Guhring 9010600079380 Spiral Point Tap 5/16-24 Unf Ticn

Product Description

The GUHRING 9010600079380 is a spiral point plug tap designed for through-hole threading in demanding materials, including superalloys and titanium. Built from high-speed steel (HSS) powdered metal with a titanium carbonitride (TiCN) finish, this tap delivers extended tool life in high-wear applications. It cuts a 5/16-24 UNJF right-hand thread to a 3BX class of fit and carries an H3/H4 thread limit. With 4 flutes and a plug chamfer, it is suited for production threading where chip evacuation and thread accuracy are critical. Licensed machinists and toolroom technicians are the primary users.

This tap is intended for through-hole threading operations in ferrous and non-ferrous workpieces, with a specific material application rating for superalloys and titanium — materials common in aerospace, defense, and precision manufacturing environments. The plug chamfer style allows it to start easily in through-holes. Its spiral point geometry pushes chips ahead of the cut, making it effective in CNC tapping centers and manual machines running through-hole applications at controlled feed rates.

Key Features

• TiCN coating increases surface hardness and reduces friction for longer tool life in superalloys and titanium
• Spiral point geometry pushes chips forward, ideal for through-hole threading
• Plug chamfer provides reliable thread start and gradual load distribution
• 4-flute design balances chip evacuation with thread form support
• H3/H4 thread limit and 3BX class of fit for precision thread accuracy
• Right-hand cut, no coolant-through requirement, no interrupted thread profile

Compatibility

Designed for through-hole threading of 5/16-24 UNJF threads in superalloys and titanium workpieces. Part of the GUHRING Series 1060 tap line.

Installation Notes

This tap should be installed and operated by qualified machinists or toolroom technicians familiar with tapping operations. Always secure the workpiece and verify spindle alignment before engaging the tap. Use an appropriate tapping fluid or cutting oil rated for the workpiece material to preserve tool life and thread quality. Follow machine manufacturer feed-rate and RPM guidelines for the material being threaded — do not force the tap or back it out without reversing spindle direction.
