2000-3/64, 3/64″, Bordo Black Finish HSS Jobber Drill

Description

About this item:

• 3/64″ Black HSS Twist
• Bordo Black Knight M2-HSS Twist Drills.
• ANSI B94-11
• 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.
