Hertel K020363AS Spiral Point Tap M16 X 1.5 Metric Fine

Product Description

The HERTEL K020363AS is a spiral point tap designed for threading M16 x 1.5 metric fine holes in through-hole applications. It features a plug chamfer style, 3 flutes, and a right-hand thread direction. Manufactured from high speed steel with a bright finish, this tap pushes chips ahead of the cutting edge, making it well suited for production threading in materials where chip evacuation is a priority. The shank diameter measures 0.480 inches, and the thread length is 1.813 inches. Machinists and tool room professionals use this tap in CNC machining centers, drill presses, and hand-tapping operations where a clean metric fine thread is required.

This spiral point tap is intended for use in through-hole threading operations on ferrous and non-ferrous metals requiring an M16 x 1.5 metric fine thread form. The plug chamfer allows the tap to start easily in a pre-drilled hole and is the standard choice for general-purpose production tapping. It is appropriate for machine tapping setups where coolant-through is not required, and it handles typical shop materials such as steel, aluminum, and cast iron when paired with appropriate cutting fluid and tapping speeds.

Key Features

• M16 x 1.5 metric fine thread size for precision fastening applications
• Spiral point geometry pushes chips forward, reducing clogging in through-hole applications
• 3 flutes provide a balance of chip clearance and cutting edge support
• Plug chamfer for easy starting and general-purpose machine tapping
• High speed steel construction offers good wear resistance across common shop materials
• Bright finish with no oversize designation, maintaining standard D3 thread limit

Compatibility

Designed as a standard OEM-style replacement or new-installation spiral point tap for any setup requiring an M16 x 1.5 metric fine, plug chamfer, right-hand thread tap with a D3 thread limit.

Installation Notes

This tap is installed by qualified machinists or tool and die professionals using a tapping chuck, floating tap holder, or rigid tapping setup on a machine tool or drill press. Before use, verify the pre-drilled hole diameter matches the recommended tap drill size for M16 x 1.5 metric fine thread. Apply appropriate cutting fluid or tapping compound to extend tool life and improve thread quality. Do not exceed the recommended tapping speed for the workpiece material, and avoid reversing direction abruptly, which can chip cutting edges.
