Hertel K025320AS Spiral Point Tap M11x1.50 Metric Coarse

Product Description

The HERTEL K025320AS is a spiral point tap designed for cutting M11x1.50 metric coarse internal threads in through-hole applications. Manufactured from high-speed steel with a bright uncoated finish, this plug-chamfer tap drives chips forward ahead of the cutting zone, making it well suited for production threading on CNC machining centers, drill presses, and tapping machines. The three-flute geometry provides a balance of chip clearance and tool rigidity. With a thread length of 1.4375 inches and a D5 thread limit, the tap delivers consistent fit for standard metric fastener applications.

This tap is intended for threading through-holes in ferrous and non-ferrous materials where a plug chamfer start and forward chip ejection are appropriate. The right-hand cut and metric coarse pitch make it a direct-fit solution for general-purpose industrial machining, maintenance, and repair work in manufacturing, fabrication, and machine shop environments. It is typically installed by machinists, toolmakers, and maintenance technicians.

Key Features

• Spiral point geometry pushes chips forward, reducing clogging in through-hole threading operations
• High-speed steel construction provides durability across a range of workpiece materials
• Plug chamfer (3-5 thread lead) allows easy thread starting in through-hole applications
• D5 thread limit provides controlled oversize tolerance for standard metric fits
• Bright uncoated finish suitable for use with cutting fluids across general-purpose applications
• Right-hand thread direction matches standard M11x1.50 metric coarse fastener specifications

Compatibility

Designed as an OEM-style threading tool for M11x1.50 metric coarse through-hole applications in general-purpose machining and maintenance operations.

Installation Notes

This tap is installed by machinists and toolroom technicians using a tapping machine, CNC machining center, or hand tap wrench. Always ensure the workpiece is securely fixtured and that the tap is properly aligned with the pilot hole before engagement. Use an appropriate cutting fluid or tapping oil to extend tool life and improve thread quality. Inspect the tap for wear or chipping regularly and replace before thread quality degrades.
