Titan Usa CD50246 Cobalt Jobber Drill Bit No. 46

Product Description

The TITAN USA CD50246 is a cobalt jobber-length drill bit sized to wire gauge No. 46, equivalent to 0.0810 inches in diameter. Built from cobalt high-speed steel and finished with an oxide/gold coating, this bit is engineered for drilling into tough materials where standard HSS tooling loses its edge prematurely. The 135-degree split point reduces walking on entry and lowers the thrust force needed to break through hard substrates. With an overall length of 2.125 inches and a 1.125-inch flute length, it fits standard drill chucks and collet holders with a straight cylindrical shank. Machinists, tool-and-die workers, and fabrication shops reach for this bit when working with demanding materials that demand a more durable cutting edge.

This bit is designed for drilling stainless steel, superalloys, and titanium — materials that generate significant heat and rapidly degrade standard tooling. It suits use in manual drill presses, CNC machining centers, and hand-held power drills when proper feed rates and cutting fluid are applied. The 14xD flute-to-diameter ratio supports efficient chip evacuation over the full 1.125-inch maximum drilling depth. It ships as a single unit, making it practical to stock individually or in small quantities for production or maintenance applications.

Key Features

• Cobalt high-speed steel construction resists heat buildup when cutting stainless steel, superalloys, and titanium
• 135-degree split point reduces drill walk and lowers feed pressure on entry
• Oxide/gold coating provides additional surface hardness and lubricity
• Right-hand cut, 2-flute spiral configuration for efficient chip removal
• Straight cylindrical shank fits standard drill chucks and collet systems without modification
• 14xD flute-to-diameter ratio supports full-depth chip evacuation up to 1.125 inches

Compatibility

Designed as an OEM-style replacement and standard jobber drill for applications requiring a No. 46 wire gauge diameter hole in hard metals including stainless steel, superalloys, and titanium.

Installation Notes

Installation of this bit requires a drill chuck or collet rated for the 0.0810-inch shank diameter. Always secure the workpiece firmly before drilling and apply appropriate cutting fluid to extend tool life and reduce heat when working stainless or superalloy materials. Inspect the cutting edges for wear before each use; cobalt bits can chip rather than dull gradually under excessive feed pressure or improper speeds. Follow the tooling manufacturer's recommended speeds and feeds for the specific workpiece material.
