Diamond core drill bit 12mm M14 max 12000 rpm MN-76-212

Precise drilling in the hardest finishing materials

The MN-76-212 diamond core drill is a professional tool designed for making 12mm diameter holes in very hard finishing materials. Thanks to the M14 thread, it works perfectly with angle grinders, offering a maximum rotational speed of up to 12000 rpm.

Advanced Vacuum Brazed technology

The key advantage of this tool is the use of Vacuum Brazed technology, which ensures exceptional durability and resistance to high temperatures. This process creates an extremely strong bond between the diamonds and the steel body, eliminating the risk of cracking even when working with small diameters.

Cooling wax placed inside the core drill melts during operation, effectively cooling the diamond working part and enabling efficient dry drilling. This solution eliminates the need for additional cooling fluids and significantly simplifies the work process.

Versatility of applications

The tool performs excellently when processing a wide range of materials - from standard glaze and porcelain stoneware to the hardest varieties of natural stone such as marble or granite. It also efficiently handles roof tiles and other construction materials requiring precise hole drilling.

Precise point drilling guarantees holes with perfectly smooth edges without cracks, chips, or material breakage. This feature is particularly valuable in finishing works where surface aesthetics are of key importance.

Operating parameters and compatibility

The core drill achieves a diamond segment height of 10mm with a total tool length of approximately 61mm. The working length is 35mm, allowing for the creation of holes with significant depth while maintaining guiding stability.

The body made of durable steel does not crack during operation even at small diameters, which translates to long-term tool life. The maximum rotational speed of up to 12000 rpm enables a fast work pace while maintaining full control over the drilling process.

The M14 thread ensures universal compatibility with most angle grinders available on the market, making this tool a practical solution for both professional renovation crews and DIY enthusiasts engaged in finishing works.
