Titan Usa CD47616 Jobber Drill Bit Letter R Hss Tin

Product Description

The TITAN USA CD47616 is a letter-size R jobber-length drill bit designed for general-purpose drilling in metal and non-ferrous materials. Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended wear resistance and reduced friction during cutting. The bit measures 0.3230 inches in diameter and 4.625 inches overall, with a 118-degree standard point angle suited for a wide range of common drilling applications. A regular spiral flute design promotes efficient chip evacuation. Licensed trades and machinists working in fabrication, mechanical, and HVAC sheet-metal environments will find this bit a reliable daily-use option.

This jobber drill is intended for drilling into non-ferrous metals and similar workpiece materials. The straight cylindrical shank seats securely in standard drill chucks without requiring a morse taper adapter or reduction sleeve. With a flute length of 3.3125 inches and a maximum drilling depth matching that dimension, the CD47616 handles moderate-depth through-holes and blind holes in production and field settings alike. It ships individually and is sold as a single unit.

Key Features

• Letter R size: 0.3230 inch diameter with a tolerance of -0.0010 to +0.0000 inches
• 118-degree standard point angle for consistent entry on flat and curved surfaces
• TiN coating over high speed steel substrate for improved surface hardness and tool life
• Regular spiral flute with 2 flutes for effective chip clearing
• Straight cylindrical shank fits standard drill chucks without adapters
• 10xD flute-to-diameter ratio for jobber-length reach

Compatibility

Designed as a standard jobber-length drill bit suitable for use in benchtop drill presses, hand drills, and CNC drilling setups that accept a straight cylindrical shank of 0.3230 inches.

Installation Notes

Secure the shank fully into the drill chuck and tighten per the chuck manufacturer's recommendation before operation. Always wear appropriate eye protection and secure the workpiece before drilling. When drilling non-ferrous metals, use a cutting fluid to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the TiN coating is heavily worn at the tip.
