NS resin ball EM clear cut RSB230 R0.4X4

[Features]
3x flute length, 5x flute length, 10x flute length, super long neck, same diameter type, etc. can be selected according to the machining shape.
Also ideal for non-ferrous metals such as aluminum and copper.
It is a drill that corresponds to the pilot hole drilling of micro drills that use MUGEN MICRO COATING.
By adopting a thin coating exclusively for microdrills, it demonstrates excellent performance in drilling steel materials such as stainless steel.
Thinning is used at the tip to reduce cutting resistance and stabilize drilling accuracy. (φ0.025 or more)
