Features of the NTBK DX HIGH SPEED Plus Core Bit

The Rothenberger NTBK DX HIGH SPEED Plus Core Bit (code FF44630) represents a professional solution for precision drilling in building materials. With a diameter of 30 mm and G1/2 connection, this diamond core bit is specifically designed to ensure superior performance in dry applications. The HIGH SPEED Plus design incorporates high-quality diamond segments that ensure optimal cutting speed while maintaining a long operating life.

Technology and materials

This diamond core bit is made with advanced technology that combines a hardened steel body with laser-welded diamond segments. The particular configuration of the diamond segments allows for rapid and precise cutting even on particularly hard materials. Laser welding ensures a secure connection between the segments and the core body, preventing detachment even in the most demanding working conditions.

Ideal applications

The NTBK DX HIGH SPEED Plus Core Bit is particularly suitable for:

• Dry drilling of ceramic tiles and porcelain stoneware
• Working on marble and natural stones
• Interventions on unreinforced concrete
• Drilling on bricks and hollow blocks
• Professional plumbing installations
• Installation of heating and air conditioning systems
• Creation of passages for electrical systems

Tips for optimal use

To obtain the best results with the NTBK DX HIGH SPEED Plus Core Bit, it is advisable to:

• Use the core bit with drills equipped with electronic speed regulation
• Start drilling at low speed to create the initial groove
• Gradually increase the speed once the cut has stabilized
• Apply moderate and constant pressure during drilling
• Take periodic breaks to avoid overheating the core bit
• Use a vacuum cleaner to remove dust during processing
• Periodically check the wear of the diamond segments

Maintenance and storage

To extend the life of the NTBK DX HIGH SPEED Plus Core Bit, it is important to clean it after each use, removing dust and debris from the diamond segments. It is advisable to store it in a dry environment protected from accidental impacts. Proper maintenance will ensure consistent performance over time and a lasting investment for industry professionals.
