Abstract
A tool for rotary chip removal machining includes a cutting head, a retention element and a shank. The cutting head and the retention element comprise overlapping hooks for mounting the cutting head in the shank. The cutting head comprises two integral major cutting edges, each major cutting edge including a substantially straight edge and a convexly curved edge. The convex edge is disposed ahead of the straight edge and extends radially therebeyond.
Claims13
A cutting head for rotary chip removal machining, the cutting head defining an axis of rotation and having a front end and a rear end and comprising a rear mounting portion having a surface adapted for engagement by a retention element, and at least one and no more than six integral major cutting edges disposed at said front end of the cutting head, each major cutting edge including a straight portion extending in a generally front-to-rear direction, and a convexly curved portion disposed ahead of the straight portion and projecting radially from said axis of rotation therebeyond, the entire convexly curved portion being disposed in a single plane.
A cutting head for rotary chip removal machining, the cutting head defining an axis of rotation and having a front end and a rear end and comprising a rear mounting portion having a surface adapted for engagement by a retention element, and at least one and no more than six integral major cutting edges disposed at said front end of the cutting head, each major cutting edge including a straight portion extending in a generally front-to-rear direction, and a convexly curved portion disposed ahead of the straight portion and projecting radially from said axis of rotation therebeyond, the convexly curved portion having a curvature extending for greater than ninety degrees, whereby a portion of the curvature faces rearwardly.
A cutting head for rotary chip removal machining, the cutting head defining an axis of rotation and having a front end and a rear end and comprising a rear mounting portion having a surface adapted for engagement by a retention element, and at least one and no more than six integral major cutting edges disposed at said front end of the cutting head, each major cutting edge including a straight portion extending in a generally front-to-rear direction, and a convexly curved portion disposed ahead of the straight portion and projecting radially from said axis of rotation therebeyond, the convexly curved portion being curved about a center of curvature spaced radially outwardly from the axis of rotation.
