Great for drilling extremely deep holes and reaching places which cannot be reached by the long series drill.Longer flute and overall length than long series drills.Come with a black surface finish for extra strength.
A black finish achieved by a 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.
