Cle-Line 1805 1/4-E HSS Heavy-Duty Steam Oxide 135 Aircraft Extension Drill - Pkg Qty 12

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.

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 6. 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 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.

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 12. 30 Day Warranty.
