Titan Usa SD93637 Cobalt Drill Bit 37/64 in 1/2 in Shank

Product Description

The TITAN USA SD93637 is a reduced shank cobalt drill bit designed for drilling through tough materials including hardened steels, stainless steel, and cast iron. It measures 37/64 inch (0.5781 inch decimal) in cutting diameter with a 1/2 inch reduced shank, allowing it to chuck into standard 1/2 inch drill chucks while cutting a larger hole diameter. The 135-degree split point angle reduces walking at startup and requires less feed pressure than a conventional 118-degree point. Overall length is 6 inches with a 3-inch flute length. The bright, uncoated finish is suited for use with cutting fluids. This bit is used by machinists, pipefitters, ironworkers, and maintenance trades working with ferrous and high-alloy metals.

The SD93637 fits applications where a drill press, magnetic drill, or heavy-duty corded drill is used on structural steel, stainless fabrications, or hard plate. The reduced shank design makes a 37/64 inch diameter cut accessible through a standard 1/2 inch chuck without requiring a larger drill motor. It is part of the TITAN USA Series 622 cobalt drill bit line. Typical use cases include field drilling, shop fabrication, and maintenance repair operations where cobalt tooling is required to handle work-hardening alloys or abrasive materials that would rapidly dull high-speed steel bits.

Key Features

• Cobalt tool material provides heat and wear resistance for drilling hard and stainless steels
• 135-degree split point reduces drill walking and lowers required feed force
• Reduced 1/2 inch shank allows use in standard 1/2 inch chucks for a 37/64 inch cut diameter
• Bright uncoated finish compatible with cutting oils and water-soluble coolants
• 2-flute design clears chips efficiently during deep-hole drilling
• Series 622 construction — 6 inch overall length with 3 inch flute length

Compatibility

Designed as a direct-fit Series 622 cobalt reduced shank drill bit for use in any 1/2 inch keyed or keyless drill chuck on drill presses, magnetic base drills, or handheld drill motors rated for 1/2 inch shank tooling.

Installation Notes

This bit is installed and operated by machinists, pipefitters, ironworkers, or qualified maintenance technicians familiar with metal cutting operations. Secure the reduced shank fully into the chuck jaws before drilling and verify the chuck is tightened at all three key positions on keyed chucks. Always use an appropriate cutting fluid when drilling stainless or hardened steels to extend bit life and reduce heat buildup. Wear appropriate eye and hand protection in accordance with applicable shop safety standards.
