Guhring 9029120041660 Spiral Flute Tap 8-32 Unc Ticn

Product Description

The GUHRING 9029120041660 is a spiral flute tap designed for blind hole threading in challenging materials, including titanium. It carries an 8-32 UNC thread form with a modified bottoming chamfer, making it well-suited for applications where threads must extend close to the bottom of a blind hole. The three-flute, right-hand spiral design evacuates chips up and out of the hole during the tapping cycle. A TICN (Titanium Carbonitride) coating improves wear resistance and reduces galling when cutting hard or abrasive workpiece materials. Built from powdered metal, the tap offers a fine-grain substrate that supports the demands of production threading environments.

This tap is intended for use in blind hole threading applications where standard taps fall short. The modified bottoming chamfer requires fewer lead threads before full-form threads begin, allowing threads to start closer to the bottom of the hole. It is sized for 8-32 UNC fastener applications common in light mechanical assemblies and precision components. The H4 and H5 thread limits and 2BX class of fit make it appropriate for tighter-tolerance threaded connections. This tool is typically used by machinists, tool-and-die makers, and precision fabricators working with CNC machining centers, drill presses, or tapping arms.

Key Features

• 8-32 UNC thread form with right-hand thread and right-hand flute direction
• Modified bottoming chamfer for threading close to the bottom of blind holes
• TICN coating for extended tool life in titanium and other abrasive materials
• Powdered metal construction for a fine-grain, wear-resistant substrate
• Three-flute slow spiral design promotes chip evacuation in blind hole operations
• H4 and H5 thread limits with 2BX class of fit for controlled tolerance threading

Compatibility

Designed for blind hole threading in titanium and similarly hard or abrasive materials. The 2BX class of fit and H4 and H5 thread limits suit applications requiring precise thread tolerance in 8-32 UNC blind holes. No specific machine or model compatibility was provided by the manufacturer for this item.

Installation Notes

This tap is installed and operated by qualified machinists following standard tapping procedures for the applicable machine tool. Always apply a suitable cutting fluid or tapping compound rated for the workpiece material before starting the tapping cycle. Ensure the spindle speed and feed rate are appropriate for the tap diameter and workpiece material to avoid breakage. Inspect the tap for wear or chip buildup between uses, and never force a tap into a hole that has not been properly drilled to the correct tap drill size.
