Hertel K027783AS Spiral Point Tap M16 X 2 Metric Coarse

Product Description

The HERTEL K027783AS is a spiral point tap designed for cutting metric coarse internal threads in through-hole applications. The spiral point geometry pushes chips forward ahead of the cutting zone, keeping the flutes clear and allowing continuous feed without chip packing. Built from high speed steel, this tap handles a wide range of ferrous and non-ferrous materials in both production and maintenance environments. The M16 x 2 thread size and 6H class of fit make it a standard choice for general-purpose metric fastener applications. With a D7 thread limit, it produces threads sized appropriately for plated or coated fasteners. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users.

This tap is suited for through-hole threading operations in machine shops, manufacturing facilities, and industrial maintenance settings. The plug chamfer provides a gradual lead-in, distributing cutting load across several threads and making it well-suited for both hand tapping and machine tapping in drill presses, CNC machining centers, and tapping heads. Right-hand thread direction matches standard M16 x 2 fastener specifications used in structural, mechanical, and equipment assemblies across general industry.

Key Features

• Spiral point design pushes chips forward, ideal for through-hole threading
• M16 x 2 metric coarse thread form meets standard metric fastener specifications
• 6H class of fit provides general-purpose tolerance suitable for most metric bolt applications
• D7 thread limit accommodates plated or coated mating fasteners
• High speed steel construction offers durability across a broad range of workpiece materials
• 3-flute configuration balances cutting load and chip clearance

Compatibility

Designed for use in through-hole applications requiring M16 x 2 metric coarse internal threads with a 6H class of fit. Compatible with standard tapping chucks, floating tap holders, and rigid tapping setups on manual and CNC machine tools.

Installation Notes

This tap should be installed in a suitable tap holder or chuck rated for the shank diameter before use. Always secure the workpiece firmly and ensure the spindle axis is aligned with the pre-drilled hole to avoid tap breakage. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Follow shop safety practices and machine manufacturer guidelines when setting feed rates and spindle speeds for tapping operations.
