Description

1.5mm Black HSS Twist Drill – 2Pk Clam
Bordo Black Knight M2-HSS Twist Drills.
DIN338
118º Split Point (crankshaft point)
Split point is self centering and reduces the need for end thrust.
Friction at workpiece is reduced.
118º point angles are ideal for use in materials such as mild steel and cast iron.
The 118º point creates easily controlled chips which are wide and thin.
Black Finish Twist Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating.
This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life.
Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.
