Diamond core drill bit set M14 6, 8, 10, 12mm adapter M14/HEX max 12000 rpm 5pcs MN-76-290

Diamond hole saw set for precision drilling

The MN-76-290 diamond hole saw set is a complete tool designed for precision drilling of holes in very hard finishing materials. Four hole saws with diameters of 6, 8, 10 and 12 mm enable the creation of various mounting holes in porcelain stoneware, marble, granite, and glass.

Each hole saw is equipped with diamond cutting material and a special cooling wax located inside the body. During the drilling process, the wax melts and effectively cools the diamond working part, which prevents the tool from overheating and significantly extends its service life.

Advanced Vacuum Brazed technology

The construction is based on Vacuum Brazed technology, which ensures a strong and clean bond between the diamonds and the steel body. This production method guarantees high resistance to high temperatures and friction during operation.

The body of each hole saw is made of durable special steel that does not crack even when drilling with small diameters. Thanks to this, the tool maintains its structural integrity over a long period of operation.

Universal tool compatibility

The M14 thread allows for direct mounting on most angle grinders available on the market. The set also includes a practical M14/HEX adapter, allowing the hole saws to be mounted in hexagonal (HEX) spindles, which expands the application possibilities to include drill-drivers and standard drills.

A maximum rotational speed of 12000 rpm allows for effective work with most power tools available on the market.

Precision workmanship without material damage

Vacuum Brazed technology enables precise point drilling while maintaining the highest quality of hole edges. Each hole made is characterized by smooth edges without cracks, chips, or material breakage.

The high efficiency of the process results from the optimal bond of the diamond cutting material to the steel body. This solution allows for effective drilling through even the most demanding ceramic surfaces while maintaining full control over the processing procedure.

The set contains all the necessary elements to start work immediately: four hole saws of different diameters, a HEX/M14 adapter, and a practical plastic case for safe storage and transport of the tools.
