High-performance wet drill bit Drill master Ø 10 mm, art.-no. 50442

Diamond core drill bit for precise drilling in hard materials

A high-quality diamond core drill bit is the first choice when it comes to clean and controlled drilling in demanding materials. Especially when working with tiles, natural stone and porcelain stoneware, maximum precision, low vibration and reliable cooling are essential. Professional diamond core drill bits deliver precise results even with high material hardness and delicate surfaces.

Thanks to the industrially applied diamond coating, diamond core drill bits cut efficiently while protecting the material. When combined with wet drilling technology, the generated heat is dissipated in a controlled manner, reducing stress cracks and significantly increasing tool service life. The result is smooth drill edges without chipping – even when drilling close to the edge.

Versatile applications for trades & installation

Diamond core drill bits are used wherever precision is required: in tiling, sanitary and installation work, as well as for interior construction and mounting tasks. Depending on the diameter, they are suitable for small dowel holes as well as larger openings for pipes or fittings. Thanks to common connection types, diamond core drill bits can be flexibly combined with angle grinders, drilling machines or cordless tools.

Long service life through proper care of the diamond core drill bit

To maintain consistently high cutting performance, it is recommended to sharpen a diamond core drill bit regularly. Special sharpening stones, such as our diamond sharpening stone (Art. No. 20050), reactivate the diamond coating, improve cutting speed and significantly extend the tool’s service life.

Conclusion:

With a professional diamond core drill bit, you choose precision, reliability and clean drilling results – the ideal solution for anyone who needs to work accurately and safely in hard materials.
