Dormer E053 Cobalt Steel Straight Flute Tap, For Cast Iron, TiAlN Coated, Rou...
Product Overview
Size:
M16-2
Size:M16-2 The Dormer MTT-X E053/MTT-X E054 cobalt steel hand threading tap
has straight flutes, a round shank with a square end, a modified bottoming
chamfer, and a titanium aluminum nitride (TiAlN) coating, and is used to
create metric right-hand threads in a range of materials, with best
performance in cast iron and thermosetting plastics. It is available in two
different thread specification standards: Metric Coarse (M) or Metric Fine
(MF). The straight flutes are suitable for threading through holes (extending
through the workpiece) and blind or bottoming holes (with only one opening).
The TiAlN coating resists heat better than titanium nitride (TiN) and titanium
carbon nitride (TiCN) coatings, increasing tool life and performance. It also
offers increased hardness compared to TiN and may reduce the need for
lubricants based on the application. The modified bottoming chamfer has
additional length to reduce chip load, add tool life in difficult-to-machine
materials, and permit higher tapping speeds. Right-hand threads are designed
to tighten when the head or nut is rotated clockwise (the most common
threading direction). Cobalt steel is harder and tougher than high-speed
steel, so it helps increase tool life and it can be used to tap tougher metals
such as cast iron, nickel alloys, austenitic stainless, and aircraft alloys.
The round shank with square end makes this tap 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 MTT-X
E053/MTT-X E054 series, MTT-X E053 taps are available in M sizes; MTT-X E053
taps with a nominal diameter of 3 mm have three flutes and all other sizes
have four flutes. MTT-X E054 taps are available in MF sizes and they all have
four flutes. All taps in both series have modified bottoming chamfers. This
tap conforms to ISO 529 standards and can create threads to a depth 2 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.
Features
Hand threading tap with straight flutes cuts threads in through holes and blind holes
Titanium aluminum nitride (TiAlN) coating lubricates the tap for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than titanium nitride (TiN) and titanium carbon nitride (TiCN) coatings
Available in Metric Coarse (M) or Metric Fine (MF) right-hand thread options for different applications
Cobalt steel is harder than high-speed steel, for increased tool life and for tapping tougher metals
Modified bottoming chamfer has additional length to reduce chip load, add tool life, and permit higher tapping speeds
