Jobber Length Drills

Parabolic flute disperses chips away from the cutting edges more rapidly and increasing coolant flow. Exceptional for deep-hole drilling. Manufactured from high-speed steel. Aerospace-style 135° split point is self-centering, reducing walking. Faster penetration rates than conventional HSS heavy duty jobber drills. Bright finishes. For drilling in low carbon steel, soft alloy steel, non-ferrous materials and aluminum with TiCN as a modification. Made In USA. Pack Of 12. 30 Day Warranty.

Heavy-duty construction for drilling in tough, high-tensile and work-hardening materials under extreme operating conditions. Manufactured from cobalt high-speed steel, increasing hot hardness and extending drill wear life. 135° P3 split point is self-centering for reduced thrust and easier penetration. Sizes smaller than .0625" do not have split point. Metric sizes are manufactured to DIN 338 OAL and flute length specifications. Straw finish adds lubricity and easily identifies cobalt drills. For drilling in stainless steel, tool steel, alloy steel and titanium. Made In USA. Pack Of ...
