Spiral Point Tap for #8-32 UNC Threads

This Westward spiral point tap cuts internal #8-32 UNC threads in through-holes. The two-flute design pushes chips ahead of the cut, reducing clogging and breakage. It suits maintenance technicians and machinists who need reliable thread production in steel and non-ferrous metals.

H3 Limit with 3B Class of Fit

The H3 thread limit and 3B class of fit deliver precise pitch diameter control for standard fastening applications. A 3/4 inch thread length on a 2 1/8 inch overall body provides reach for typical hole depths. The bright, uncoated high-speed steel performs well in general-purpose cutting but lacks the wear resistance of coated tools for high-volume or abrasive materials.

Plug Chamfer for Through-Hole Work

The plug chamfer style is intended for through-holes or blind holes with sufficient clearance at the bottom. It is not suitable for bottoming operations where threads must extend close to the hole floor. Buyers needing to tap to the bottom of a blind hole require a bottoming-chamfer tap instead.
