Union Butterfield 1994(UNC) High-Speed Steel Combination Drill and Tap, Round With Square End, Uncoated (Bright) Finish, #4-40 Thread Size Item Description Combination drill and tap creates holes and cuts threads in one operation for efficient tooling Spiral flute tap design pulls chips back from the tip of the tool and out of the hole to prevent clogging Designed for creating and threading through holes Available in UNC (Unified Coarse) or UNF (Unified Fine) right-hand thread options for different applications Round shank with square end helps to minimize rotation in the tool holder SPECIFICATIONS The Union Butterfield 1994(UNC)/1994(UNF) uncoated, high-speed steel spiral flute tap and drill combination has a round shank with a square end and is used to drill holes and create right-hand threads in a range of materials. The tool creates and threads holes in one operation. It is available in two different ANSI thread specification standards: UNC (Unified Coarse) and UNF (Unified Fine). Its 15-degree spiral flutes pull chips back from the tip of the tool, up and out of the hole to prevent clogging. This tool is suitable for use in through-holes (extending through the workpiece). 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 1994(UNC)/1994(UNF) series all tools have two flutes. This tool conforms to ANSI standards and can drill and create threads to a depth 1 ? times its diameter. It is suitable for the ANSI 2B tolerance class: 2B is an average quality fit for commercial and industrial fasteners. Combination drill and tap tools are designed to create holes and cut threads in one pass. 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.
