Titan Usa SD93664 Reduced Shank Drill Bit 1 in Cobalt

Product Description

The TITAN USA SD93664 is a cobalt reduced shank drill bit engineered for drilling hard and abrasive materials in demanding trade and industrial applications. It features a 1 inch cutting diameter with a 1/2 inch reduced shank, allowing it to be chucked in standard 1/2 inch drill presses and magnetic drills without requiring a larger spindle capacity. The 135-degree split point angle promotes self-centering and reduces walking on entry, minimizing the need for a center punch. Overall length is 6 inches with a 3-inch flute length and a bright, uncoated finish. This Series 622 bit is suited for metalworking professionals and machinists who need reliable performance in tough stock.

This drill bit is designed for use in metal fabrication, mechanical contracting, and industrial maintenance environments. The cobalt construction provides heat resistance during high-speed or high-feed drilling into stainless steel, hardened alloys, cast iron, and similarly difficult materials. The reduced shank design makes it practical for shops and field technicians who are working with standard 1/2 inch capacity chucks but need to bore larger-diameter holes without upgrading to a larger drill press or dedicated tooling. Two flutes provide efficient chip evacuation during deep-hole operations.

Key Features

• 1 inch cutting diameter with 1/2 inch reduced shank for use in standard chucks
• Cobalt tool material for heat resistance and durability in hard metals
• 135-degree split point angle for self-centering entry without center punch
• 6-inch overall length with 3-inch flute length for adequate reach and chip clearance
• Bright, uncoated finish — Series 622, 2-flute configuration

Compatibility

Designed as an OEM-style replacement or direct-use reduced shank drill bit compatible with standard 1/2 inch keyed and keyless drill chucks on drill presses, magnetic base drills, and portable power drills.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the reduced shank fully in the chuck and verify concentricity before operation. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before drilling. Consult applicable shop safety standards and equipment manufacturer guidelines for recommended spindle speeds based on material type and bit diameter.
