Cle-Line 1803 9/32 HSS Heavy-Duty Steam Oxide 135 Aircraft Extension Drill - Pkg Qty 12

135° Split point is self-centering for reduced thrust and easier penetration. Manufactured from cobalt high-speed steel with heavy duty geometry. Left-hand helix is ideal for use in screw machines where machine spindle rotation is counter-clockwise. Superior rigidity in portable drilling. Straw oxide finish for less galling. Three flats on shank for sizes above 11/64" for tighter chucking and less slippage. For superior rigidity in maintenance applications in stainless steel, titanium, alloy and carbon steel, cast iron and hardened steel. 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 ...

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.

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.
