Cle-Line 1805 3/8 HSS Heavy-Duty Steam Oxide 135 Aircraft Extension Drill - Pkg Qty 6

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 high-speed steel. 135° split point prevents walking, which produces a better quality hole. For drilling into mild steels or soft metals, like aluminum, copper, brass, bronze and non-ferrous materials. Pack Of 12. 30 Day Warranty.

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.

Heavy duty construction and extra length to drill in a wide range of applications where extra reach is needed. Multiple lengths offered for popular drill diameters. Manufactured from high-speed steel. 118° K-Notched point. Black oxide finish provides increased wear resistance and added lubricity in ferrous materials to prevent galling. For drilling in carbon steel, alloy steel or cast iron. Used in long reach applications. Made In USA. 30 Day Warranty.

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. Black 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 6. 30 Day Warranty.
