Metric - Black HSS Jobber Drill Set Bonus Stubbie Folding Knife

• 1.0-13.0mm 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 Jobber 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
