Titan Usa SD91437 Reduced Shank Drill Bit 37/64 in Hss

Product Description

The TITAN USA SD91437 is a reduced shank twist drill bit engineered for drilling precise holes in metal, wood, and plastic. It features a 37/64-inch cutting diameter with a 1/2-inch reduced shank, allowing it to be chucked in standard 1/2-inch drill chucks even though the cutting diameter exceeds that size. The bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish and a 118-degree split point angle for accurate starting without a center punch. Overall length is 6 inches with a 3-inch flute length. This is a Series 625 bit suited for professional drilling applications.

This bit is appropriate for use in machine shops, fabrication facilities, and maintenance environments where reduced shank drill bits are needed to extend the range of a standard 1/2-inch chuck. It fits bench drill presses, drill motors, and milling machine setups. The 2-flute design provides efficient chip evacuation during drilling. Licensed machinists, millwrights, and maintenance mechanics commonly use this type of bit for production and repair work across light industrial and commercial settings.

Key Features

• 37/64-inch (0.5781 inch decimal) cutting diameter with 1/2-inch reduced shank for use in standard 1/2-inch chucks
• 118-degree drill point angle for general-purpose drilling across a range of materials
• High-speed steel construction for durability and heat resistance during extended use
• Bright/uncoated finish — no coating to flake or peel during regrinding
• 3-inch flute length and 6-inch overall length for drilling deeper holes with clearance
• 2-flute geometry promotes clean chip evacuation and consistent hole finish

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with any drill press, drill motor, or milling machine equipped with a standard 1/2-inch chuck capacity.

Installation Notes

Install and remove this bit only after the drill motor or drill press has been fully powered down and the chuck has stopped rotating. Secure the shank firmly in the chuck using a chuck key before beginning any drilling operation. High-speed steel bits are suitable for manual feed and moderate-speed machine feed applications — avoid excessive feed pressure, which can overheat the cutting edge. Proper cutting fluid or lubricant is recommended when drilling ferrous metals to extend bit life.
