Spiral-Point Flute for Through Holes |

Spiral Flute for Blind Holes |
Remove long, stringy chips to produce cleaner threads than standard taps. The flute design prevents buildup to protect the quality of the threads and avoid damage to the tap. Since you don’t need to reverse these taps to extract chips, they also create threads faster.
High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear for three times the life of uncoated taps.
Spiral-Point Flute for Through Holes—Push chips ahead of the tap and out of through holes. Also known as gun taps.
Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes. When tapping brittle material like iron that creates fine or powdery debris, choose a straight-flute tap.
Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.
Bottoming Chamfer—These taps have the shortest taper to thread close to the bottom of blind holes. They require the most force to turn, so they’re often used to finish holes started by plug-chamfer taps.
