Product Overview
Size:
M20-1.5
Size:M20-1.5 The Dormer MTT-X E094 powdered-metal steel thread forming tap has
a round shank with a square end, a gold oxide finish, and lubricant grooves,
and is used for cold-forming metric right-hand threads in a range of
materials. It is available in ANSI standard metric sizes and is suitable for
threading through holes (extending through the workpiece) and blind or
bottoming holes (with only one opening). Gold oxide is a low-temperature heat
treatment that reduces grinding stress within the tool. The lubricant grooves
on this thread forming tap create paths for coolant and lubricant to reach the
taper threads of the chamfer, where forming occurs. The tap’s modified
bottoming chamfer has additional length to reduce chip load, adds tool life in
difficult-to-machine materials, and permits higher tapping speeds. 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 thread forming tap can be used in
machines such as drill presses or lathes. In the Dormer MTT-X E094 series, the
taps are designed with varying numbers of lubricant grooves depending upon
size. All taps in this series have modified bottoming chamfers. This tap
conforms to ANSI standards and can create threads to a depth two-and-a-half
times its diameter. It is suitable for the 6HX tolerance class: 6HX exceeds
the standard tolerance to increase tool life in tapping high-strength or
abrasive materials that do not create oversize problems. 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.
