Titan Usa CD40913 Jobber Drill Bit Letter L Hss

Product Description

The TITAN USA CD40913 is a letter-size L jobber-length drill bit machined from high speed steel with a bright, uncoated finish. It carries a 118-degree standard point angle and a right-hand spiral flute configuration. The overall length is 4.375 inches with a flute length of 3.0625 inches, giving it a 10xD flute-to-diameter ratio suited for general-purpose through-hole and blind drilling operations. The straight-cylindrical shank measures 0.295 inches in diameter, matching the drill diameter, and seats cleanly in standard three-jaw chucks. This bit is sized at 0.295 inches decimal with a tolerance of -0.0010 to +0.0000 inches, making it appropriate where close-tolerance hole sizing matters.

This drill bit is designed for use in non-ferrous metals including aluminum, brass, copper, and similar materials. It suits production and maintenance drilling applications in machine shops, fabrication environments, and field service work where a standard jobber-length bit fits the task. The two-flute regular spiral geometry provides good chip evacuation in softer non-ferrous stock. It is compatible with portable drills, drill presses, and CNC drilling operations that accept straight-cylindrical shanks. No coolant-through capability is present, so external cutting fluid or dry drilling methods apply depending on material and feed rate.

Key Features

• Letter L sizing at 0.295 inches decimal diameter with -0.0010 to +0.0000 inch tolerance
• 118-degree standard point angle for general-purpose entry into non-ferrous metals
• High speed steel construction with bright, uncoated finish
• Right-hand, two-flute regular spiral for consistent chip clearance
• Straight-cylindrical shank fits standard three-jaw and keyless chucks
• Maximum drilling depth of 3.0625 inches matches full flute length

Compatibility

Designed as a standard jobber-length replacement drill bit for use in any drill press, hand drill, or CNC spindle accepting a 0.295-inch straight-cylindrical shank. Intended for primary use in non-ferrous metal workpieces per Series CD40 application guidelines.

Installation Notes

Secure the shank fully into the chuck and verify there is no runout before drilling. Ensure the workpiece is clamped or fixtured before starting the cut to prevent walking on entry. Apply cutting fluid when drilling non-ferrous metals at higher feed rates to extend tool life and improve hole finish. Inspect the cutting edges for chipping before each use and replace the bit if edge integrity is compromised.
