## Long description

Diamond milling cutter GEKO G37520 is a 20 mm diameter rotary tool accessory with an M14 threaded shank and grit 30 abrasive surface. It is intended for grinding, shaping and removing material from hard surfaces such as natural and engineered stone, concrete, terrazzo and ceramic tiles. The tool is compatible with angle grinders and other rotary machines that accept M14-mounted accessories and is designed to deliver steady cutting action and controlled material removal on tough substrates.
Advantages
The diamond-coated cutting edge and medium-coarse grit provide a balance between material removal rate and surface finish, allowing faster stock removal than fine grits while maintaining predictable control. The M14 shank ensures secure mounting in standard angle grinders and rotary tools. Durable diamond segments extend tool life when used on abrasive materials, and the compact 20 mm diameter enables work in confined areas and for detail shaping tasks.
Suitable for
Grinding and shaping stone and concrete edges
Profiling and smoothing ceramic and porcelain tile surfaces
Removing small amounts of material and leveling uneven spots
Detail work and finishing in tight or hard-to-reach areas
Key specifications
Cutting diameter: 20 mm
Shank type: threaded M14
Abrasive: diamond-coated surface
Grit size: 30 (medium-coarse)
Intended materials: stone, concrete, ceramics, terrazzo
How to use
Mount the milling cutter securely in an angle grinder or compatible rotary tool that accepts M14 threads. Ensure the tool is tightened according to the machine manufacturer's instructions and that the grinder is switched off and unplugged during fitting. Wear appropriate personal protective equipment including eye protection, dust mask and hearing protection. Start the machine at a moderate speed and bring the cutter to the workpiece with steady, even pressure, avoiding excessive force. Make multiple light passes rather than attempting to remove large amounts of material in a single pass to prolong tool life and maintain control.
Usage recommendations
Use water cooling or intermittent cutting when working on very hard or abrasive surfaces to reduce heat build-up. Inspect the cutter regularly for wear and replace it when diamonds are significantly worn or cutting performance declines. Follow the grinder manufacturer's safety guidelines and select appropriate rotational speed for the material and grit size.
