For trouble-free and process-reliable deep-hole drilling up to 50×D. The individual tools are perfectly matched in respect of geometries, the tolerances of the cutters and the point angles.
Within the production process this system ensures a seamless switch from one tool to the other. The proven colour rings are an additional aid for the selection of the right tool.
A system for highest precision
Exact deep-hole drilling is a challenge. With the GARANT deep-hole drilling system these problems can be solved in a process-reliable way.
1. NC spotting drill - The right start: Reliable even for difficult machining requirements – the GARANT deep-hole drilling system. Start by spot drilling (especially for horizontal machining) for exact location and alignment accuracy.
2. The pilot drill will set the direction: The pilot drill will generate a bore 6×D – the ideal preparation for deep-hole drilling. Important: Following this, especially for horizontal machining, generate a countersink.
3. The co-pilot drill will clear the way: Basically alreay a deep-hole drill, the co-pilot drill will generate a precise 20×D bore (necessary for deep-hole drill 40×D / 50×D).
4. The final deep-hole drilling step: Precision right to the very end – the GARANT deep-hole drill guarantees a reliable and trouble-free completion of the total process (50xD).
