Threading Tools

Machine Taps — SPPT (Form B)

Machine Taps SPPT Form B are spiral point, or 'gun', cutting tools designed with a specific cutting-edge geometry to propel chips forward in through-hole applications. The Form B designation indicates a 3-5 thread chamfer lead, which facilitates a gradual cutting start and ensures high thread concentricity. Used in CNC machining centers, these taps prevent flute clogging and tool breakage when threading high-strength alloys for industrial fastener preparation.
