Widia Gtd VTSFT8006 Spiral Flute Tap 1/2"-14 NPT 4 Flutes pneumatic accessory
A spiral-flute tap that cuts 1/2"-14 NPT threads with four cobalt flutes and black-oxide finish
- Spiral flutes clear chips efficiently in blind holes
- 1/2"-14 NPT thread size fits standard pipe connections
- Cobalt construction resists wear during repetitive tapping
- 4-flute design distributes cutting load for smoother threads
- Black oxide finish reduces friction and prevents corrosion
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.

Questions about this item
How much heat does the VTSFT8006 tap generate during continuous pneumatic operation?
The cobalt spiral-flute tap cuts with a shearing action that reduces friction, so heat build-up stays low even during extended threading cycles.
What drive tool and drill bit must I already own to use the 1/2"-14 NPT tap?
You need a pneumatic tapping head or reversible air drill that accepts the tap shank, plus a 45/64 in drill bit for the 75 percent thread preparation.
Will the VTSFT8006 tap work reliably in older cast-iron or steel pipe fittings?
Yes, the cobalt substrate and black-oxide coating resist wear when cutting NPT threads in legacy ferrous materials, and the four-flute design clears chips in shallow holes.
