More Information


(1) Suitable for a wide range of workpieces
- With a uniquely shaped cutting edge, holes can be drilled in various work materials such as stainless steel, aluminum alloy, etc.
(2) High-speed cutting is now a reality
- Drilling is performed with 60 m or more cutting conditions per minute.
(3) Various uses including hole finishing and high-accuracy pilot holes
- Use for hole finishing to achieve a precision in dimensions / surface roughness that is equivalent to boring and reaming.
- Ideal for drilling high-accuracy pilot holes for screws with a high catch rate.
- Since a correction can be made for variations in the pilot hole diameter, the positional accuracy of the holes can be improved.
- When a shrink-fit holder is applied, further high-precision hole drilling can be achieved.
(4) Wet, semi-dry, and dry cutting are all handled
- Wet cutting using cutting fluid, as well as semi-dry and dry cutting are all supported.
