Titan Usa CD50020 Cobalt Jobber Drill Bit 5/16 in

Product Description

The TITAN USA CD50020 is a cobalt jobber-length drill bit designed for demanding drilling applications in hard and abrasive materials. Built from cobalt high-speed steel with an oxide and TiN coating, this bit delivers extended tool life and heat resistance compared to standard HSS drills. It features a 135-degree split point that reduces walking and requires no center punch on most workpieces. The straight-cylindrical shank measures 5/16 inches in diameter, and the overall length is 4.5 inches. This bit is a go-to tool for machinists, pipefitters, and field technicians who regularly work with tough base metals.

The CD50020 is rated for drilling stainless steel, superalloys, and titanium — materials that generate significant heat and wear conventional drill bits quickly. The cobalt construction handles the elevated temperatures produced when cutting these alloys. With a 3.1875-inch flute length and a 10xD flute-to-diameter ratio, it provides adequate chip clearance for through-holes in plate and structural stock. Typical applications include fabrication shops, mechanical contractors drilling stainless pipe flanges, and service technicians drilling hardened mounting surfaces. This is a right-hand, spiral-flute bit in the Series CD50 product line.

Key Features

• Cobalt high-speed steel construction for heat resistance in hard-material drilling
• Oxide and TiN dual coating extends cutting edge life and reduces friction
• 135-degree split point reduces thrust force and eliminates walking on entry
• Right-hand spiral flute efficiently evacuates chips during through-hole drilling
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters
• No coolant-through design — suitable for hand drilling and standard drill press use

Compatibility

Designed for use in standard drill presses, magnetic-base drills, and hand drills equipped with a 3-jaw chuck accepting a 5/16-inch straight shank. Rated for primary workpiece materials including stainless steel, superalloys, and titanium (material codes M and S).

Installation Notes

Install and remove this bit only when the drill is fully powered down and the chuck key is clear of the chuck. Secure the workpiece firmly before drilling to prevent spinning, which is a common hazard when breaking through hard alloys. Follow applicable OSHA machine-guarding requirements and shop safety protocols when operating drill presses. Use cutting fluid or lubricant appropriate for stainless steel and superalloys to extend bit life and improve cut quality.
