The Widia Gtd VTSFT-TC5145 is a spiral flute tap designed for cutting internal threads. It features a #10-32 UNF thread size with a 2B class of fit and H5 thread limit. The tool is made from high speed steel with a black oxide coating. It has three flutes and a right-hand thread direction.

Machinists cutting #10-32 UNF threads in blind holes

This tap suits machinists producing #10-32 UNF threads in blind holes where chip evacuation is critical. The spiral flute geometry pulls chips upward and out of the hole. It is not for through-hole applications where a straight flute or point tap would be more appropriate. Buyers needing a different thread size, class of fit, or flute count should look at other tooling.

Three flutes and a 1/2 inch thread length

The three-flute design provides a balance of strength and chip clearance for the #10-32 size. The thread length is 1/2 inch within an overall length of 2 3/8 inches. The 75 percent thread drill size is #21. The tap handles standard production volumes in materials suited to high speed steel. It runs out in very high-volume runs requiring carbide or in materials needing specialised coatings.
