Chicago-latrobe 44295 Jobber Drill Bit No 25 Hss

Product Description

The CHICAGO-LATROBE 44295 is a jobber-length drill bit sized to wire gauge No. 25, with a decimal diameter of 0.1495 inches. Built from high-speed steel with a bright, uncoated finish, it is designed for general-purpose drilling in non-ferrous metals and similar materials. The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry force and help center the bit on the workpiece. At 3 inches overall length with a 1.875-inch spiral flute, this bit fits standard drill chucks and is well suited for production environments, maintenance shops, and field service work.

This bit is used in applications requiring precise small-diameter holes in non-ferrous metals such as aluminum, brass, and copper. The right-hand spiral flute with regular spiral type clears chips efficiently during through-hole and blind-hole operations. The straight-cylindrical shank diameter of 0.1495 inches seats directly in keyless or keyed chucks without an adapter. It is appropriate for use in drill presses, hand drills, and CNC drilling operations where wire-gauge sizing is specified. The Series 150D designation indicates conformance to DIN 338 standards for jobber-length geometry.

Key Features

• Wire gauge No. 25 sizing at 0.1495 inches decimal diameter for precise small-hole work
• High-speed steel construction provides durability across general-purpose drilling tasks
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and accurate starting
• Bright, uncoated finish suitable for standard cutting speeds in non-ferrous materials
• Right-hand, regular-spiral flute at 1.875 inches for efficient chip evacuation
• Conforms to DIN 338 jobber-length standard for consistent interchangeability

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to DIN 338 standards, compatible with any standard keyed or keyless drill chuck accepting a straight-cylindrical shank at 0.1495 inches diameter.

Installation Notes

Install in a properly sized chuck and tighten securely before operation. Ensure the drill press or hand tool is powered off and the workpiece is clamped before inserting or removing the bit. Use appropriate cutting fluid or lubrication when drilling non-ferrous metals to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace if the point geometry is compromised.
