Hertel G837637 Extension Tap M10 X 1.5 Spiral Point Hss

Product Description

The HERTEL G837637 is a spiral point plug extension tap designed for threading M10 x 1.5 metric coarse holes in production and maintenance machining environments. Built from high speed steel, it delivers reliable performance across a range of ferrous and non-ferrous materials. With 3 flutes, a D6 thread limit, and a 6H class of fit, this tap maintains precise tolerance control suited for standard metric fastener applications. The reduced shank design allows reach into deeper setups. Overall length is 6 inches. Right-hand flute direction is standard for conventional tapping operations. Machinists and tool crib personnel in manufacturing, fabrication, and industrial maintenance are the typical users.

This extension tap is suited for through-hole tapping operations where chip evacuation is a priority. The spiral point geometry pushes chips ahead of the cutting edge rather than packing them into the flute, making it well-suited for use in CNC machining centers, drill presses, and tapping machines on production runs. The plug chamfer provides a gradual thread lead-in, appropriate for through holes where full thread engagement is required near the entry point. It is used in general industrial machining, MRO applications, and toolroom setups requiring metric coarse threading at the M10 size.

Key Features

• Spiral point geometry pushes chips forward for efficient through-hole tapping
• M10 x 1.5 metric coarse thread size with 6H class of fit for standard tolerance applications
• D6 thread limit for controlled pitch diameter range
• High speed steel construction for broad material compatibility
• Plug chamfer for gradual thread entry in through-hole applications
• Reduced shank allows access in extended-reach setups
• Right-hand cut, 3-flute configuration for balanced cutting action

Compatibility

Designed as a standard extension tap for through-hole metric coarse tapping operations requiring an M10 x 1.5 thread with a 6H class of fit. No specific machine or system compatibility was provided in the product data.

Installation Notes

Installation is performed by machinists and toolroom technicians using a tapping machine, CNC machining center, or drill press with a tap holder or floating tap chuck. Ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled hole before engaging the cut. Use an appropriate cutting fluid for the workpiece material to extend tap life and maintain thread quality. Inspect the tap for wear or chipping before each use and replace when cutting torque increases noticeably or thread quality degrades.
