Key Features

  • Spiral point tap pushes chips ahead of tool to reduce clogging
  • Spiral point tap with straight flutes for cutting threads in through holes
  • Titanium nitride (TiN) coating combines hardness with low friction for extended tool life and faster cutting
  • Relieved-style design with eccentric, full-pitch diameter thread relief for free cutting and reduced tool wear
  • Plug chamfer for easier starting and correct perpendicular alignment

Product Description

The Union Butterfield TN1534(UNC)/TN1534(UNF) high-speed steel spiral point tap has a relieved-style design, straight flutes, a titanium nitride (TiN) coating, 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 two different ANSI thread specification standards: UNC (Unified Coarse) and UNF (Unified Fine). The spiral point of this tap (sometimes referred to as a “gun tap”) pushes chips ahead of the tool and the straight flutes reduce clogging. Both characteristics make it suitable for threading through holes (extending through the workpiece). Titanium nitride (TiN) is a gold-colored ceramic coating that combines hardness with low friction for extended cutting tool life and permits faster cutting speeds than with uncoated tools. Relieved-style tap design reduces friction between the tap and workpiece for reduced tool wear. This tap features eccentric, full pitch diameter thread relief for free cutting and increased tool life. The plug chamfer distributes cutting to ease tapping at the beginning of the hole and to maintain correct perpendicular alignment with 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. 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 TN1534(UNC) and TN1534(UNF) tap series, all taps have plug chamfers and two flutes. This tap conforms to ANSI standards and can create threads to a depth 2 ½ times its diameter. It is suitable for the ANSI 2B tolerance class: 2B is an average quality fit for commercial and industrial fasteners.

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.

Precision Dormer manufactures cutting tools under the following brands: Precision Twist, Dormer, and Union Butterfield. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.
