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 steel, stainless steel, gray cast iron, ductile cast iron, wrought aluminum, cast aluminum, copper and copper alloys |
Flood coolant |
2 to 3 pitch |
H5 thread limit |
