Titan Usa SD94747 Reduced Shank Drill Bit 47/64 in Hss

Product Description

The TITAN USA SD94747 is a reduced shank twist drill bit engineered for drilling applications that require a larger cutting diameter than the machine spindle or chuck capacity can accommodate directly. The bit measures 47/64 inch (0.7344 inch) in cutting diameter with a 1/2 inch reduced shank, allowing it to seat in standard 1/2 inch drill chucks and drill presses. Constructed from high-speed steel with a black oxide and straw finish, it provides moderate corrosion resistance and heat reduction during cutting. The 118-degree point angle is a general-purpose geometry suited for a wide range of ferrous and non-ferrous materials. Overall length is 6 inches with a 3 inch flute length.

This drill bit is suited for metalworking, mechanical, plumbing rough-in, and HVAC fabrication tasks where larger hole sizes are needed through sheet metal, structural steel, copper, aluminum, or similar materials. The reduced shank with three flats prevents slipping in the chuck during high-torque drilling operations. It is a practical choice for trade professionals who need a larger-diameter bit that still runs in a standard 1/2 inch capacity drill or drill press without requiring a dedicated large-capacity chuck.

Key Features

• 47/64 inch cutting diameter (0.7344 inch decimal) in a 1/2 inch reduced shank for use in standard chucks
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Black oxide and straw finish for moderate heat and corrosion resistance
• 118-degree point angle for general-purpose drilling geometry
• 3-flat reduced shank design prevents bit rotation in the chuck under load
• Series 623 — 6 inch overall length, 3 inch flute length

Compatibility

Designed as an OEM-style replacement or direct-use reduced shank drill bit compatible with any drill press, magnetic drill, or hand drill fitted with a 1/2 inch capacity chuck.

Installation Notes

Install in a 1/2 inch keyed or keyless chuck and tighten securely against all three flats to prevent slippage. Always power down and lock out the drill or drill press before changing bits. Use appropriate cutting fluid for ferrous metals to extend bit life and reduce heat buildup. Eye protection is required during all drilling operations per standard shop safety practice.
