  • Hand threading tap with straight flutes cuts threads in through holes and blind holes
  • ISO 529 standard tap creates threads for metric applications
  • Left hand threads help prevent loosening in applications involving counterclockwise rotation
  • High-speed steel for compatibility with a variety of materials
  • Round shank with square end allows tap to be used in hand or power-driven applications

The Dormer E501 uncoated, high-speed steel hand threading tap has straight flutes and a round shank with a square end, and is used to create metric left-hand threads in a range of materials. The straight flutes are suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). Left hand threads are designed to tighten when the head or nut is rotated counterclockwise; they are useful to prevent loosening in applications where the assembly will rotate counterclockwise.

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 Dormer E501 series taps with nominal diameters of 3 mm to 12 mm have three flutes and those with nominal diameters of 14 mm to 24 mm have four flutes. All taps are available with a variety of chamfers. This tap conforms to ISO 529 standards and can create threads to a depth 1 ½ 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.
