Chicago-latrobe 48524 Screw Machine Drill Bit 0.375 in

Product Description

The CHICAGO-LATROBE 48524 is a screw machine length drill bit designed for high-throughput metal drilling in industrial and trade applications. Built from high speed steel (HSS) with a bright/uncoated finish, it measures 0.375 inches in diameter with a 118-degree standard point angle and a 3-1/8-inch overall length. The two-flute spiral design with a web-thinned, parallel web configuration promotes efficient chip evacuation and reduced entry force. This bit is suited for machinists, maintenance technicians, and trade professionals working in production environments where a compact, stubby drill profile is needed for rigidity and accuracy.

This screw machine length drill bit is intended for use on cast iron, non-ferrous metals, and steel in general purpose drilling operations. Its straight cylindrical shank accepts standard drill chucks on drill presses, CNC machines, hand drills, and screw machine setups. The shorter flute and overall length compared to jobber-length bits provides added rigidity, making it a preferred choice in high-speed production or repetitive-drilling scenarios where deflection must be minimized.

Key Features

• 0.375-inch diameter with a tight tolerance of +0.0000 to -0.0010 inches for precision fitment
• 118-degree standard point angle for general purpose entry on ferrous and non-ferrous workpieces
• High speed steel construction provides durability across a wide range of metal substrates
• Web-thinned parallel web reduces thrust load and improves chip clearance
• Screw machine length profile (3-1/8 inches overall) delivers superior rigidity over jobber-length bits
• Right-hand spiral flute, bright/uncoated finish — compatible with standard cutting fluids

Compatibility

Designed as a general purpose screw machine length drill bit compatible with drill presses, CNC drilling machines, and hand-held drill equipment using standard straight-cylindrical shank chucks. Primary workpiece materials include cast iron, non-ferrous metal, and steel. Conforms to ISO standards per Series 157 specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tools and applicable machine guarding requirements. Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is observed.
