Features: 8.4mm Black HSS Twist Drill; Bordo Black Knight M2-HSS Twist Drills. ; DIN338; 118 Split Point (crankshaft point); Split point is self centering and reduces the need for end thrust. ; Friction at workpiece is reduced.; 118 point angles are ideal for use in materials such as mild steel and cast iron. ; The 118 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. ; Specifications:Diameter (mm) 8.4Flute Length (mm) 75Overall Length (mm) 117
