TRIUMPH TWIST DRILL Triumph® 011520 T1C HSS Jobber Length Drill Bit, Cobalt, 5/16 in

• Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
• Oxide/gold finish provides a polished finish and prevents chip building, galling and welding on a workpiece. It is commonly used on low carbon, stainless steel and ferrous metals.
• Spiral flutes are constructed with a higher flute angle to remove chips more easily.
