Reduced Shank Drills

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.

Century's Black Oxide Drill bits are manufactured from industrial high speed steel surface treated for high performance and long life. M2 grade steel for drilling common steel flat bar angle iron tubing wood and plastic. No center punch needed Century 135° quick cut points are self centering and penetrate faster with less pressure. Will not walk or wander at the starting surface. 3/8" reduced shank. Manufactured from industrial high speed steel, surface treated for high performance and long life. M2 grade steel for drilling common steel (flat bar, angle iron, tubing), wood, and plastic. ...

135° Split point is self-centering for reduced thrust and easier penetration. Manufactured from high-speed steel substrate with heavy duty geometry. Black and gold (Barber pole) 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 low to medium carbon steel, alloy steel and cast iron.

Heavy-duty construction for drilling in tougher materials. Manufactured from premium 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.

HSS Taper Shank Drill Applications: General purpose HSS drills designed for drilling holes in a variety or normal steels, cast iron, and other ferrous and non-ferrous metals and alloys Suitable for a variety of drilling applications and conditions Taper shanks are sized by the standard Morse taper sizes To achieve optimal performance and extended tool life, suitable lubricating/cutting oils or appropriate coolant fluids are recommended for most drilling operations Available in a wide range of Diameters and Lengths Features: Right hand (clockwise rotation) cutting direction Standard two ...
