Chicago-latrobe 50345 Taper Length Drill Bit 0.052 in Hss

Product Description

The CHICAGO-LATROBE 50345 is a taper length, high speed steel twist drill bit designed for precision drilling in metal and ferrous materials. It carries a wire gauge size of 55, corresponding to a decimal diameter of 0.0520 inches, and features a standard 118-degree split point with web thinning for accurate positioning and reduced walking on entry. The straight shank and spiral flute design allow efficient chip evacuation during through-hole and blind-hole operations. At 3 inches overall length with a 1-3/4-inch flute, this bit suits applications where a standard jobber length would be too short for reach but a full extra-length bit is unnecessary.

This drill bit is suited for general-purpose use in alloy steel, carbon steel, and cast iron workpieces. The taper length format makes it a common choice for tool and die work, maintenance shops, and production environments where a moderate increase in reach over a jobber-length bit is required. Right-hand cut with a regular spiral type, it is compatible with standard drill presses, hand drills, and CNC spindles accepting straight-shank tooling. It is sold individually and requires a minimum order quantity of 12 units.

Key Features

• Wire size 55 with 0.0520-inch decimal diameter and tight tolerance of +0.0000 to -0.0005 inches
• 118-degree standard point with web thinning for reduced thrust and improved centering
• High speed steel construction for general-purpose metal drilling
• Taper length body at 3 inches OAL with 1-3/4-inch flute length for extended reach
• Right-hand cut, spiral flute, straight shank for broad machine compatibility
• Coated finish to aid in heat resistance and chip flow

Compatibility

Designed as a general-purpose replacement or production bit for use in alloy steel, carbon steel, and cast iron drilling applications where a wire-gauge taper length drill is specified.

Installation Notes

Installation is performed by machinists, tool and die makers, and maintenance technicians using standard drill chucks or collets sized for straight-shank tooling. Secure the shank fully in the chuck and verify runout before operation. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance. Power down and de-energize the machine before changing tooling.
