When it comes to cost per part, every single parameter counts: tool costs, setup times, and process reliability determine the efficiency of production. With the new changeable head drilling system BT 800, Gühring addresses exactly these points – offering an economical and high-performance alternative to conventional solid carbide drills.
Modular system with solid carbide performance
The BT 800 combines two properties that often exclude each other: the wear resistance of a solid carbide tool with the modular flexibility of a changeable head system. This is made possible by the innovative bayonet interface – the heart of the BT 800 – which stands for maximum clamping force, precision, and repeatability.
Whether material change, component variation, or process optimization: thanks to its modular design, the BT 800 can be quickly and easily adapted to different requirements – by changing the drill head directly in the machine without removing the holder.
Cost efficiency with large diameters
Especially with diameters starting from Ø 14 mm, the system fully exploits its economic advantages. Only the drill head is replaced in case of wear – this not only reduces tool costs but also simultaneously lowers inventory and capital commitment.
Productivity and flexibility in focus
The ability to combine different drill heads on a holder shaft provides high flexibility for changing requirements and materials. The head change is quick and safe – an advantage that shortens setup times and increases machine availability.
Another plus: Gühring offers a closed tool cycle for the BT 800, including regrinding (up to 2x) and recycling service. This not only reduces costs but also conserves resources.
Program and technical features
The market launch in June 2025 for this modular system will occur with two holders for the Ø range of 16.00 – 26.00 mm for drilling depths of 3xD and 5xD. Closely stepped Ø increments (in 0.1 mm steps) allow for good guidance and increase the stability of the tool. The drill head with Persistum coating has been specially developed for steel machining in the Ø range of 16.00 – 26.00 mm. The program will be expanded by September 2025 with holder sizes of 1.5xD, 8xD, and 12xD, as well as a pilot drill head with internal cooling for 4-fold cooling.
