Chicago-latrobe 42695 Jobber Drill Bit Wire 25 Tialn Hss

Product Description

The CHICAGO-LATROBE 42695 is a jobber-length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from high speed steel (HSS) with a TiAlN coating, this bit handles tough materials including titanium. It carries a wire gauge size of 25, which corresponds to a decimal diameter of 0.1495 inches, and features a 135-degree split point for fast, self-centering penetration with reduced walking. The overall length is 3 inches, with a 1.875-inch flute length. The right-hand spiral flute geometry and web-thinned, tapered web construction promote efficient chip evacuation and reduced thrust during cutting. This bit meets NAS 907 Type B standards, making it appropriate for aerospace-grade work and precision fabrication.

This drill bit is suited for use in metal fabrication shops, maintenance and repair operations, aerospace service environments, and precision manufacturing settings. The TiAlN coating extends tool life when drilling hard or abrasive workpiece materials, with titanium listed as the primary workpiece material. The straight-cylindrical shank seats securely in standard drill chucks and collets. The Series 150ASP-TA designation indicates a heavy-duty grade intended for production drilling where consistent tolerances are critical. This bit ships individually and is appropriate for both bench drill press use and hand drill applications where setup rigidity is maintained.

Key Features

• TiAlN coating extends tool life on titanium and other hard workpiece materials
• 135-degree split point enables self-centering entry and reduces axial thrust
• Web-thinned, tapered web construction improves chip flow and lowers cutting resistance
• Right-hand regular spiral flute promotes consistent chip evacuation
• Meets NAS 907 Type B specification for aerospace and precision applications
• Straight-cylindrical shank fits standard drill chucks and collets without adapters

Compatibility

Designed as a direct-fit jobber-length drill bit for use in standard drill chucks and collets accepting a straight-cylindrical shank at the 0.1495-inch diameter range. Compatible with applications requiring NAS 907 Type B drill bit compliance.

Installation Notes

Secure the straight-cylindrical shank fully in a drill chuck or collet before operation. Machinist or toolroom technicians should verify spindle runout is within tolerance before use on precision work to protect the listed diameter tolerance range of -0.0007 to 0.0000 inches. Use appropriate cutting fluid or coolant where workpiece material and setup allow, noting this bit does not support coolant-through delivery. Follow applicable shop safety protocols including eye protection and workpiece fixturing before drilling.
