Widia Gtd VTSFT8006 Spiral Flute Tap 1/2"-14 NPT 4 Flutes pneumatic accessory

Thread-cutting tool for NPT pipe threads

The Widia GTD VTSFT8006 is a spiral flute tap designed to cut 1/2"-14 NPT threads in metal workpieces. It suits maintenance technicians and machinists who need to create or repair tapered pipe connections in workshop or field settings. The cobalt construction with black oxide finish provides wear resistance during hand or machine tapping operations. Right-hand cutting orientation matches standard threading requirements.

Consistent cutting through full thread depth

The four-flute spiral design evacuates chips efficiently while advancing through the 1 3/8 inch thread length. Cobalt substrate maintains edge integrity across the full 3 1/8 inch overall length during sustained use. The 75 percent thread drill size of 45/64 inch prepares the hole for proper thread engagement. Bottoming chamfer allows threading close to the bottom of blind holes without bottoming out prematurely.

Manageable heat and torque in normal operation

Cobalt material dissipates heat generated during the cutting process without requiring external coolant in many applications. Four flutes distribute cutting forces evenly, reducing vibration and noise compared to fewer-flute designs. Black oxide coating reduces friction between tool and workpiece during rotation. Power draw depends entirely on the driving tool and workpiece material rather than the tap itself.
