4.05mm HSS S/S Jobber Drill

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 Typical Applications Cutting and drilling Ferrous materials Steel Iron Nickel Brass Aluminium alloy Graphite Notes Available in sizes 0.25mm -20.00mm Standards Manufactured to BS 328/DIN338RN
