Titan Usa SD91446 Reduced Shank Drill Bit 23/32 in Hss

Product Description

The TITAN USA SD91446 is a reduced shank twist drill bit designed for drilling through metal, wood, and general-purpose materials in trade and industrial applications. The bit measures 23/32 inch (0.7188 inch decimal) in cutting diameter with a 1/2 inch reduced shank, allowing it to be used in standard 1/2 inch chucks when the full cutting diameter would otherwise require a larger chuck. Constructed from high-speed steel (HSS), it features a 118-degree split-point angle and a bright, uncoated finish. Overall length is 6 inches with a 3 inch flute length. This is a Series 625 bit with two flutes and weighs 0.4 pounds.

This drill bit is suited for machinists, fabricators, pipefitters, and general trade professionals who need to drill larger-diameter holes using equipment with a standard 1/2 inch chuck capacity. The reduced shank design makes it practical for portable drills and drill presses that cannot accommodate a larger shank. Typical applications include metal fabrication shops, mechanical rooms, and job-site drilling in HVAC, plumbing, and electrical rough-in work where oversized pilot or clearance holes are required.

Key Features

• 23/32 inch cutting diameter (0.7188 inch decimal) with a reduced 1/2 inch shank for standard chuck compatibility
• High-speed steel construction provides durability across metal, wood, and composite materials
• 118-degree drill point angle suited for general-purpose drilling applications
• Bright, uncoated finish — no coating to chip or flake during use
• 6 inch overall length with 3 inch flute length for adequate chip clearance in deeper holes
• Two-flute design balances material removal speed with bit rigidity

Compatibility

Designed as a general-purpose reduced shank drill bit for use in any 1/2 inch drill chuck, whether mounted in a portable drill, drill press, or milling machine. No specific equipment model compatibility was provided by the manufacturer for this part.

Installation Notes

Installation and use should be performed by a qualified machinist, fabricator, or trade professional familiar with drill press and portable drill operation. Secure the workpiece firmly before drilling and verify the chuck is tightened completely around the reduced shank before starting the tool. Use appropriate cutting fluid or lubrication when drilling hardened or thick metal stock to extend bit life and reduce heat buildup. Always wear appropriate eye protection and follow applicable OSHA and shop-safety guidelines when operating rotary cutting tools.
