Abstract
A milling tool includes an elongate cutting head having a front end, a rear end, and a longitudinal axis extending therebetween. The cutting head includes a plurality of flutes separated from each other by a corresponding number of intermediate portions, wherein the flutes extend axially along the cutting head. The cutting head has a coolant distributing through-hole extending between two adjacent flutes through the intermediate portion located therebetween, for influencing the distribution of coolant provided to the milling tool.
Claims14
A milling tool comprising an elongate cutting head having a front end, a rear end, and a longitudinal axis extending therebetween, the cutting head including a plurality of flutes separated from each other by a corresponding number of intermediate portions, wherein the flutes extend axially along the cutting head, wherein the flutes are helical such that the flutes and the intermediate portions extend axially following a curved helical path around the longitudinal axis of the cutting head, the path deviating from the axis by a helix angle, and wherein the cutting head further includes at least one coolant distributing through-hole extending between two adjacent flutes through the intermediate portion located therebetween, wherein the coolant distributing through-hole is not directly connected to any axially extending internal coolant channel arranged for conveying coolant through the milling tool, and wherein the at least one coolant distributing through-hole comprises at least a first and a second through-hole extending between the same two adjacent flutes through the intermediate portion located therebetween, wherein the second through-hole is axially spaced from the first through-hole in a forward direction along the longitudinal axis.
