LMT-Fette has long been recognized as a premier supplier
in the HSS and powdered metal
end mill market. Now, LMT-Fette is pleased to announce
the introduction of our first solid
carbide end mill product for the North American market,
our new AIR LINE® Solid Carbide
end mill. This unique end mill, some of which have “coolant-through” capability,
for roughing and finishing in non-ferrous materials, as
well as finishing in steel, stainless
steel, and nickel-based alloys.
The AIR LINE® Solid Carbide end mill is designed
primarily for use in roughing and finishing
of non-ferrous alloys such as aluminum, magnesium, brass,
etc. The AIR LINE® geometry,
with its unique “stepped-relief,” 20° rake
angle, and dead-sharp cutting edge, allows for
trouble free slotting and shouldering, even in softer
aluminum alloys. This geometry combined
with LMT-Fette’s new super-fine grain-grade substrate,
provides unmatched, economical
removal rates in all non-ferrous materials.
The AIR LINE® product also performs exceptionally
in finishing applications on more difficult
materials that benefit from a positive, up-sharp geometry.
This geometry, when combined
with our PVD TiAlN coating, also performs excellent in
finishing of low-carbon steels,
austenitic stainless steel, and nickel-based alloys.
The versatile design of the AIR LINE® Solid Carbide
end mill performs even the most difficult
end milling operation with ease.
The AIR LINE® Solid Carbide end mill is generally
designed for materials commonly used in
the Aerospace industry, especially aluminum and magnesium
alloys. However, the AIR LINE® end
mill has also shown exceptional versatility and excellent
performance in brass, copper,
and finishing of 300 series stainless steels and nickel-based
alloys such as Inconel and
The primary advantage of the AIR LINE® Solid Carbide
end mill is its ability to run at 50%
higher feed rates, leading to shorter machining times,
specifically when combined with“
coolant-through” capability. The slow-helix design
of the tool, combined with the “steppedrelief,” leads
to excellent edge strength, while maintaining a positive,
Additionally, the AIR LINE’s® unique “coolant-though” capability
leads to simplified chip
removal, thus improving process reliability.
