Titan Usa CD50317 Cobalt Jobber Drill Bit Letter Q

Product Description

The TITAN USA CD50317 is a cobalt jobber-length drill bit sized to letter Q (0.3320 inches decimal) with a 135-degree split point. Designed for right-hand cutting, the bit features a regular spiral flute, straight-cylindrical shank, and an oxide and TiN coating for extended tool life. Overall length is 4.75 inches with a flute length of 3.4375 inches. The split point geometry reduces walking on entry and lowers thrust requirements, making this bit well-suited for production drilling where positioning accuracy and tool longevity matter.

This drill bit is built for cutting stainless steel, superalloys, and titanium — materials that generate high heat and work-harden under tooling pressure. Cobalt construction and the dual-coating combination allow the bit to retain hardness at elevated temperatures. It is appropriate for job shop work, maintenance shops, and field applications where a reliable letter-size drill is needed for tough ferrous and non-ferrous workpiece materials. Coolant-through is not available on this bit, so appropriate surface cutting speeds and chip clearing techniques should be applied when working with difficult alloys.

Key Features

• Letter Q size at 0.3320 inches decimal diameter for precise hole sizing
• Cobalt construction with oxide and TiN coating for heat and wear resistance
• 135-degree split point reduces entry walking and cutting thrust
• Regular right-hand spiral flute with 3.4375-inch flute length for deep chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• 2-flute design optimized for high-temperature alloys including stainless steel and titanium

Compatibility

Designed for use in standard drill chucks accepting a 0.3320-inch straight-cylindrical shank. Intended primary workpiece materials are stainless steel, superalloys, and titanium per Series CD50 design specifications.

Installation Notes

This bit is installed and removed by a machinist or metalworker using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. When drilling stainless steel or titanium, maintain consistent feed pressure to avoid work hardening and reduce heat buildup through appropriate cutting speed selection. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
