Discover the new interchangeable head drilling system from Gühring: BT 800

Modular drill reduces set-up times and scrap.

With the BT 800, Gühring is launching a high-performance replaceable head drilling system with bayonet lock, which is particularly impressive in medium to large diameters from Ø 14mm due to its cost-effectiveness, flexibility and tool life.

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 BT 800 replaceable head drilling system, Gühring addresses precisely these points – and offers an economical and high-performance alternative to conventional solid carbide drills.

Modular system with solid carbide performance
The BT 800 combines two properties that are often mutually exclusive: The wear resistance of a solid carbide tool with the modular flexibility of a replaceable head system. This is made possible by the innovative bayonet interface – the centrepiece of the BT 800 – which stands for maximum clamping force, precision and repeat accuracy. Whether material change, component variation or process optimisation: 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 carrier.

Cost efficiency for large diameters
The system fully utilises its economic advantages, especially for diameters from Ø 14mm. Only the drill head is replaced when worn – this not only lowers tool costs, but also reduces warehousing and capital commitment.

Focus on productivity and flexibility
The option of combining different drill heads on one carrier shaft ensures a high degree of flexibility for changing requirements and materials. Heads can be changed quickly and safely – an advantage that reduces setup times and increases machine availability. Another plus point: Gühring offers a closed tool cycle for the BT 800, including regrinding (up to twice) and a recycling service. This not only reduces costs, but also conserves resources.

Programme and technical features
This modular system has been launched with two holders for the Ø range 16mm to 26mm for drilling depths of 3xD and 5xD. Narrowly stepped Ø steps, in 0.1mm increments, enable good guidance and increase the stability of the tool. The drill head with Persistum coating was specially developed for steel machining in the Ø range 16mm to 26mm. The range will be expanded in September 2025 with holder sizes 1.5xD, 8xD and 12xD as well as a Pilotier drill head with internal cooling for 4-fold cooling.
