Guhring 9048853190500 Spiral Point Tap 3/4-10 Unc Cobalt

Product Description

The GUHRING 9048853190500 is a spiral point plug tap designed for right-hand, through-hole threading in steel and similar materials. Built from HSS-E cobalt and finished with a GUHRING Ignator coating, it delivers improved wear resistance and heat tolerance compared to standard high-speed steel taps. The 3/4-10 UNC thread profile meets both 2B and 3B class-of-fit requirements, covering the most common tolerance ranges in general mechanical assembly. With a 4.252-inch overall length and a 1.299-inch thread length, the tap suits standard machine tapping operations in CNC machining centers, drill presses, and tapping heads. This is a production-grade tool intended for use by machinists, tool-and-die makers, and maintenance tradespeople working to UNC fastener specifications.

This tap is suited for through-hole applications in steel, where the spiral point geometry pushes chips forward ahead of the cut rather than backing them out. That forward chip ejection makes it particularly effective in production environments where cycle time and tool life matter. The Ignator coating reduces friction at the cutting edges, extending tool life in repetitive tapping cycles. The 4-flute configuration and H5/H6 thread limit support tight-tolerance threading where dimensional consistency across multiple holes is required. Typical applications include structural fabrication, general machining, and maintenance repair operations using 3/4-10 UNC fasteners.

Key Features

• HSS-E cobalt construction for improved heat and wear resistance over standard HSS
• Ignator coating reduces cutting friction and extends tool life in steel applications
• Spiral point geometry pushes chips forward, optimized for through-hole threading
• 4 flutes with H5/H6 thread limit for consistent dimensional accuracy
• Covers both 2B and 3B class-of-fit tolerance requirements
• Right-hand cut, 3/4-10 UNC — compatible with standard tap holders and adapters

Compatibility

Designed for through-hole threading in steel using the 3/4-10 UNC thread standard. Compatible with standard 3/4-inch tap holders, quick-change tapping heads, and floating tap adapters used in CNC machining centers and manual tapping setups. Verify spindle speed and feed rates are appropriate for the workpiece material before use.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling professional familiar with tapping operations. Ensure the tap holder is properly aligned with the pre-drilled pilot hole to prevent tap breakage or thread distortion. Disengage machine power and secure the workpiece before loading the tap into the holder. Use an appropriate cutting fluid or tapping compound for steel to support chip evacuation and reduce tool wear during the threading cycle.
