Regal Cutting Tools 027284AS M10 Extension Pulley Tap

Product Description

The REGAL CUTTING TOOLS 027284AS is an extension pulley tap designed for threading M10 metric coarse holes in difficult-to-reach locations. Built from high-speed steel with a bright finish, this tap features a plug chamfer and four right-hand flutes for efficient chip evacuation during threading operations. The extended overall length of 6 inches allows access to recessed or deep cavities where standard-length taps cannot reach. It carries a D6 thread limit and a 6H class of fit, making it suitable for precision metric threading applications in production and maintenance environments. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this tool.

This extension pulley tap is intended for threading M10 metric coarse holes in applications where clearance or depth makes standard tap access impractical. Common scenarios include threading pulley hubs, machinery frames, and other industrial components with obstructed or deep-set bore locations. The 1.25-inch thread depth capacity handles typical fastener engagement lengths for M10 hardware. The bright finish reduces friction and helps with visual inspection of the cutting edges between uses.

Key Features

• Extended 6-inch overall length for difficult-to-reach threading applications
• M10 metric coarse thread standard with 6H class of fit and D6 thread limit
• Four right-hand flutes with plug chamfer for standard through-hole and deep threading
• High-speed steel construction for durability across a range of workpiece materials
• Bright finish reduces friction and simplifies edge inspection
• 0.381-inch shank diameter with 0.44-inch square length for secure chuck or tap holder engagement

Compatibility

Designed as an OEM-style replacement or direct-use extension tap for M10 metric coarse threading applications in industrial machining, maintenance, and repair operations.

Installation Notes

This tap should be used with a properly sized tap wrench or extension tap holder rated for the shank diameter. Ensure the workpiece is securely fixtured before beginning threading to prevent tap breakage. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve a clean thread form. Follow applicable shop safety procedures and wear eye protection when operating tapping equipment.
