WIDIA GTD Spiral Flute Tap: 1 1/2"-12 UNF, H5 / 3B, 5 Flute

A WIDIA GTD spiral flute tap is used for threading blind holes in materials like steel and stainless steel. Its spiral flute design pulls chips upward and out of the hole, preventing chip clogging and enabling clean, accurate threads in general-purpose machining applications.

The WIDIA GTD VTSFT-TC5121 is a 1 1/2"-12 UNF spiral flute tap with an H5 / 3B tolerance, 5 flutes, and a semi-bottoming chamfer. It is designed for threading blind holes to a Class 3B fit, ensuring precise thread depth and finish.

3G Electric supplies WIDIA GTD taps worldwide, handling full logistics and customs clearance for international delivery. As a global industrial sourcing partner, we provide genuine WIDIA GTD taps like the VTSFT-TC5121 to customers across 14 industrial departments, including machining and tooling.

Select a spiral flute tap with a semi-bottoming chamfer for blind holes, as it allows threading close to the hole bottom. Match the tap's thread size, pitch, and tolerance (e.g., 1 1/2"-12 UNF, H5 / 3B) to your workpiece material and required fit. WIDIA GTD taps are a reliable choice for general-purpose threading.
