Chicago-latrobe 44325 Jobber Drill Bit Wire Size 55 Hss

Product Description

The CHICAGO-LATROBE 44325 is a jobber length drill bit sized to wire gauge 55 (0.0520 inches decimal), manufactured from high speed steel with a bright uncoated finish. Designed for general purpose drilling, it features a 118-degree standard point angle, a two-flute spiral configuration, and a web-thinned, tapered web for improved chisel edge performance. The straight-cylindrical shank measures 0.0520 inches in diameter, matching the cutting diameter for direct chuck engagement. At 1.875 inches overall length with a 0.875-inch flute length, this bit is suited for precision work in tight spaces or thin-stock drilling applications. It conforms to DIN 338 dimensional standards.

The 44325 is intended for use on non-ferrous metals including aluminum, brass, copper, and similar materials. Its general purpose grade and regular spiral geometry make it a reliable choice for production drilling, maintenance shops, and field service work where consistent small-diameter hole quality is required. The bit ships individually and is sold in minimum order quantities of 12 units, making it practical for stocking in service vans or shop drill-bit assortments.

Key Features

• Wire gauge size 55 with 0.0520-inch decimal diameter for precise small-hole drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner starts
• High speed steel construction provides durability across repeated use in non-ferrous materials
• Bright uncoated finish allows easy visual inspection for wear or damage
• Right-hand cut, regular spiral, two-flute design promotes efficient chip evacuation
• Conforms to DIN 338 standards for consistent dimensional tolerances

Compatibility

Designed as a general purpose jobber length drill bit for use in standard keyed or keyless drill chucks accepting straight-cylindrical shanks at 0.0520 inches diameter. Primary workpiece material is non-ferrous metal.

Installation Notes

This bit is installed by machinists, maintenance technicians, and trade professionals using bench drills, hand drills, or CNC drilling equipment. Secure the straight shank firmly in the chuck before operation and verify runout before drilling into finished workpieces. Diameter tolerance is -0.0005 to 0.0000 inches; select the appropriate bit size for close-tolerance hole requirements. Coolant-through is not supported on this bit; use surface-applied cutting fluid when drilling non-ferrous materials at higher speeds to extend tool life.
