ANSI Black Oxide Jobber Drill Bit 135° Split Point Twist Drill Straight Shank

Black Oxide: A black finish is achieved by steam tempering - a thermal process which imparts a non-metallic surface to the tool. This surface is porous and by absorbing lubricant, helps prevent rusting, reduces friction and cold welding, resulting in increased tool life. Steam tempered products can successfully be used at slightly increased machining rates or on more difficult to machine materials.

Features:

Descriptions:

• High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.
• Universal 135° point shape for drilling a wide selection of materials.
• Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
• Ground flutes provide fast chip removal to maximize accuracy and efficiency along the full working surface of the bit.
• Special multi-cut geometry with ply-cutting and lower friction to reach better performance of endurance and removal of chips. So its life is lengthened. It is stable made and can cut with high speed, and make the surface of materials smooth. It has exact diameter and can use after regrinding.
