  • RS thinning is adopted for ø0.5 mm and larger sizes.

It is a solid carbide drill bit that can be used for various purposes such as high efficiency of counter boring and drilling on inclined surfaces and curved surfaces.
[Features]
・ It supports high efficiency counter boring, drilling on non-planar surfaces such as inclined surfaces and cylindrical surfaces, and intermittent drilling. Also effective in suppressing burr on the outlet side.
・ It realizes high rigidity by adopting RS thinning with thick bottom.
・ Wide cutting chip pocket and high-quality rake face shape provide excellent cutting chip discharge performance.
・ It achieves high cutting edge strength with ideal cutting edge design.
・ It supports machining of overhang length L/D = 10.
・ It supports internal refueling. It realizes deeper hole processing.
