Mechanics Length 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.

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 6. 30 Day Warranty.
