- Necked design in sizes #4 through 3/8 in improves coolant flow when threading deep blind holes
- Forming taps displace metal, comparable to external thread rolling, conventional cutting taps remove metal as chips that can clog the threaded hole
- Improved lobe groove design on machine screw sizes #5 and larger improves threading efficiency in blind hole applications
- Tapping speeds can be almost doubled above conventional cutting taps, improving efficiency of the forming action
- Applicable on wrought aluminum, cast aluminum, copper and copper alloys
- Flood coolant
- 0.438 in neck length
- 1.13 in flute length
- 2 to 3 pitch
