Iwaki / Japan, 20. April 2012 - The Tungaloy Corporation has now extended its exceptional milling line with the launch of the new DoFeed Series of Super High Feed milling cutters that guarantee remarkable productivity levels when rough machining steel, cast irons, stainless steels and superalloys.

Ideal for applications in the Die & Mold and general machining industries, the new DoFeed Series is available as an indexable endmill shank series with diameters that include 16 to 40 mm which accommodate two, three, four, five and six inserts respectively. For deep cavity machining the endmills with long shank are available with an overall length of 150, 160, 180, 200 and 220 mm. The long overhang of the series maintains its rigidity for deep cavity machining at high feed rates.

For higher metal removal rates, the DoFeed is also available as a Face Mill bore type cutter with 50, 63 and 80 mm diameters that hold five, six and eight inserts respectively. The high density inserts with a large inclination improve chip flow and reduce cutting forces to improve productivity and metal removal rates by over 50%. For deep cavity machining with the face mill series, Tungaloy offers a range of arbors with lengths including 100, 140, 150, 200, 205, 255, 257, 335 and 337 mm.

The negative type inserts with large rake angle reduce chatter and cutting forces to enable this new high feed series of cutters to be used on all types of machining centre. With double sided high density inserts with four cutting edges, the DoFeed offers extended tool life with its MJ & ML type chipbreakers. The MJ chipbreaker makes the DoFeed suitable for general machining applications on steel, cast iron and hard materials whereas the ML chipbreaker with a large rake angle has remarkable sharpness to reduce cutting forces when machining stainless steel and superalloys.

Incorporating Tungaloy's special surface technology “PremiumTec,” the new DoFeed is available in Tungaloy's AH725, AH130 and AH120 insert grades to provide the series with remarkable flexibility and capability. This enables the endmill range to conduct shoulder milling, slot milling, ramping, small depth plunging and helical feed drilling at phenomenal feed rates. Complementing the capabilities of the endmills, the larger face mill range is suitable for shoulder milling, small depth plunging, ramping and helical feed drilling of large holes and cavities. To support the extremely high feed machining of the DoFeed, the series offers through cutter air holes to remove the chips from the work envelope while ensuring the cutting edge maintains an optimal temperature while machining.
