How
We Produce Our High Quality Bits
|
 By now, anyone who knows woodworking, knows
CMT is the only orange one. CMT has been making
top quality bits for over 30 years and
are manufacturer of the original and only orange
router bit. CMT started as a small workshop
in the center of Pesaro, Italy and has become a global leader in
the production of woodworking tools. "CMT professional tools for wood" began
with Osvaldo Tommassini in 1964 in response to
the demands of the thriving furniture manufacturing
business in the area. Today, under the careful guidance
of the second generation of the Tommassini family,
CMT operates two factories in the Pesaro area
and distributes throughout the world.
Besides orange, CMT is
quality. CMT has a long-standing tradition of
producing only the highest standard in tooling.
Careful consideration is taken in all aspects of the
business – from the selection of raw materials, to the research and design
of each tool, to the technology and workmanship applied in production – right
down to the aesthetics of packaging and the promotion
of the name CMT.
RAW MATERIALS
FATIGUE
PROOF® STEEL
CMT router and boring bits start from solid bar
stock steel manufactured in the Von Moos Stahl
steelworks in Switzerland. Von Moos uses a hot
drawing process which is a process that pulls fibers of the
steel in one direction resulting in extra strong
and resilient bars. This provides a highly uniform
steel to machine the bits from – our router bit
bodies and shanks can withstand even the most
demanding mechanical and thermal stresses acting
as perfect shock absorbers during cutting.

CMT
carbide sample – note the uniformity of granules. They are
evenly distributed with no spaces or
granules outside the acceptable measures of
tolerance. An example of high quality
carbide.
Leading
European manufacturer of woodworking tools – notice the
large granules. This indicates the
use of recycled carbide powder which results in
oversized granules in the carbide.
A large granule in the carbide of the
cutting face edge can chip off, leaving a gap on the cutting edge
which causes
splintering when cutting.
Leading
American manufacturer of woodworking tools – note the dark gaps. This
is caused by an uneven distribution of cobalt in the manufacture of the
carbide, creating open spaces and making the carbide overly porous. The carbide
"crumbles" easier and wears down more quickly. |
CERAMETAL
TUNGSTEN CARBIDE
The carbide tips are the part of the bit that have the
job of actually cutting the wood. If the carbide is not made with the correct
formula, problems with edge life and sharpness will quickly evolve.
Carbide is made by creating a chemical compound between compressed carbide
powder, cobalt and tungsten.
The quality of the resulting carbide
depends on how uniform the granulates
are and how compactly they bonded with
the chemicals. (See photos) CMT uses a carbide composition specially
formulated
by Céramétal manufacturers in Luxembourg who produce
micrograin carbide according to our
carbide tip design specifications.
You are
guaranteed to get a long-lasting performance and multiple re-sharpenings from
your CMT carbide-tipped tool. |
