Regular or Long Length Coarse Pitch Single End Mills for General Purpose Roughing Applications. Get excellent results with TTC's HP series of single-end roughing mills. The HP series is made from M42 cobalt for use in harsh industrial conditions. 8% Cobalt is added to increase the overall tool hardness. These single-end roughing mills are being offered in multiple flutes (3/4/5), knuckle flute design, round profile with a 30-degree helix angle. The tool characteristic is non-center cutting and used for side milling, peripheral, and slotting. The lower 30-degree helix angle wraps the tool slowly and improves the chip evacuation rate. HP series single-end roughing mill from TTC is available in 8 different sizes ranging from 3/16 inch to 1 inch. The overall length of HP single-end mills is available in different unusual lengths ranging from 2-3/8 inches to 5-1/2 inches. All TTC products are globally sourced and meet standard ANSI tolerances and requirements.
