The Union Butterfield U1511 uncoated, high-speed steel nut-style hand threading tap has straight flutes, a taper chamfer, and a round shank with a square end, and is used to create right-hand threads in a range of materials. It is available in ANSI UNC (Unified Coarse) thread standard sizes. This straight-flute tap is suitable for through holes (extending through the workpiece) because of the extra long chamfer. The extended taper chamfer distributes the workload of this tool more evenly for long tapping runs. It eases tapping at the beginning of the hole and helps maintain correct perpendicular alignment with the workpiece for increased tool life. A nut-style tap has a relatively long shank that is smaller than the minor diameter of the threads it will create, to permit nuts to move off the threads of the tool and collect on the shank after each hole is tapped. 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 U1511 series, all taps have four flutes and taper chamfers. This tap conforms to ANSI standards and can create threads to a depth 2 ½ times its diameter. It is suitable for the ANSI 3B tolerance class: 3B produces close-tolerance fasteners that resist loosening. 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.
