The J100 Series are general purpose HSS straight shank drills with a black oxide finish. Ideal for applications involving steel (including cast steel) cast iron (including malleable cast iron) as well as nickel, brass aluminium alloys and graphite. Their 118° point allows for precise hole alignment and reliable cutting performance whilst the black oxide coating helps reduce heat by retaining coolant on the tool surface. The coating also helps reduce the risk of the tool staining.
Features and Benefits • High speed steel construction for increased tool durability • Point angle of 118° for precise holemaking and precision cutting • Black oxide coating helps aid chip flow, reduce heat and prevent staining • Ideal for applications involving steel, iron, nickel, brass, aluminium alloy and graphite
Insert Grade QX5030 (ISO P20-P40 M20-M30) CVD Coated. - Medium / rough turning and intermediate cutting of steel / stainless steel. Combination of toughest substrate and alumina coating (MT-TiCN + TiC + AL2O3 + TiN) having superior chipping resistance provide wide coverage.
