Product Description & Reviews

The Union Butterfield 1580(M) uncoated, high-speed steel thread forming tap has a round shank with a square end and is used for cold-forming right-hand threads in ductile materials such as aluminum, brass, bronze, low-carbon steel, and leaded steel. It is suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). The Rol-Rite design reduces tapping torque. The spiral lobe pattern with no grooves makes this design especially suitable for interrupted holes and for through holes in thin sections. 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 provide an economical alternative to coated tools. The square end shank helps to minimize rotation in the tool holder. This thread forming tap can be used in machines such as drill presses or lathes. Union Butterfield 1580(M) taps are available with a variety of chamfers. This tap conforms to ANSI standards and this tool can create threads to a depth 2 ½ times its diameter. It is suitable for the ANSI 6H tolerance class: 6H is used for a normal length of thread engagement and medium tolerance quality. 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.
