## Long description

The Makita D-44448 Diamond Core Bit is a professional-grade drilling accessory engineered for precision and longevity when working with demanding materials. With a 16mm diameter and a universal M14 connection, this core bit is specifically designed to be mounted directly onto angle grinders, providing a stable and efficient drilling experience. Its robust construction ensures consistent performance, allowing for clean and accurate holes in various hard surfaces without compromising the integrity of the material.
Advantages
This diamond core bit offers exceptional durability and heat resistance, which are critical factors when drilling into dense materials. The high-quality diamond grit ensures a fast cutting speed and a long service life, reducing the frequency of tool replacements. Because it is designed for use with angle grinders, it provides the user with excellent control and maneuverability, making it easier to achieve precise placement for every hole. The M14 connection ensures a secure fit, minimizing vibrations and enhancing overall safety during operation.
Suitable for
Drilling holes in ceramic and porcelain tiles
Working with natural stone and granite
Applications in masonry and brickwork
Renovation and construction projects requiring precise openings
This tool may not be suitable for drilling into reinforced concrete or extremely thick steel, as the diamond segments are optimized for stone and tile rather than heavy metal reinforcement. Additionally, it is not intended for use with standard drill drivers that lack the necessary M14 spindle interface or the high rotational speeds required for effective diamond core drilling.
Key specifications
Diameter: 16mm
Connection type: M14 thread
Compatible tools: Angle grinders
Material compatibility: Tile, stone, masonry
To use the Makita diamond core bit, ensure your angle grinder is unplugged or the battery is removed before installation. Screw the core bit firmly onto the M14 spindle of the angle grinder until it is hand-tight. When starting the drilling process, it is recommended to begin at a slight angle to establish a groove before gradually bringing the bit to a perpendicular position. Apply steady, moderate pressure and allow the diamond segments to do the cutting work without forcing the tool.
What to consider before purchase
Verify that your angle grinder features an M14 spindle connection
Ensure the 16mm diameter meets your specific project requirements
Check that the material you intend to drill is compatible with diamond core bits
For optimal results and to extend the life of the diamond segments, use a light water spray or cooling system if drilling through particularly hard stone. Always wear appropriate personal protective equipment, including safety glasses and respiratory protection, when performing drilling tasks.
