33022 Micro Grain Solid Carbide General Spade Drill Bit, Uncoated (Bright) Finish, Round Shank, Straight Flute, 118 Degrees Point, 5/16" Size, 2-1/2" Length (Pack of 1)

Cobra Carbide general spade drill bit is manufactured from premium sub micron grain carbide. Ideal for drilling thin sheet materials. Designed for shallow hole drilling, do not exceed two diameter deep. Heavy duty web reduces breakage. Can also be used for spot drilling. Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Tolerance: Good for hardened steel, nickel/inconel alloy, stainless steel; excellent for aluminum alloy, carbon steel, alloy steel, cast iron. Tolerance: H6 - shank diameter; H7 - cut diameter.

• Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems
• Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications
• Round shanks allow use with a wide variety of toolholding systems
• Straight flute drill bits are well suited for drilling in hard materials and are also well-suite to drilling in lathe applications
• Designed for shallow hole drilling, do not exceed two diameter deep
