Sherwood HSS Ground Flute 'Select-A-Drill' Set, Metric - 19 Pieces
Sherwood Jobber drills are general-purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite.
Black tools are generally recommended for ferrous applications where the oxide layer aids chip flow, helps to dissipate heat by retaining some coolant on the tool surface and also helps to prevent the tool from staining.
