Diamond core drill bit 6mm M14 max 12000 rpm MN-76-206

Professional tool for processing the hardest materials

The 6 mm diameter diamond core drill with M14 thread is a specialized solution designed for precision drilling in the most demanding finishing materials. Thanks to Vacuum Brazed technology, it ensures a durable connection between the diamond segments and the tool body, resulting in high efficiency and long service life when working with ceramics, porcelain stoneware, terracotta, marble, and granite.

Construction and manufacturing technology

The total length of the tool is 60 mm, with a working segment height of 10 mm.

The M14 thread allows for mounting in standard angle grinders available on the market. The internal cooling system based on a special wax allows for efficient drilling without the need for additional material wetting - during operation, the wax melts and naturally cools the working segment.

Operating parameters and quality control

A maximum rotational speed of 12 000 rpm allows for a fast working pace while maintaining full control over the drilling process. The internal wax cooling system enables dry working - there is no need to use additional cooling fluids or to wet the material surface.

The precise 6 mm diameter guarantees a perfect fit for standard mounting hole dimensions for finishing elements. Each piece is individually packed in a practical blister, which facilitates product identification and protects the tool from damage during transport and storage.

Professional application

The tool performs excellently during the installation of decorative and functional elements on ceramic surfaces. In the case of porcelain stoneware with increased hardness, the core drill maintains stable performance without the risk of cracks or chipping.

Working with marble requires special care due to its crystalline structure. Vacuum Brazed technology minimizes the risk of damaging the delicate surface of the natural stone. Granite, as one of the hardest construction materials, does not pose a challenge for this core drill - the diamond segments maintain their effectiveness throughout the product's life cycle.

Technique for correct use

Before starting work, mount the core drill in an angle grinder with an M14 thread, ensuring the tool is properly tightened. Then, mark the drilling point and begin work with short applications.

Appropriate pressure is key to achieving clean edges without chipping. Too much pressure can cause segment overheating and deterioration of cutting quality, while too little pressure extends working time and can lead to an irregular hole path.
