Chicago-latrobe 11036 Aircraft Extension Drill Bit Hss

Product Description

The CHICAGO-LATROBE 11036 is a Series 906 aircraft extension drill bit designed for deep-reach drilling in metal and structural materials. Built from high speed steel with an oxide finish, it features a 135-degree split point that is self-centering and web-thinned for reduced thrust and cleaner entry. The straight-cylindrical shank measures 0.204 inches in diameter, and the two-flute spiral design runs a 2.5-inch flute length within a 6-inch overall body. This bit is suited for production and MRO applications where standard-length tooling cannot reach, and is typically installed by machinists, aircraft maintenance technicians, and general metalworking trades.

The 11036 fits applications requiring extended reach in tight or deep bores across aerospace, sheet metal, and general fabrication environments. The wire gauge No. 6 sizing (0.204 inches decimal) makes it compatible with close-tolerance hole applications. The right-hand cutting direction and tapered web configuration support consistent chip evacuation in both hand-drill and drill-press setups. It meets NAS 907 Type B standards, making it appropriate for aerospace MRO and structural repair work where dimensional and material compliance is required.

Key Features

• 135-degree split point with web thinning reduces walking and lowers drilling thrust
• Self-centering tip eliminates the need for a center punch in most setups
• 6-inch overall length provides extended reach over standard jobber-length bits
• High speed steel construction with oxide finish for general-purpose metal drilling
• Straight-cylindrical shank (0.204 inches) fits standard drill chucks without adapters
• Meets NAS 907 Type B standard for aerospace and structural applications

Compatibility

Designed as a general-purpose extended-reach drill bit for use in standard drill chucks accepting a 0.204-inch straight shank, suitable for aerospace MRO, sheet metal fabrication, and structural metalworking applications meeting NAS 907 Type B requirements.

Installation Notes

This bit is installed by machinists and maintenance technicians using a standard keyed or keyless drill chuck. Secure the shank fully into the chuck before operation and verify runout before drilling production holes. Use appropriate cutting fluid for ferrous materials to extend tool life and improve hole finish. Follow shop safety protocols and applicable OSHA machine-guarding requirements when operating drill presses or hand drills.
