Chicago-latrobe 46144 Jobber Length Drill Bit Wire 74

Product Description

The CHICAGO-LATROBE 46144 is a jobber length drill bit sized to wire gauge 74, equivalent to 0.0225 inches in decimal diameter. Built from high speed steel with a bright uncoated finish, this bit is designed for general-purpose drilling in steel and similar materials. The 118-degree standard point angle and web-thinned, tapered web configuration promote clean entry and reduced thrust at the cutting edge. A fast spiral flute geometry aids chip evacuation during through-hole drilling. Licensed professionals and machinists working with small-diameter hole requirements will find this bit suited to precision drilling tasks in production and maintenance environments.

The 46144 fits applications where tight-tolerance, small-diameter holes are required in ferrous metals and general-purpose workpiece materials. With an overall length of 1 inch and a flute length of 0.25 inches, this bit is appropriate for use in standard drill chucks, CNC equipment, and benchtop drill presses. Its straight-cylindrical shank at 0.0225 inches diameter and 0.75 inches shank length ensures secure seating in collet-style and keyed chuck setups. Typical use cases include light fabrication, sheet metal work, and maintenance repair operations requiring wire-gauge sizing.

Compatibility

Designed as a general-purpose replacement or stock bit for applications requiring wire gauge 74 jobber length drill bits with a straight-cylindrical shank.

Installation Notes

Installation and use of small-diameter drill bits should be performed by machinists or trade professionals familiar with proper chuck seating and spindle speed selection. Secure the shank fully in the chuck or collet before operation to prevent runout or bit breakage. At this diameter, spindle speeds should be appropriate for the workpiece material and machine type — consult published speeds and feeds charts for HSS bits in steel. Never apply side-load pressure to a bit of this diameter; feed force should be light and consistent.
