The process of cutting or forming threads using a tap is called tapping, whereas the process using a die is called threading. A tap is used to cut or form the female portion of the mating pair. A die is used to cut or form the male portion of the mating pair.

Fluteless taps are used to form the internal threads without chip removal. In contrast to conventional tapping where material is cut from the work piece, thread forming is a preessure deformation process without chip removal for the production of internal threads. During the process the material is cold formed without interrupting the grain flow.

Designed for general purpose hand tapping or in production machines.

High Speed High Performance Spiral Point Taps are designed for through hole tapping in heat treated steels up to 45 RC, tough alloys, and stainless steels. They are manufactured with a reduced neck design specifically for use on CNC equipment. High performance tap increases production while decreasing downtime and inventory.
-
Nut taps, as the name implies, were designed for tapping nuts. Most large production nut tapping jobs are done with bent shank nut taps.
-
Pipe Taps for taping inside diameter of pipes.

Extension taps have an extended shank to reach inaccessible, long reach holes. The hub portion of pulley parts contain oil cups and set screw holes, most of which cannot be reached with ordinary hand taps. Pulley taps have the same basic thread dimensions as hand taps, but pulley longer shank. When tapping pulley hub holes, the taps are inserted through holes in the rims which are slightly larger than the shanks of the taps. These holes serve as guides or bushings to assure proper alignment.

Taps are used to produce internal screw threads in a pre-drilled or pre-punched hole.

-
Tap drill bits are drill and tap in one simple pass.

-
Tap extractors remove broken taps and save the threads without drilling, lasers, damaged threads, scrapped parts or repair inserts.

-
Wrenches designed for hand tapping, tap wrenches can also be used with other tools including screw extractors and drills.

-
Thread Mills were designed to cut high quality left or right hand threads in difficult to machine materials on a CNC Machine Center with helical interpolation. Internal and external threads can be cut with one tool and be more consistent than regular tapping.
