Dormer E201 Cobalt Steel Machine Straight Flute Threading Tap, Nitride Finish, Round with Square End Shank, Modified Bottoming Chamfer, M6-1.00mm Thread Size, 6.0mm Shank Diameter (Pack of 1)

The Dormer E201 nitride cobalt steel hand threading tap has straight flutes and a round shank with a square end, and is used to create metric right-hand threads in a number of materials including cast iron. The straight flutes are suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). The nitride finish offers increased hardness and wear resistance, and is good for working with abrasive materials. Cobalt steel is used for tough machining applications because it resists abrasion and high cutting temperatures and has higher feed rates compared to high-speed steel. Right-hand threads are designed to tighten when the head or nut is rotated clockwise (the most common threading direction). 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 with hand tools such as tap wrenches.All taps have modified bottoming chamfers. The tap is suitable for the 6HX tolerance class: 6HX is used for materials that do not cause oversize problems, such as cast iron.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.Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.
