General purpose forming tap
Emuge Corp has introduced MultiTap
TM
-
Form, a high performance forming
tap designed to deliver performance
increases in a wide range of materials
including carbon steel, steel alloys,
stainless steel, aluminium, copper,
brass and bronze.
In
lab
tests,
MultiTap-Form
demonstrated four times the life
compared to a leading brand form
tap. MultiTap-Form is also designed
to produce threads within both 2B
and 3B classes of fit, eliminating the
guesswork of calculating H-limits.
“MultiTap-Formwillsignificantlyimprove
thread quality and boost output while
reducing production costs,” said Peter
Matysiak, president of Emuge Corp.
“One high performance MultiTap-Form
will handle most common materials
and applications. MultiTap-Form also
eliminates the need to stock numerous
types of taps that are suitable for
forming applications.”
The forming tap features an innovative
geometric design, a proprietary grade
of high speed steel (HSS-E) and is
TiN coated for exceptionally long life
and versatility. A short chamfer lead
of 1.5 to 2 pitch is suitable for bottom
tapping, and lubrication grooves allow
coolant flow-to-form action for holes
requiring long thread length.
The forming of threads offers many
advantages over conventional thread
cutting. A formed thread is one where
the material has been displaced instead
of cut, which provides excellent thread
surface quality and increased static
and dynamic strength of the thread.
Additional benefits include eliminating
the risk of poor threads due to axial
‘mis-cutting’ and the ability to increase
tapping speeds.
“OurMultiTap line is the result of collective
years of Emuge’s extensive tapping
expertise, application research and a
challenge the company
issued to its engineers to
design a multi-purpose
tap,” commented Mr
Matysiak. “Emuge design
engineers responded by
choosing a select base
material, along with
special geometry and
surface treatment that
would work in as many
common materials and
applications as possible.”
All MultiTap-Form taps
are made with Emuge’s
trademark long shanks, which are DIN
length, designed for extra reach. Tap
sizes include a range for UNC or UNF
threads, from #4-40 to
3
/
8
-24" sizes,
to metric sizes from M4 x 0.7 to M10
x 1.5.
Emuge is offering a performance
guarantee: if the MultiTap-Form tool
does not successfully outperform
the user’s current form taps in most
common materials, the tool purchase
will be fully refunded. MultiTap-Form is
available through Emuge distributors.
Emuge Corp is a subsidiary of Emuge-
Werk Richard Glimpel GmbH & Co
KG. The company manufactures an
extensive line of taps, thread mills,
end mills, holders and attachments,
with over 100,000 items sold through
distributors worldwide. Emuge offers
end-user technical support through
a network of in-the-field engineers
and in-house product specialists, all
with extensive tooling and application
experience.
Over 10,000 types of cutting tools
and accessories are stocked in
the company’s North American
headquarters located in West Boylston,
Massachusetts. The 21,000ft
2
facility,
custom-designed and built in 2005,
also serves as a technology centre,
equipped with a 5-axis CNC machine,
and featuring a showroom and
classroom.

Taper stress joint development
Chevron, Exxon, Shell, Statoil and
Petrobras are working with Magma
Global to develop and qualify a taper
stress joint using Magma’s m-pipe
®
technology. m-pipe’s high strength
and flexibility together with its fatigue
performance, corrosion resistance and
temperature performance make it an
attractive option for this demanding
riser application. The project, which
officially commenced in mid-February,
will focus on a 15ksi 8" taper stress
joint, and aims to have qualified design
by conclusion of the programme.
m-pipe is a high performance pipe
for riser, jumper, spool and flowline
applications. It was designed to
meet the particular challenges
of deep water and high pressure,
high temperature and sour service
operating environments. Magma has
developed a manufacturing process
that produces high performance
carbon/polymer pipes, that it claims
offer improved reliability, increased
performance, lighter weight and longer
life than conventional un-bonded
flexible pipe or steel solutions.
