3/8" STUBBY COBALT THREADE - Brown Aviation Tool

The Brown Aviation Tool BAT31375 3/8" Stubby Cobalt Threaded Drill Bit is engineered for precision drilling in highly restricted and confined spaces. This professional-grade drill bit combines a compact design with robust material construction, making it an essential tool for automotive, industrial, and aerospace technicians tackling challenging access points. Designed for durability and consistent performance, it ensures efficient material removal even in demanding applications.

Key Features

• Compact Design for Confined Spaces: With an overall length of just 3/8", this drill bit is specifically designed to access and drill in areas where standard-length bits cannot fit.
• Premium Cobalt Construction: Manufactured from M42 8% cobalt steel, the drill bit offers superior heat resistance and extended tool life when drilling through hard and tough materials.
• Precision Threaded Shank: Features an industry-standard 1/4-28 threaded shank, allowing it to screw securely into a threaded adapter for specialized drilling applications.
• Self-Centering 135° Split Point: The 135° heavy-duty split point penetrates on contact, preventing the bit from "walking" and ensuring accurate hole placement without the need for a pilot hole.
• NAS 965 Type "D" Specifications: Built to NAS 965 Type "D" specifications, this drill bit meets stringent industry standards for quality and performance.

Applications

This 3/8" stubby cobalt threaded drill bit is ideal for professional mechanics and technicians requiring precise drilling in limited-access environments. It excels when used with threaded adapters for angle and offset drilling, particularly in automotive engine bays, industrial machinery, and aircraft assembly where space is at a premium. Its cobalt composition makes it highly effective for drilling into high tensile strength materials, including stainless steel, titanium, manganese steel, armor plate, and Inconel.
