Chicago-latrobe 45283 5mm Hss Jobber Drill Bit 118

Product Description

The CHICAGO-LATROBE 45283 is a 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 and features a 118-degree radial drill point with web thinning for improved penetration. The bit measures 5 mm in diameter with an overall length of 3.39 inches and a flute length of 2.05 inches. The two-flute spiral configuration with a tapered web promotes chip evacuation during drilling. This bit is suitable for use in drill presses, hand drills, and CNC setups where a standard jobber-length HSS bit is specified.

This bit is built to DIN 338 standards and falls within the Series 150D product line from CHICAGO-LATROBE. It is intended for drilling non-ferrous metals such as aluminum, brass, and copper in both production and maintenance applications. The straight-cylindrical shank accommodates standard three-jaw chucks across a wide range of drilling equipment. Typical use cases include fabrication shops, field service work, and light manufacturing environments where consistent hole quality in softer metals is required.

Key Features

• 5 mm diameter with a diameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing
• 118-degree radial drill point with web thinning for reduced thrust and cleaner entry
• Two-flute regular spiral design promotes efficient chip removal
• High speed steel construction provides durability in general-purpose drilling applications
• Bright, uncoated finish suitable for use with cutting fluids or dry
• Conforms to DIN 338 specification for jobber-length drill bits

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw chucks and collet systems accepting a 5 mm straight-cylindrical shank. Intended for drilling non-ferrous metals per the DIN 338 standard.

Installation Notes

Secure the shank fully in the chuck before drilling and verify the workpiece is clamped or fixtured to prevent rotation. Power down and de-energize any drilling equipment before changing or inspecting bits. Inspect the cutting edges for wear or chipping before each use, as a damaged point can cause oversized or off-center holes. Use appropriate cutting fluid for non-ferrous metals to extend bit life and improve surface finish.
