Chicago-latrobe 46469 Cobalt Jobber Drill Bit 5 Mm

Product Description

The CHICAGO-LATROBE 46469 is a cobalt jobber length drill bit designed for high-performance drilling in hard and abrasive materials. Built to Series 550 standards, it features a 135-degree split point that reduces walking and lowers the thrust force needed to start a hole. The gold finish signals the cobalt steel construction, which retains hardness at elevated cutting temperatures. At 3.386 inches overall length with a 2.047-inch spiral flute, it fits standard drill chucks and CNC setups alike. This bit is suited for trade professionals and machinists who need consistent, repeatable results in demanding materials.

This drill bit is rated for primary use in titanium and other high-strength metals where standard high-speed steel bits lose their edge quickly. The right-hand spiral flute and web-thinned, tapered web geometry improve chip evacuation and reduce heat buildup during extended cuts. It is a single-piece, straight-cylindrical shank bit appropriate for hand-held drilling equipment, drill presses, and CNC machining centers in fabrication, maintenance, and industrial service environments.

Key Features

• Cobalt steel construction retains cutting hardness at high operating temperatures
• 135-degree split point reduces bit walking and lowers required entry thrust
• Web-thinned, tapered web improves chip flow and reduces heat buildup
• Gold finish provides visual identification of cobalt grade material
• Straight-cylindrical shank fits standard 3-jaw chucks and collet systems
• Meets DIN 338 and NAS 907 Type J standards for dimensional and performance compliance

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for applications requiring a 5 mm diameter cobalt bit with a straight-cylindrical shank, conforming to DIN 338 and NAS 907 Type J specifications.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and industrial trade professionals. Before mounting, confirm the drill chuck or collet is fully seated and tightened to prevent shank slippage. Use appropriate cutting fluid or coolant when drilling titanium and other hard alloys to extend bit life, noting this bit does not support internal coolant-through delivery. Inspect the cutting edges for wear before each use, as cobalt bits used beyond their service life can fracture under load.
