Bordo 12pce 1.0 - 6.5 x 0.5mm Black Knight M2 HSS Jobber Set - ABS Case 2003-M1

Features:

• Bordo Metric 12 Piece Black Knight M2-HSS Twist Drill Set in ABS Plastic Case
• 1.0-6.5mm x 0.5mm rises
• 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.
