Walter-prototyp 5079027 Spiral Point Tap Pg7x20.00

Product Description

The WALTER-PROTOTYP 5079027 is a spiral point tap designed for cutting PG7x20.00 conduit threads in through-hole applications. Built from cobalt high-speed steel with a bright finish, this plug-style tap drives chips forward ahead of the cutting edge, keeping the flute clear during production threading. It features 4 flutes, a 20 mm thread length, and a 70 mm overall length (OAL). Right-hand cut geometry suits standard CW rotation on CNC machining centers, drill presses, and tapping arms. The cobalt base material provides added heat resistance for harder steels and tough alloys compared to standard M2 HSS taps.

This tap is suited for threading PG-standard conduit entry holes, commonly found in electrical enclosures, switchgear, and industrial panel fabrication. The plug chamfer style makes it appropriate for through-hole threading operations where a starter tap is not required. It is typically used by machinists, electricians, and panel builders who need to cut clean PG7 conduit threads in sheet steel or cast enclosure walls. The compact OAL of 70 mm fits standard tap holders and quick-change tooling systems.

Key Features

• PG7x20.00 thread form for PG-standard conduit fittings
• 4-flute spiral point geometry drives chips forward in through-hole cuts
• Cobalt HSS construction for improved heat resistance in harder materials
• Bright finish, suitable for use with cutting oil or water-soluble coolant
• Plug chamfer style eliminates the need for a separate starter tap in through-hole applications
• Right-hand cut, compatible with standard CW tapping setups

Compatibility

Designed as an OEM-style replacement spiral point tap for PG7x20.00 thread applications in through-hole tapping operations on steel and similar materials.

Installation Notes

Spiral point taps should be installed in a properly sized tap holder or quick-change adapter rated for the tap shank diameter before use. Ensure the workpiece is securely fixtured and the spindle is aligned perpendicular to the hole before starting the threading cycle. Apply cutting oil or an appropriate tapping fluid to extend tool life and improve thread finish. Power down and lock out all equipment before manually clearing chips or changing tooling.
