Key Features

  • Spiral point and straight flutes for cutting threads in through holes
  • Spiral point tap pushes chips ahead of tool to reduce clogging
  • Powdered-metal steel for performance approaching that of solid carbide tools, with the toughness and shock-resistance of high-speed steel
  • Hard lube coating for low friction, ideal for hard-to-machine materials that form long chips
  • Plug chamfer for easier starting and correct perpendicular alignment

Product Description

The Dormer MTT-X E046 powdered-metal steel spiral point tap has a round shank with a square end, hard lube coating, and a plug chamfer, and is used to create metric right-hand threads in a number of materials, with best performance in stainless steel and titanium. 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). Hard lube is a hard coating with low friction, ideal for working with difficult-to-machine materials that form long chips, like stainless steel. This tool’s 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). Powdered-metal steel offers performance that approaches that of solid carbide tools but with the toughness and shock-resistance of high-speed steel. 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 Dormer MTT-X E046 series, taps with nominal diameters of 3 mm to 10 mm have three flutes and taps with nominal diameters of 12 mm to 20 mm have four flutes. All taps in this series have plug chamfers. This tap conforms to ISO 529 standards and can create threads to a depth two-and-a-half times its diameter. It is suitable for the 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.

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.
