![]() We offer Cobalt-Vandium and High-Speed Steel (HSS) taps.Ĭoatings - A layer added to the cutting surface of a tool to improve hardness, surface lubricity, and improve tool life. Substrate - Material which the tool is made. General performance taps are for general use in lower volume work with slower speeds. ![]() Performance - High performance taps are designed for use on high speed machines in high volume manufacturing environments. The H limit from one size to the next increases in increments of. The limits are designated by the letter "H" for inch and "D" for metric, followed by a number. Tap Limit - or GH Numbers is a standardized system to indicate a level of tolerance for the thread outside the basic thread size of the tap. Forming taps Advantages compared to cutting taps: Forming is usually faster than ordinary thread cutting Deep threads down to 3. Class 1A and 1B have a loose fit for quick and easy assembly, 2A & 2B have a medium fit, and 3A & 3B have a close fit. Cutting taps With a cutting tap, the tap cuts the material, and chips are generated. ![]() Defined as A (screws - external), B (nuts - internal), H (metric screws - internal) and G (metric nuts - external). Roll forming taps also perform the best when the tap is centered and parallel with the hole. ![]() cut taps, as the same 10-32 thread requires a different size drill from a roll forming tap and a cut tap. Class of Thread - The standard identification system describing the tolerance and closeness of fit between hole and tap. These taps can be more costly, application specific, and require a different size drill vs. ![]()
