Titan Usa CD40858 Jobber Drill Bit No. 57 Hss

Product Description

The TITAN USA CD40858 is a wire gauge jobber-length drill bit sized to No. 57 (0.0420 inches decimal equivalent) for precision small-diameter drilling in metalworking and light fabrication applications. Built from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a two-flute regular spiral configuration. The straight cylindrical shank measures 0.0420 inches in diameter, making it compatible with standard drill chucks. With an overall length of 1.625 inches and a flute length of 0.6875 inches, this bit is suited for controlled, shallow-depth drilling where tight tolerances are required. It carries a diameter tolerance of -0.0005 to +0.0000 inches.

The CD40858 is designed for drilling non-ferrous metals including aluminum, brass, copper, and similar materials. Its compact jobber length makes it practical for bench drill press work, hand drilling operations, and CNC applications where a short, rigid bit is needed for fine-hole work. This bit sees regular use by machinists, maintenance technicians, HVAC technicians drilling sheet metal, and electricians working with small conduit fittings or enclosure knockouts. It is sold individually and is part of the CD40 Series.

Key Features

• Wire gauge No. 57 size with 0.0420-inch decimal diameter for precision small-hole drilling
• 118-degree standard point angle for general-purpose entry into non-ferrous materials
• High speed steel construction provides durability across repeated use
• Bright uncoated finish allows visual wear inspection during service life
• Two-flute regular spiral design promotes chip evacuation in shallow drilling applications
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a standard wire gauge jobber drill bit for use in conventional drill chucks accepting straight cylindrical shanks. Suited for non-ferrous metal workpieces per the CD40 Series application rating.

Installation Notes

This bit is installed by a machinist, maintenance technician, or trade professional using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and confirm the chuck is tightened evenly. Always wear eye protection when drilling. For best results in non-ferrous materials, use a center punch to establish a pilot dimple before drilling to prevent bit walking.
