1/8" DRILL BIT 9" LONG

KnKut Fractional Extra Length Drill Bits are gold surface treated and composed of a special Hi-Molybdenum tool steel. The gold surface treatment provides maximum lubricity and the Heavy-Duty construction, 135° split point requires no center punch and will not walk. For deep hole drilling, the gyroidal torsion flute and land construction works exceptionally. KnKut Extra Length Drill Bits are recommended for work hardening grades of stainless steel and other hard metals and will drill 12 or more diameters deep without having to clear chips. Feed rates may be twice that of standard drill bits.
