Titan Usa CD50027 Cobalt Jobber Drill 27/64 in

Product Description

The TITAN USA CD50027 is a cobalt jobber-length drill bit designed for drilling into hard and abrasion-resistant materials. Built from cobalt steel with an oxide and TiN coating, it resists heat buildup and edge wear during high-cycle drilling operations. The 135-degree split point reduces walking on entry and lowers the thrust force needed to start the cut, making it suitable for use without a center punch on most materials. At 5.375 inches overall length with a 3.9375-inch flute, this bit delivers the reach and chip clearance needed for production and maintenance drilling tasks. It is sold individually and suited for use in standard drill presses, hand drills, and CNC drilling setups.

The CD50027 is built for drilling stainless steel, superalloys, and titanium — materials that generate high cutting temperatures and accelerate wear on standard high-speed steel tooling. The cobalt construction and heat-resistant coating make it a common choice for mechanical contractors, pipefitters, and maintenance machinists working with 300-series stainless, Inconel, and similar alloys. It is also used in general fabrication shops where a single versatile bit must handle both common steel and harder-to-machine materials in a single setup.

Key Features

• Cobalt steel construction for heat and wear resistance in tough materials
• 135-degree split point reduces entry walking and lowers required thrust
• Oxide and TiN coating extends tool life in high-friction applications
• Regular spiral flute design provides consistent chip evacuation
• Straight cylindrical shank fits standard 3-jaw chucks without modification
• 27/64 inch diameter with zero flats on shank for secure, centered clamping

Compatibility

Designed as a jobber-length replacement drill bit for use in standard drill chucks accepting a straight cylindrical shank at 27/64 inch (0.4219 inches) diameter, compatible with drill presses, hand drills, and CNC machines with appropriate chuck capacity.

Installation Notes

Installation of this bit requires a chuck rated to accept a 27/64 inch straight shank; verify chuck capacity before seating the bit. Ensure the drill press or driver is powered off and the chuck is fully tightened before beginning any drilling operation. Cobalt bits are appropriate for use without cutting fluid in many applications, but coolant or cutting oil is recommended when drilling stainless steel or superalloys to further extend tool life. Do not use this bit to drill hardened steel beyond its rated workpiece material range.
