Style
   Style       
   Your choices are...         
   Acme Thread Tap       Acme thread taps are used to produce a thread for an Acme screw.  Typical applications include rotary and transverse motion on machines. 
   Carbide Insert Tap       Carbide insert taps use solid carbide cutting face inserts, brazed to a hardened steel tap body.  They are an economical alternative to solid carbide taps. 
   Combined Drill and Tap       Combined drill and tap tools are used to drill and tap a hole in one process.  The lead end of the tool is shaped like a drill bit and the mid-section contains the threaded portion. 
   Extension Tap       Extended taps are made to the same specifications as standard taps, but contain an extended shank length for difficult to reach holes. 
   General Purpose / Hand Tap       General purpose taps, also referred to as hand taps, are used for general purpose or hand tapping applications.  Taps are available in taper, plug, and bottoming styles. 
   Interrupted Thread Tap       Interrupted thread taps have every other tooth removed in the thread helix.  The tooth removal allows coolant to reach the cutting teeth and helps to break the chips during the threading operation. 
   Nut Tap       As the name implies, nut taps are designed for cutting threads in nuts. Nut taps have a chamfer on the leading edge and a long shank diameter smaller than the minor diameter of the tap. This long shank allows for multiple nuts to accumulate when being tapped at the same time. 
   Pipe Tap (Straight)       Straight pipe taps are used for cutting a straight pipe thread. 
   Pipe Tap (Taper)       Tapered pipe taps are used for cutting a tapered pipe thread. 
   Pulley Tap       Pulley taps are used for tapping holes for set screws and oil cups in pulley holes.  Pulley taps are similar to hand taps, but have a longer shank as conventional hand taps may not be able to reach the hub due to interference with the pulley diameter. 
   Solid Carbide Tap       As the name implies, solid carbide taps are made of carbide and can achieve higher metal removal rates and longer tap life due to the structure of the carbide material. 
   Spiral Fluted Tap       As the name implies, spiral fluted taps have a flute that is made with spiral flutes instead of straight flutes.  The spiral shape assists in removing chips from the hole and also helps for cross-drilled holes and other holes with a gap.  Spiral taps come in two forms, regular (or slow) spirals and fast spirals.  Regular spirals have a 25-30i helix angle and fast spirals have a 45-60i helix angle. 
   Spiral Point Tap       Spiral point taps differ from standard hand taps in that they have a spiral shape for the first few threads.  The spiral point assists in the removal of chips prior to thread cutting, making them ideal for production through hole operations.  
   Tandem Acme Tap       Tandem Acme taps have two thread sections, the first being a roughing cut section and the second a finishing cut section.  This design allows an economical means to create an acme thread with one pass. 
   Thread Forming Tap       Thread forming taps are fluteless, lobed taps.  They form the thread by the process of extrusion, as opposed to cutting it, so do not generate any chips. 
   Trapezoidal Thread Tap       Trapezoidal thread taps are used in heavy load applications, such as presses, valves and jacks.  Trapezoidal taps are the same as Acme taps, except they are made with a 30 degree included angle. 
   Other       Other, unlisted or proprietary tap style.

   Chamfer Type (if applicable)       
   Your choices are...         
   Bottoming Tap       Bottoming taps, also referred to as finishing taps, contain a 1-2 thread-long chamfer are used to thread blind holes to the bottom. 
   Plug Tap       Plug taps, also referred to as seconding taps, contain a 4-6 thread-long chamfer and are used in through holes and blind holes that have sufficient clearance at the bottom. 
   Taper Tap       Taper taps contain an 8-10 thread-long chamfer that is used as a guide during initial thread cutting and to distribute the cutting over the maximum number of teeth.  Taper threads are used for through holes and materials that require a tapered guide.
