Chicago-latrobe 44310 Jobber Drill Bit Wire 40 Hss

Product Description

The CHICAGO-LATROBE 44310 is a jobber-length drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. Manufactured from high-speed steel with a bright uncoated finish, this bit measures 0.0980 inches in diameter (Wire Size 40) and features a 118-degree standard point angle. The overall length is 2-3/8 inches with a 1-3/8-inch flute length and a straight-cylindrical shank. A tapered web with web-thinning geometry reduces thrust at the tip and improves chip evacuation. Machinists, maintenance technicians, and metalworking tradespeople are the primary users of this bit.

This bit is suited for light-duty drilling operations in non-ferrous metals, plastics, and similar workpiece materials where a general-purpose HSS bit is appropriate. The regular spiral flute and right-hand cut make it compatible with standard drill presses, hand drills, and CNC setups running clockwise spindle rotation. The 0.0980-inch diameter corresponds to standard Wire Size 40, making it a direct fit for applications requiring that specific bore dimension. Part of the Series 150D line, it conforms to DIN 338 standards.

Key Features

• Wire Size 40 diameter (0.0980 inches) for precise bore sizing in non-ferrous and general-purpose applications
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction with bright uncoated finish for general-purpose use
• Regular spiral, right-hand cut flute for compatibility with standard clockwise-rotation equipment
• Straight-cylindrical shank (0.0980 inches diameter) fits standard drill chucks without modification
• Meets DIN 338 standards for jobber-length drill geometry and dimensional tolerances

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accommodating straight-cylindrical shanks at 0.0980 inches diameter; suitable for drill presses, hand drills, and compatible CNC spindles running right-hand (clockwise) rotation.

Installation Notes

Secure the shank fully in the drill chuck and verify concentricity before operation. Always wear appropriate eye protection and secure the workpiece before drilling. For best results in non-ferrous materials, use appropriate cutting fluid and keep spindle speed within the recommended range for the material and bit diameter. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
