Titan Usa CD40903 Jobber Drill Bit Letter B Hss

Product Description

The TITAN USA CD40903 is a Letter B jobber-length drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. It is manufactured from high speed steel with a bright uncoated finish, giving it solid wear resistance for everyday shop and field use. The 118-degree standard point angle is the most versatile geometry for drilling into aluminum, brass, copper, and soft alloys. At 4 inches overall length with a 2.75-inch spiral flute, the CD40903 follows the standard jobber-length format that fits most drill chucks and drill presses used by trades professionals. The straight cylindrical shank at 0.242 inches diameter seats securely in standard chucks without slipping.

This drill bit is suited for use on drill presses, hand drills, and benchtop equipment in HVAC, plumbing, and electrical trade applications where pilots, access, and clearance holes are routinely drilled through sheet metal, non-ferrous tubing, and soft-metal enclosures. The right-hand spiral flute design clears chips efficiently during through-hole drilling. The CD40903 is sold individually and is a direct fit for job-site kits or bench stock replenishment in a professional shop environment.
