Chicago-latrobe 56324 Reduced Shank Drill Bit 3/8 in Hss

Product Description

The CHICAGO-LATROBE 56324 is a reduced shank twist drill bit designed for portable drilling applications across metal, wood, and sheet metal. The bit carries a 3/8 inch cutting diameter with a reduced 1/4 inch straight-cylindrical shank, allowing it to chuck into standard 1/4 inch capacity drill drivers and portable drills. Manufactured from high speed steel, it features a 118-degree standard point angle and a two-flute spiral design with a regular helix. Overall length is 3-1/8 inches with a 1-11/16 inch flute length. The coated finish provides basic abrasion resistance during general-purpose use. Weight is 0.01 pounds.

This bit is suited for general-purpose portable drilling in light fabrication, maintenance, and field service environments. Primary workpiece materials include aluminum, sheet metal, and wood. Secondary materials include mild steel, additional aluminum grades, and wood composites. The reduced shank configuration makes it particularly useful when a larger cutting diameter is needed with a smaller-capacity chuck. It is a right-hand cut bit and does not require coolant for typical applications in its intended material range.

Key Features

• 3/8 inch cutting diameter with reduced 1/4 inch shank for use in standard 1/4 inch chucks
• High speed steel construction for durability across aluminum, mild steel, sheet metal, and wood
• 118-degree standard point angle for general-purpose drilling entry
• Two-flute regular spiral design promotes chip evacuation during through-drilling
• Coated finish for added wear resistance
• Diameter tolerance held to +0.0000 to -0.0010 inches for consistent hole sizing

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with portable drills and drill drivers accepting a 1/4 inch straight-cylindrical shank. Suitable for drilling aluminum, mild steel, sheet metal, and wood as identified in Series 239 application data.

Installation Notes

Install and replace drill bits only after confirming the drill or driver is powered off and, for pneumatic tools, disconnected from the air supply. Secure the shank fully within the chuck and tighten according to the tool manufacturer's guidelines before operation. Wear appropriate eye protection when drilling metal or sheet stock. For drilling into structural steel or pressure-containing components in trade applications, verify that bit size and material rating meet applicable job specifications and applicable code requirements.
