Chicago-latrobe 44316 Jobber Drill Bit Wire 46 Hss

Product Description

The CHICAGO-LATROBE 44316 is a wire gauge size 46 jobber length drill bit designed for precise small-hole drilling in general purpose and light industrial applications. Manufactured from high speed steel (HSS) with a bright uncoated finish, this bit measures 0.0810 inches in diameter and carries an overall length of 2.125 inches. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve centering on the workpiece. With 2 spiral flutes in a regular helix pattern, the bit efficiently clears chips during through-hole operations. Licensed machinists, HVAC technicians, electricians, and plumbers reach for bits in this size range when drilling pilot holes, sheet metal knockouts, or small-bore passages in light-gauge materials.

This drill bit is suited for non-ferrous metals and similarly machinable materials in bench-top and handheld drill applications. The straight-cylindrical shank with a 1.0-inch shank length seats securely in standard 3-jaw chucks across benchtop drill presses, handheld power drills, and drill-driver tools. The Series 150D designation places this bit within a general purpose jobber length line built to DIN 338 dimensional standards, making it a straightforward metric-compatible option for shops running both inch and metric tooling inventories.

Key Features

• Wire gauge size 46, 0.0810-inch decimal diameter with a tight tolerance of -0.0005 to 0.0000 inches
• High speed steel construction for durability across general purpose drilling tasks
• 118-degree standard point angle with web-thinned tapered web for reduced thrust and improved self-centering
• Bright uncoated finish — compatible with cutting fluids and standard HSS re-sharpening procedures
• Regular spiral flute geometry promotes clean chip evacuation in non-ferrous metals
• Meets DIN 338 dimensional standards for consistent interchangeability

Compatibility

Designed for use in standard straight-shank 3-jaw chucks; fits drill presses, handheld power drills, and drill-driver tools accepting straight-cylindrical shanks at 0.0810 inches. Primary workpiece material is non-ferrous metal per manufacturer specification. Conforms to DIN 338 jobber length standards.

Installation Notes

Install this bit into a properly tightened 3-jaw chuck before energizing the drill. Secure the workpiece with an appropriate clamp or vise — never hand-hold small workpieces during drilling. Use a cutting fluid or lubricant when drilling non-ferrous metals to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or dulling is evident to maintain dimensional accuracy.
