Guhring 9044025041660 Spiral Point Tap 8-32 Unc Cobalt

Product Description

The GUHRING 9044025041660 is a spiral point plug tap designed for through-hole threading in a wide range of ferrous and non-ferrous materials. It cuts an 8-32 UNC right-hand thread to a Class 2B/3B fit tolerance with an H5 thread limit, making it suitable for general-purpose fastener tapping where a controlled tolerance is required. The tap is manufactured from cobalt high-speed steel and carries an oxide finish to reduce friction and improve chip evacuation during cutting. With 3 flutes and a plug chamfer, it is intended for use in CNC machining centers, drill presses, and hand tapping operations where through-hole access is available. Licensed machinists, tool and die technicians, and maintenance mechanics are the primary users.

This tap is applied in through-hole threading operations across a broad spectrum of workpiece materials including aluminum, aluminum alloys, cast iron, free cutting steel, heat treatable steel, stainless steel, structural steel, sulfured steel, tool steel, and case hardened steel. The 8-32 UNC thread form is common in instrument panels, enclosures, electrical components, and light structural assemblies. The plug chamfer style provides a gradual lead-in that distributes cutting load across several threads, making it appropriate for both production runs and repair tapping.

Key Features

• 8-32 UNC thread form, right-hand cut, Class 2B/3B fit
• H5 thread limit for controlled tolerance threading
• Cobalt HSS construction for improved heat and wear resistance in hard and stainless materials
• Oxide finish reduces friction and aids chip flow in through-hole applications
• Plug chamfer distributes cutting load for smooth entry and reduced tap breakage
• 3-flute geometry supports efficient chip evacuation in through-hole configurations

Compatibility

Designed for through-hole threading in aluminum, aluminum alloys, cast iron, free cutting steel, heat treatable steel, stainless steel, structural steel, sulfured steel, tool steel, and case hardened steel. Series 4402 product family from GUHRING.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a tapping head, CNC rigid tapping cycle, or T-handle tap wrench. Ensure the workpiece is secured and the tap is properly aligned to the drilled pilot hole before applying torque. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Do not force the tap through a blind hole with this plug-style configuration; verify through-hole clearance before use.
