Roughing End Mills - Cobalt and High Speed Steel

 Cobalt and High Speed Steel

Regal Cutting Tools manufactures a variety of roughers for a wide range of materials and conditions.  Heavy cuts can be achieved  because our roughing end mills have a much higher effective feed per tooth than a conventional end mill. Normally a 20% reduction in effective horsepower is used.  Roughers have chip-breaker cutting edges, the “peaks” on each cutting edge provide the cutting action producing short fat chips rather than long stringy chips produced by conventional mills. The “corncob” form is offset on each flute  which results in a relatively smooth milled surface.

Regal roughers remove more metal in less time than other types of end mill. Our tools can take heavier cuts at higher speeds with less chatter and vibration.  The tooth form, both coarse and fine pitch,  provides excellent heat dissipation during heavy cutting operations, making the tool especially effective for cutting high tensile steels. Regal engineers perfected the sine wave design which produces small controllable chips.  Our form relieved design can be easily resharpened with no change in tooth profile.

We offer a variety of styles including coarse and fine pitch in high speed and cobalt steels and similar styles in carbide.  Some carbide are offered with AlTiN coating as standard and all our high speed and cobalt roughers  can be coated with a variety of enhanced coatings.

Roughing Cobalt End Mills
Cobalt roughers resist abrasion and can withstand higher heat at high cutting speed.
