## Long description

The Makita D-79924 Diamond Core Bit is a professional-grade drilling accessory engineered for precision and longevity when working with demanding materials. With an 8mm diameter and a standard M14 connection, this core bit is specifically designed to integrate seamlessly with angle grinders, providing the stability and power required for clean, chip-free holes in various hard surfaces.
Advantages
This diamond core bit offers exceptional durability due to its high-quality diamond grit composition, which maintains its cutting efficiency over extended periods of use. The M14 connection ensures a secure and vibration-free fit on standard angle grinders, allowing for better control and accuracy during the drilling process. Its design minimizes material breakage, ensuring that tiles and stone surfaces remain intact and aesthetically pleasing after the hole is drilled.
Suitable for
Drilling holes in ceramic and porcelain tiles
Working with natural stone and granite
Renovation projects requiring precise cable or pipe routing
Professional construction and interior finishing tasks
When it may not be suitable
This core bit is not intended for drilling through metal, wood, or concrete with heavy reinforcement. It is specifically optimized for rotary action on angle grinders and should not be used in hammer drill mode, as this will damage the diamond segments.
Key specifications
Diameter: 8 mm
Connection type: M14
Compatible tools: Angle grinders
Material application: Tile, stone, ceramics
How to use
To use the Makita D-79924, securely attach the bit to the spindle of your angle grinder, ensuring it is tightened properly. Start the drilling process at a slight angle to create a starting groove, then gradually straighten the tool to a perpendicular position while maintaining steady pressure. Use a circular motion to assist with dust removal and cooling during the operation.
What to consider before purchase
Verify that your angle grinder supports the M14 connection standard.
Ensure the material thickness does not exceed the effective cutting depth of the bit.
Consider using a water cooling system if drilling through particularly dense or thick stone to extend the life of the diamond segments.
Usage recommendations
Always wear appropriate personal protective equipment, including safety glasses and a dust mask, when operating power tools. Allow the tool to cool down periodically during intensive drilling sessions to prevent overheating and premature wear of the diamond edge.
