- Thread forming taps have not flutes or cutting edge so it cold form rather than cut the threads
- Advantages include no chips to dispose of, stronger higher quality threads, increased tapping speeds, longer tap life and reduced tap breakage. Recommended for a wide variety of ductile materials
- Plug Style (4 threads tapered) for thru holes and blind holes with adequate depth. The longer taper lead is easier starting, requires less torque, produces less burr above the mouth of the tapped hole and increases tool life
- "Lube Grooves" for lubrication and venting in blind holes
- Tool life 3-4 times or more than cutting taps
- Made from premium high speed steel with ground threads
- Thread foam, right hand cut, square drive shank
- Tin Coated finish
- 100% Made in USA
