7/16" Cobalt Drill Bit
This fractional-inch jobber bit is made from cobalt steel with a straw-bronze finish. The split-point tip is designed to start on contact and reduce wandering. It suits mechanics and fabricators drilling hard metals such as stainless steel. The 3/8 inch shank fits standard drill chucks.
Sustained drilling performance
Cobalt steel retains hardness at elevated temperatures better than high-speed steel. The 143-degree point angle and split-point geometry help maintain cutting efficiency during repeated holes. Right-hand cutting direction clears chips through the 4-1/16 inch flute length. The bit is built for continuous use in tough alloys without rapid edge breakdown.
Heat, noise and power draw
Cobalt construction dissipates heat generated during prolonged metal drilling. No internal coolant channel is present, so external lubrication is recommended for deep cuts. The split point lowers thrust force, reducing motor load and vibration on the power tool. California Proposition 65 warning applies due to regulated chemical content.

Questions about this item
How much heat does the 7/16" cobalt steel bit generate when drilling all day?
Cobalt steel resists heat better than standard high-speed steel, and the 143-degree split point reduces thrust, keeping the bit cooler during extended use.
What chuck size do I need to run the 3/8" shank on my drill?
A 3/8-inch or larger drill chuck is required to hold the 3/8-inch shank diameter securely.
Will the 5-1/2" overall length fit my older right-angle drill attachment?
The 5-1/2-inch overall length and 4-1/16-inch flute length fit most standard right-angle attachments designed for jobber-length bits.
