Chicago-latrobe 46115 Jobber Drill Bit Wire 45 Hss

Product Description

The CHICAGO-LATROBE 46115 is a jobber length drill bit designed for general-purpose drilling in steel and similar ferrous materials. It carries a wire gauge size of 45, which corresponds to a decimal diameter of 0.0820 inches. The bit is machined from high speed steel with a bright, uncoated finish and features a 118-degree standard point angle with web thinning for reduced thrust at entry. Overall length is 2.125 inches, with a 1.125-inch flute length. The straight-cylindrical shank measures 0.0820 inches in diameter, allowing it to seat securely in standard drill chucks. This is a Series 150B bit intended for installation by machinists, maintenance technicians, and trade professionals working with light-gauge ferrous stock.

The 46115 is suited to drilling operations in steel workpieces where a small-diameter, precise hole is required. Typical applications include pilot holes, tap lead holes for small fasteners, and detail work in sheet metal or light structural stock. The fast spiral flute geometry promotes efficient chip evacuation in through-hole and blind-hole drilling. This bit is sold individually but is subject to a minimum order quantity of 12 units, making it appropriate for shop stock replenishment and toolroom inventory.

Key Features

• Wire size 45 with 0.0820-inch decimal diameter for precision small-hole work
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction rated for general-purpose steel drilling
• Fast spiral, 2-flute configuration promotes chip clearance in ferrous materials
• Bright uncoated finish; diameter tolerance held to -0.0005 to 0.0000 inches
• Straight-cylindrical shank, 1.0-inch shank length, compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill presses, hand drills, and machining center chucks accepting a 0.0820-inch straight-cylindrical shank. Primary workpiece material is steel; suitable for other ferrous materials within the general-purpose drill bit grade range.

Installation Notes

This bit is installed and operated by machinists, tool and die technicians, and maintenance trade professionals. Secure the shank fully in a properly sized drill chuck before operation and verify chuck key is removed before powering the drill. Use appropriate cutting fluid or coolant when drilling steel at sustained feed rates to preserve cutting-edge life. Inspect the point and cutting edges for wear or chipping before each use; a damaged point on a small-diameter bit can cause walk, breakage, or off-size holes.
