Hertel R132056 Nut Tap 5/16-18 Unc 4 Flute Hss

Product Description

The HERTEL R132056 is a straight-flute nut tap designed for cutting internal threads in nut blanks and through-hole applications. Built from high speed steel with a bright finish, it cuts 5/16-18 UNC threads across a 1-13/16 inch thread length and a 5-1/2 inch overall length. Nut taps are designed to allow threaded workpieces to pass completely through the tap without backing out, making them well suited for high-volume production threading. Machinists and tool-and-die technicians are the primary users of this tool in shop and production environments.

This tap is suited for threading nut blanks, through-holes, and similar workpieces in ferrous and non-ferrous metals where a 5/16-18 UNC thread form is required. The 4-flute configuration provides balanced cutting action and chip clearance during threading. Its bright finish means no coating treatment has been applied, which works well when cutting fluids are used to manage heat and extend tool life. Typical applications include production machine shops, maintenance and repair operations, and toolroom use.

Key Features

• 5/16-18 UNC thread form for standard unified coarse thread applications
• 4-flute design provides balanced cutting and chip evacuation in through-hole work
• High speed steel construction offers good wear resistance across a range of metals
• Bright finish compatible with most cutting fluids and lubricants
• 5-1/2 inch overall length with 1-13/16 inch thread length supports nut-style pass-through threading

Compatibility

Designed as a standard nut tap for through-hole threading operations requiring a 5/16-18 UNC thread form in production and general machining applications.

Installation Notes

This tap is installed in a tapping head, tap wrench, or CNC spindle by a machinist or toolroom technician. Secure the workpiece before beginning the threading operation and apply an appropriate cutting fluid to reduce heat and extend tap life. Inspect the tap for wear or damage before each use, as a chipped or dull tap can damage the workpiece and create unsafe conditions. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating tapping equipment.
