Frequently Asked Questions

What is a WIDIA GTD spiral flute tap used for?

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, preventing clogging at the bottom of the hole, making it ideal for production tapping in machining and manufacturing applications.

What are the specifications of the WIDIA GTD #12-24 UNC tap?

The WIDIA GTD spiral flute tap has a #12-24 UNC thread, H3 / 3B tolerance, 3 flutes, and a semi-bottoming chamfer. It is made from black oxide cobalt for wear resistance. The manufacturer part number is VTSFT5039.

Where to buy WIDIA GTD taps in worldwide?

3G Electric supplies WIDIA GTD taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine WIDIA GTD cutting tools like the VTSFT5039 spiral flute tap to customers across 14 industrial departments.

How to select the right spiral flute tap for blind holes?

For blind holes, choose a spiral flute tap like the WIDIA GTD #12-24 UNC with a semi-bottoming chamfer to thread close to the hole bottom. Ensure the tap has a H3 / 3B tolerance for precision fit and use cobalt material for harder workpieces.
