| Features & Benefits | • International sizes • Use to machine tap in open or through holes in a wide variety of materials • Shearing action of the spiral point pushes the chips ahead of the cutting action to reduce loading of the flutes • Unique design offers greater strength for higher speeds and faster production • Taps are manufactured to a 6H tolerance • Plug style with 3-5 thread chamfer Due to material variability and machining conditions, taps rarely cut their own size. The thread size produced is usually larger, but can be smaller due to shrinkage. Tap manufacturers realised that to tap a specified class of thread, several different ground thread tap limits would be required. These limits represent small, defined variations in tap size. A numbering system was developed to designate each series of limits, but these limit numbers are not to be confused with the classes of threads • The thread tap limits are designated by the letter D (ground, high) above basic pitch diameter or U (ground, low) below basic pitch diameter |
