◆適用於自動車床。 Suitable for use on automatic lathes. ◆寬滑的溝槽、高螺旋的導角，可使切削冷卻液充分供應至鑽刃，降低切削產生之高熱度， 減少黏屑與附著刃的產生，防止塑性變形。 Wide chip space and high helix angle help coolant fluids reach to
the cutting edge, reduce heat and built-up edge, and prevent deformation. ◆可廣泛適用於抗張強度達1000N/mm2等鋼材、不鏽鋼、鑄鐵等加工。 Suitable for steel which tensile strength approx. 1000N/mm2, Stainless Steel and Cast Iron. ◆適用於直徑3倍以上的深孔加工。 Suitable for drilling depth up to 3 x D. ◆不建議使用在鎳鉻或類似的鋼材。 Not recommend to be used on Nickel-Chrome Steel and similar
materials.
