Product Overview
Size:
M14-2.00
Size:M14-2.00 The Dormer E252 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.
