Product Announcement from SCT - Scientific Cutting Tools, Inc.


SCT Thread Mills-Image

Thread Mills cut a thread using helical interpolation. Helical interpolation involves moving three axes simultaneously. The X and Y axes move in a circular motion while the Z axis moves in a linear motion. This allows Thread Mills to cut both right and left hand
threads and to produce a variety of thread sizes (of the same pitch). All Thread Mills are made from premium sub-micron carbide (except for T15 Powdered Metal Thread Mills) and are stocked with or without a TiALN coating. They are ground on state-of-the-art
CNC tool and cutter grinders and have been engineered for high performance. Programming assistance is available.

Straight Flute Thread Mills:

Straight Flute Thread Mills are economical, offered in a large variety of sizes, and
excel in a large variety of materials. All the solid carbide straight flute thread mills
(except staggered tooth) are crest cutting and are for internal threads only.

Staggered Tooth Thread Mills:

Staggered Tooth Thread Mills have every other tooth removed in a staggered pattern.
This reduces the side cutting pressure in half while still cutting the entire form. All
staggered tooth thread mills will cut both internal and external threads and excel in
course pitches and difficult-to-cut materials.

Helical Flute Thread Mills:

Helical Flute Thread Mills are for high performance applications in all materials. The
30º helical flute allows for reduced side cutting pressure and will cut both internal and
external threads.

Valueline Helical Flute Thread Mills:

Valueline Helical Thread Mills have a 15º helical flute and cut internal threads only.
They are available only in the more popular sizes that allow for large production and
economy.

T15 Powdered Metal Thread Mills:

T15 Powdered Metal Thread Mills come with a TiCN coating. They are more break
resistant than carbide, excelling where rigidity is a problem. These tools will cut both
internal and external threads and should be run at about one third the surface feet per
minute of their carbide counterparts.

TMLR – Long Reach Thread Mills:

Long Reach Thread Mills have three teeth and a helical flute that provide reduced side
cutting pressure. The first tooth roughs, the second and third finish. This allows for
the efficient cutting of extremely deep threads in small sizes. These tools cut internal
threads only.

SPTM – Single Profile Thread Mills:

Single Profile Thread Mills have multiple flutes but only one thread form. This
provides the lowest possible side cutting pressure. It also allows for one tool to cut a
large range of thread sizes in both inch and metric. All SPTM’s will cut both internal
and external threads.
