Titan Usa CD40304 Jobber Drill Bit Letter D Hss Black Oxide

Product Description

The TITAN USA CD40304 is a Letter D jobber-length drill bit ground from high speed steel (HSS) with a black oxide coating for reduced friction and improved chip evacuation. It measures 0.2460 inches in diameter and carries a 118-degree standard point angle suited for general-purpose drilling in a wide range of materials. The overall length is 4 inches, with a 2.75-inch spiral flute length and a straight-cylindrical shank. The two-flute, right-hand spiral design is part of the Series CD40 line and is intended for use in hand drills, drill presses, and CNC drilling operations. Machinists, fabricators, and maintenance technicians are the primary installers of this bit.

The CD40304 is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. Its regular spiral geometry and 11xD flute-to-diameter ratio make it a practical general-purpose choice for production drilling and maintenance work alike. The black oxide finish provides mild corrosion resistance and reduces galling during dry cutting operations where coolant-through capability is not required. This bit is sold individually and ships as a single unit.

Key Features

• Letter D diameter at 0.2460 inches with a tolerance of -0.0007 to +0.0000 inches for consistent hole sizing
• 118-degree standard point angle for general-purpose entry in ferrous and non-ferrous workpieces
• Black oxide coating reduces surface friction and provides light corrosion resistance
• 2.75-inch maximum drilling depth matches the full flute length for chip clearance
• Straight-cylindrical shank at 0.2460 inches diameter fits standard drill chucks without adapters
• Right-hand, two-flute regular spiral design compatible with conventional drilling machines and hand tools

Compatibility

Compatible with drilling applications in steel, stainless steel, cast iron, non-ferrous metals, and superalloys and titanium (ISO material codes P, M, K, N, and S). Designed as a standard replacement or production jobber drill bit for any drill press, hand drill, or CNC machine accepting a straight-cylindrical shank at 0.2460 inches diameter.

Installation Notes

This bit is installed by machinists and maintenance technicians in machine shop and field settings. Secure the shank fully in the chuck and verify runout before drilling. For steel and stainless workpieces, use appropriate cutting fluid to extend edge life, as this bit does not support coolant-through delivery. Inspect the point for wear or chipping before each use and replace the bit when the cutting edge shows visible dulling to avoid oversized or off-location holes.
