Title: INDEXABLE, SINGLE-SIDED CUTTING INSERT HAVING TWO CLAMPING BORES AND CUTTING TOOL INCLUDING SUCH AN INSERT
Abstract:
A cutting tool (58) rotatable about a tool axis (AT), having a cutting body (60) and at least one indexable, single-sided cutting insert (20) removably secured in an insert receiving pocket (62) of the cutting body (60). The cutting insert (20) has opposing upper and lower surfaces (22, 24) with a peripheral side surface (26) extending therebetween and a central axis (AC) passing therethrough. First and second clamping bores (28a, 28b) extend between and open out at the upper and lower surfaces (22, 24). First and second primary cutting edges (30a, 30b) are formed at the intersection of the upper surface (22) and the peripheral side surface (26). The lower surface (24) includes first and second annular recesses (36a, 36b) communicating with the first and second clamping bores (28a, 28b), respectively, and first and second recess channels (44a, 44b) extending from the first and second clamping bores (28a, 28b), respectively, to the peripheral side surface (26). The first and second recess channels (44a, 44b) extend parallel to a longitudinal first plane (P1) containing the central axis (AT).
