The large waveform effect minimizes heat to the extreme, achieving outstanding cutting performance. 【Features】 ▶ No need for deburring ▶ Regrindable ▶ Hole accuracy is H6 or better as long as there is no runout ▶ Excellent straightness ▶ R-blade with a special R shape that disperses cutting resistance, reduces heat, further minimizes burrs (delamination), and extends lifespan ▶ Taper end mill that eliminates fine burrs (delamination) ▶ Reamer shape that finishes the hole sides beautifully ▶ Capable of drilling straight even with slightly bent pilot holes ▶ Jointly developed with the Fukui Prefectural Industrial Technology Center; patent obtained ▶ Awarded the Kansai Monozukuri Shin Selection 2014 If you have any other concerns regarding drills, please feel free to consult us anytime. We look forward to your inquiries.
