The Union Butterfield 1567(NPTF) uncoated, high-speed steel pipe tap has straight flutes, interrupted threads, and a round shank with a square end, and is used to create NPTF (National Pipe Taper Fuel) right-hand threads in a range of materials, with strength in carbon steel and alloy steel. NPTF thread, also called Dryseal American National Standard Taper Pipe Thread, is an ANSI-standard thread configuration designed for a leak-free tapered pipe joint that is created by an interference fit between engaged threads rather than by the use of sealants. The straight flutes are suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). Interrupted thread, caused by the removal of every other tooth except the first few chamfer threads, permits a larger supply of lubrication to reach the cutting teeth and assists with chip disposal.Right-hand threads are designed to tighten when a head or nut is rotated clockwise (the most common threading direction). High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials and provides an economical alternative to coated tools. The round shank with square end helps to minimize rotation in the tool holder. This tool can be used in machines, such as drill presses or lathes, or with hand tools such as tap wrenches.In the Union Butterfield 1567(NPTF) series, all taps have five flutes and semi-bottoming chamfers. This tap conforms to ANSI standards and is suitable for normal pipe thread tolerance.Taps produce internal threads in previously formed holes and can be used in machines (such as drill presses) or with hand tools. Common types of taps include hand taps, spiral point taps, spiral flute taps, thread forming taps, and pipe taps. Hand taps (straight-flute taps) collect chips in the straight flutes of the tool; spiral point taps push chips through holes ahead of the tool; and spiral flute taps pull chips back from the tip of the tool, up and out the hole. Thread forming taps, also known as cold forming taps, press rather than cut to create threads in a drilled hole, and no chips are created. Pipe taps create threads in pipes and pipe fittings. Each thread type designates a thread profile and each type is identified with an abbreviation. In the U.S. and Canada, the Unified Thread Standard is the dominant thread type, including UNC (Unified Coarse), UNF (Unified Fine), and NPT (National Pipe Taper) threads, among others.
