Product Description

[Features]
·Unique cutting edge shape enables drilling of various work materials such as stainless steel and aluminum alloy
·Drilling is possible under cutting conditions of 60 m/min or more
·Compatible with various applications such as hole finishing and high-precision thread pilot hole drilling
·It can be used for hole finishing because it achieves the same dimensional accuracy and surface roughness accuracy as boring and reaming
·Ideal for pilot hole drilling of high-precision thread with high percentage of thread engagement
·Possesses the ability to correct variations in pilot hole diameters, enabling improved hole position accuracy

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.
