Eagle Cutting Tool TAC40-027-I Hss Jobber Drill 27/64

Product Description

The EAGLE CUTTING TOOL TAC40-027-I is a 27/64-inch high-speed steel (HSS) jobber-length drill bit suited for general-purpose drilling in metal, wood, and plastics. Jobber-length bits offer a balanced combination of reach and rigidity, making them a standard choice across fabrication shops, plumbing rough-in work, electrical panel installation, and HVAC equipment mounting. The HSS construction provides sufficient heat resistance for intermittent drilling in ferrous and non-ferrous materials without requiring carbide tooling. At 1.2 pounds per packaged unit, this bit ships ready for immediate use on the job site or in the shop.

This drill bit is appropriate for trade professionals who need a reliable 27/64-inch diameter hole for bolt clearance, conduit anchor points, pipe hanger hardware, or sheet metal applications. The 27/64-inch diameter is commonly used where a slightly oversized clearance hole is required for 3/8-inch fasteners. Electricians, plumbers, HVAC installers, and general contractors will find this size useful across a wide range of structural and mechanical drilling tasks in both residential and light commercial settings.

Key Features

• 27/64-inch diameter HSS construction for heat-resistant performance in metal and multi-material drilling
• Jobber-length flute geometry balances reach with lateral stiffness to reduce deflection during use
• Suitable for ferrous and non-ferrous metals, wood, and plastics
• Standard shank compatible with conventional drill chucks and magnetic drill press adapters
• Minimum order quantity of 1 unit for flexible purchasing

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with conventional three-jaw drill chucks found on portable drills, drill presses, and magnetic base drills used in trade and industrial applications.

Installation Notes

A licensed tradesperson or qualified mechanic should select the appropriate drill speed for the material being drilled — slower speeds are recommended for harder metals to prevent premature bit wear. Secure the workpiece before drilling to prevent movement and maintain bit alignment. Use cutting fluid when drilling steel to extend bit life and improve hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
