Double Ended Drills

Heavy-duty construction for drilling in tougher materials. Manufactured from high-speed steel. 135° P3 split point is self-centering for reduced thrust and easier penetration. Sizes smaller than .0625" do not have split point. Three flats on the shanks on sizes 3/16" and larger for tighter chucking. Black and gold oxide surface finish increases wear resistance and adds lubricity, improving chip flow. For drilling in stainless steel, tool steel, alloy steel and cast iron. 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 ...

TiN (Titanium Nitride)-Tipped drills increases lubricity and heat resistant. Same benefits of TiN (Titanium Nitride) coated at a fraction of the cost. Manufactured from cobalt high-speed steel. 135° split point prevents walking, which produces a better quality hole. Sizes smaller than 1/16" do not have a split point. For drilling into steel, cast steel, alloyed and non-alloyed, grey cast iron, graphite and malleable cast iron. Pack Of 12. 30 Day Warranty.

Large size general-purpose drills with three-flatted 1/2" reduced shank. Manufactured from high-speed steel substrate. 118° split point for easier, more precise penetration. Standard 6" overall length and 3-1/8" flute length for increased rigidity, less deflection and better hole accuracy. Standardized lengths result in minimal adjustment during tool changes in screw machines and machining centers. Three flats on shank for a more positive grip in the drill chuck; flats reduce drill slippage under high loads. Ideal for portable drilling due to increased rigidity. Black and gold ...

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. TiN (Titanium Nitride) adds lubricity and hardness, enhancing chip flow, finished hole quality and drill life. For drilling in low carbon steel and soft alloy steel. Made In USA. Pack Of 6. 30 Day Warranty.
