Product Description & Reviews

The Union Butterfield 1572(UNC)/1572(UNF) uncoated, high-speed steel hand threading tap has straight flutes and a round shank with a square end, and is used in copper, brass, bronze, aluminum, and magnesium to tap oversized thread that will receive a helical coil wire screw thread insert (STI). It is available in two different ANSI thread specification standards: UNC (Unified Coarse) or UNF (Unified Fine). The straight flutes are suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). An STI is used to replace stripped, damaged, or weakened internal threads and are oversized so they can tap threads that will receive a helical coil wire screw thread insert of the same nominal size and pitch. Right-hand threads are designed to tighten when the 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 makes it suitable for hand or power-driven applications. 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 1572(UNC) series, machine screw sizes 4 to 10 and nominal-diameter 1/4” taps have three flutes; nominal diameters of 5/16” to 1/2” have four flutes. In the 1572(UNF) series, machine screw size 10 and nominal-diameter 1/4” taps have three flutes; nominal diameters of 7/16” and 1/2” have four flutes. These taps are available with a variety of chamfers. This tool conforms to ANSI standards and can create threads to a depth 1 ½ times its diameter. It has an ANSI 3B tolerance rating: 3B produces close-tolerance fasteners that resist loosening, as in aerospace applications. 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. Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.
