Solid Carbide Thread Mills ? Reduced Tool Inventory. One Thread Mill Can Produce internal & external threads. left hand & right hand threads, different thread diameters of the same pitch and through hole & blind hole threads. ? Requires Less Power. Produce coarse pitches and large diameters on lower H.P. machines. ? Tough Threading Applications. Thread harder, difficult-to-machine & gummy materials that cause problems for taps. ? Helical Flutes for reduced cutting forces, improved thread qualtiy & increased tool life. ? Precision Threading. Control pitch diameter precisely via programming. Precision thread depth control & positional accuracy. Produce 100% thread heights. Produce full threads to within one pitch of a shoulder or blind hole bottom. ? Easily Removed if Broken. No need for EDM burn-out. ? 10% Micrograin Carbide offers higher cutting speeds, high rigidity, excellent hardness, wear resistance and heat resistance and long tool life. ? ALTiN - Alumimum Titanium Nitride is an excellent all-around coating that is especially recommended for high thermal stress applications including dry machining, abrasive materials and difficult-to-machine materials. Benefits include higher cutting speeds and longer tool life.
