Frequently Asked Questions
What is a WIDIA GTD pipe and conduit thread tap used for?
A WIDIA GTD pipe and conduit thread tap is used to cut internal NPT threads in pipe fittings and conduit for leak-proof joints in plumbing, pneumatic, and hydraulic systems. Its semi-bottoming chamfer allows threading close to the bottom of a blind hole, making it ideal for industrial maintenance and fabrication.
What are the specifications of the WIDIA GTD VTSTR8303 thread tap?
The WIDIA GTD VTSTR8303 is a 1/4"-18 NPT pipe tap with 4 flutes, a semi-bottoming chamfer, and is made from cobalt for heat resistance and durability. It is designed for general-purpose threading in steel, stainless steel, and other ferrous materials, delivering clean, accurate threads.

How to select the right WIDIA GTD thread tap for NPT applications?
Select a WIDIA GTD thread tap based on thread size (e.g., 1/4"-18 NPT), chamfer type (semi-bottoming for blind holes, taper for through holes), and material. Cobalt taps like the VTSTR8303 suit harder materials. Always match the tap to the pipe schedule and use proper cutting fluid for thread quality and tool life.
