfaces while the medium-fine grit 100 provides balanced material removal and surface finish.

Advantages

The diamond coating ensures durable cutting edges and consistent performance on abrasive materials. The conical shape offers precise control when working on profiles, grooves and contours. The M14 threaded shank provides secure mounting in commonly used power tools and enables quick replacement. Grit 100 achieves a compromise between cutting speed and surface quality, reducing the need for repeated passes while preserving detail.

Suitable for

• Shaping and trimming natural stone and marble
• Grinding and profiling concrete edges and joints
• Removing excess material from ceramic and porcelain surfaces
• Detail work on masonry, tiles and restoration tasks

Key specifications

• Tool shape: conical
• Suitable shank type: M14 threaded
• Working diameter range: 20–48 mm
• Abrasive type: diamond-coated
• Abrasive grit: 100 (medium-fine)
• Typical applications: cutting, shaping, grinding, profiling

How to use

Fit the cutter to an angle grinder or rotary tool with an M14 threaded spindle and ensure the tool is secured according to the power tool manufacturer’s instructions. Start at low speed to check the cutter’s position, then increase to the recommended operating speed for the material. Apply steady, light pressure and move the cutter along the work surface in smooth passes; avoid forcing the tool to prevent overheating and premature wear. Allow the diamond grit to do the work and periodically cool or clean the cutter if dust or slurry builds up.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask/respirator and hearing protection. For wet grinding applications, follow the tool and machine guidelines for water use to extend tool life and reduce dust. Inspect the cutter before use for even diamond coverage and replace it when cutting efficiency or surface quality declines.
