Parlec 10-012N Tapping Adapter 1/8 Inch Pipe

Product Description

The PARLEC 10-012N is a quick-change tapping adapter designed for 1/8 inch pipe tap sizes within the NUMERTAP 100 Series tooling system. It accepts a tap shank diameter of 0.437 inches and a tap square size of 0.328 inches, providing a secure, repeatable drive connection during tapping operations. The adapter features a flange diameter of 1.18 inches and an outside shank diameter of 0.75 inches, making it a compact, rigid interface between the machine spindle and the tap. Machinists and tool crib personnel working with CNC machining centers or tapping machines will find this adapter integrates directly into NUMERTAP 100 quick-change tooling setups without requiring additional hardware.

This adapter is suited for production tapping applications where quick tool changes reduce cycle time. It is intended for use in machining environments running pipe thread tapping operations at the 1/8 inch pipe size. The NUMERTAP 100 Series is a standardized quick-change system, so this adapter fits into existing NUMERTAP 100 toolholders. It does not support coolant-through delivery. Typical applications include job shops, production floors, and maintenance machining operations requiring repeatable pipe thread tapping.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before changing or seating this adapter, ensure the machine spindle is powered down and locked out per applicable lockout/tagout procedures. Verify tap shank and square dimensions match the adapter specifications before assembly to avoid improper seating or tap slippage during operation. Consult the NUMERTAP 100 toolholder documentation for correct torque and retention procedures.
