Product Description

WIDIA GTD General Purpose Thread-Forming Taps.

Frequently Asked Questions

What is the WIDIA GTD Thread Forming Tap 19872 used for?

The WIDIA GTD Thread Forming Tap 19872 is used to create internal threads in ductile materials such as steel, aluminum, and brass. It forms threads by displacing material rather than cutting, producing stronger threads with no chips. Common applications include automotive, aerospace, and general manufacturing where thread integrity is critical.

What are the specifications of the WIDIA GTD Thread Forming Tap 19872?

The WIDIA GTD Thread Forming Tap 19872 has a thread size of 5/16"-18 UNC, with an H5 tolerance class for 2B-3B fit. It features a bottoming chamfer for threading to the bottom of blind holes. The manufacturer part number is 19872, and it is designed for general-purpose thread forming in a range of materials.

Where to buy the WIDIA GTD Thread Forming Tap 19872 worldwide?

You can source the WIDIA GTD Thread Forming Tap 19872 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide reliable sourcing for this and other WIDIA GTD tooling.

How to select the correct WIDIA GTD Thread Forming Tap for a job?

To select the correct WIDIA GTD Thread Forming Tap, match the thread size (e.g., 5/16"-18 UNC) and tolerance class (H5 for 2B-3B) to your hole requirements. Choose a bottoming chamfer for blind holes or a plug chamfer for through holes. Ensure the tap is suitable for the workpiece material—forming taps work best in ductile metals like aluminum or low-carbon steel.
