Advantages

This diamond core drill bit offers exceptional cutting speed and durability when working with dense materials. The high-quality diamond segments are optimized for heat resistance and wear, ensuring that the tool maintains its sharpness over extended periods of use.

The precise 27.0 mm diameter ensures consistent hole sizing, which is critical for professional installations and structural work.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Working with natural stone and granite
• Masonry and brickwork applications
• Installation of plumbing or electrical fixtures

When it may not be suitable

This drill bit is not intended for use with soft materials like wood, plastic, or metal, as the diamond segments are specifically engineered for abrasive mineral-based surfaces. It is also not suitable for use with standard drill chucks, as it requires an M14 threaded spindle found on angle grinders.

Key specifications

• Diameter: 27.0 mm
• Connection type: M14 thread
• Material compatibility: Stone, tile, masonry
• Tool compatibility: Angle grinders

How to use

To use the Makita diamond core drill bit, securely attach it to the M14 spindle of your angle grinder. Ensure the tool is unplugged during installation. Position the bit at a slight angle against the surface to initiate the cut, then gradually straighten it as the groove forms. Maintain steady pressure and allow the diamond segments to do the work without forcing the tool. It is recommended to use a guide or template to ensure accurate placement.

What to consider before purchase

• Verify that your angle grinder features an M14 spindle connection.
• Ensure the 27.0 mm diameter meets your specific hole size requirements.
• Confirm the material you are drilling is compatible with diamond-tipped tools.

Usage recommendations

For optimal results and to extend the lifespan of the diamond segments, use a light water spray or cooling system during operation to prevent overheating. Always wear appropriate personal protective equipment, including safety glasses and a dust mask, when drilling into stone or masonry.
