3 Trio-Cut Only Tool for 3 Applications Threa illing with Unercut Threa illing an rill illing are possible with the same cutter an the appropriate insert. The avantages are shorter machining times as well as a reuction in tool cost. mooth cutting action an reuce cutting forces guarantees long tool life, improve surface quality, as well as a lower machine loa. A Conical position of insert pocket guarantees stability of the tool shaft. Further avantages are the raially back groun threa profile, extremely high wege angle, a more stable cutting ege as well as a positive rake angle an coolant through the holer. ➊ Threa illing with Unercut rilling, rill milling, rill an threa milling in a soli material with only one cutting tool without any change of the insert or tool Range beginning from 4 x,0 Available pitches are: /,5 / 2 ength of threa up to 7 rilling/milling epth up to 30 ➋ Threa illing rilling, rill milling, rill an threa milling in a soli material with only one cutting tool without any change of the insert or tool Range beginning from 4 x,0 (Ø theoretical unlimite) Available pitches are: /,5 / 2 ength of threa up to 30 ➌ rill illing 3- machining: rilling an rill milling in soli material illing of grooves, pockets, offsets rill Ø from 2 bore epth max. 30 mooth cutting action by a left helical groun insert ore stability from raial groun clearance angle Even isplacement of cutting forces 49
