Hertel K020347AS25 Spiral Point Tap M16 X 2 Metric Coarse

Product Description

The HERTEL K020347AS25 is a spiral point tap designed for cutting metric coarse internal threads in through-hole applications. Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The plug chamfer style allows the tap to progressively engage the workpiece, making it well suited for through-holes where chips can be pushed forward and cleared efficiently. With a 3-flute design and a D4 thread limit, this tap produces M16 x 2 threads with consistent accuracy in a range of ferrous and non-ferrous materials.

This tap is used in metalworking and machining environments where metric coarse threaded fastener holes are required. It handles through-hole tapping in materials such as steel, cast iron, aluminum, and similar machinable metals. Typical install scenarios include production machining, maintenance and repair operations, and job shop work where M16 x 2 metric coarse threads must be cut by hand or under power. The right-hand thread direction and plug chamfer make it a standard choice for general-purpose tapping on vertical mills, drill presses, or hand-tapping setups.

Key Features

• M16 x 2 metric coarse thread form for standard fastener compatibility
• High speed steel construction provides toughness and wear resistance
• TiN coating reduces friction and extends tool life between sharpenings
• 3-flute plug chamfer design pushes chips forward, suited for through-holes
• D4 thread limit for controlled fit tolerance in standard metric applications
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed as an OEM-style replacement or direct substitute spiral point tap for M16 x 2 metric coarse through-hole tapping operations in general machining applications.

Installation Notes

This tap is installed by machinists or tooling technicians using a tap wrench, tapping head, or CNC rigid tapping cycle. Always ensure the workpiece is secured and the tap is properly aligned to the pre-drilled pilot hole before engagement. Use appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Discard or resharpen the tap if cutting torque increases noticeably or thread quality degrades.
