Titan Usa CD50303 Cobalt Jobber Drill Bit Letter J

Product Description

The TITAN USA CD50303 is a cobalt jobber-length drill bit sized to letter J (0.242 inches diameter), designed for drilling into hard and abrasion-resistant materials. It features a 135-degree split point that reduces walking and allows faster penetration without a center punch. The oxide and gold coating provides additional surface hardness and lubricity. With an overall length of 4 inches and a 2-3/4-inch flute length, this bit fits standard drill chucks and magnetic drill presses alike. It is suited for machinists, maintenance technicians, and fabricators working with tough materials in production or field environments.

This bit is intended for drilling stainless steel, superalloys, and titanium — workpiece materials categorized under ISO application codes M and S. Its cobalt steel construction maintains cutting edge integrity at elevated temperatures generated when machining these materials. The straight cylindrical shank (0.242 inches) seats directly in standard keyless or keyed chucks. It is appropriate for CNC drill presses, manual drill presses, and hand-held drilling applications where a jobber-length bit is specified. Single-bit packaging makes it a practical choice for replacement or low-volume use.

Key Features

• Cobalt construction retains hardness at high cutting temperatures for stainless steel and superalloy applications
• 135-degree split point reduces thrust force and eliminates the need for center punching
• Oxide and gold coating adds surface lubricity and corrosion resistance
• Regular spiral, 2-flute design provides efficient chip evacuation in deep holes
• Straight cylindrical shank fits standard drill chucks without adapters
• 11xD flute-to-diameter ratio delivers jobber-length reach for a wide range of drilling depths

Compatibility

Designed as a jobber-length replacement drill bit for use in standard drill chucks accepting a 0.242-inch straight shank, compatible with CNC and manual drilling equipment used on stainless steel, superalloys, and titanium workpieces.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with drill press or hand-drill operation. Ensure the machine is fully powered down and the chuck is secured before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel and superalloys to manage heat buildup and extend tool life. Inspect the cutting edges before use and discard bits showing chipping or deformation.
