Frequently Asked Questions

What is a WIDIA GTD Thread Forming Tap used for?

A WIDIA GTD Thread Forming Tap creates internal threads by cold-forming material rather than cutting it. This 1/4"-28 UNF tap is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the WIDIA GTD Thread Forming Tap 19871?

The WIDIA GTD Thread Forming Tap MPN 19871 has a 1/4"-28 UNF thread size, H4 / 2B-3B tolerance class, and a bottoming chamfer. It is designed for through or blind holes and produces threads without chips, reducing breakage risk.

Where to buy WIDIA GTD Thread Forming Tap 19871 worldwide?

3G Electric supplies the WIDIA GTD Thread Forming Tap 19871 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this precision threading tool.

How to select the correct thread forming tap for a job?

Select a thread forming tap based on material type, thread size, and tolerance. For the WIDIA GTD 1/4"-28 UNF tap, ensure the hole diameter matches the recommended pre-drill size for forming taps. Use cutting fluid to reduce friction and extend tool life.
