Diamond core drill bit 25mm M14 max 12000 rpm MN-76-225

Professional drilling tool for the hardest materials

The 25mm diameter diamond core drill bit with an M14 thread is a specialized tool designed for precision drilling in extremely hard finishing materials. Thanks to the application of advanced Vacuum Brazed technology, the tool ensures exceptional durability and efficiency even when working with the most demanding surfaces.

Construction and advanced technology

The core drill body is made of durable steel, which does not crack during drilling even with small diameters, guaranteeing a long tool life. A key element is the Vacuum Brazed technology, which creates an extremely durable bond between the diamonds and the steel body.

Vacuum Brazed technology ensures high drilling efficiency thanks to the durable bond of diamonds to the body.

Cooling system enabling dry work

The interior of the core drill is filled with a special wax, which functions as a cooling system during dry operation. During drilling, the wax melts and effectively cools the diamond working part, preventing overheating and loss of cutting properties.

This innovative system eliminates the need for cooling fluids, which significantly simplifies the drilling process and allows for work in various conditions without additional workstation preparation.

Wide spectrum of applications

The tool performs excellently when processing ceramics, stoneware, terracotta, marble, and granite. It is particularly recommended for porcelain stoneware and other high-hardness materials where traditional methods may lead to cracks or chipping.

Precise point drilling guarantees holes with perfectly smooth edges without cracks, chips, or breakage.

Compatibility with common equipment

The standard M14 thread ensures compatibility with most angle grinders available on the market. A maximum rotational speed of 12 000 rpm allows for efficient work with typical devices used by professionals and DIY enthusiasts.

These parameters allow for optimal utilization of the grinder's motor power while maintaining control over the drilling process and the quality of the resulting hole.
