ACCUSHARP 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.
ACCUSHARP 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.
