Improvements in tool inserts and tools adopting such inserts.

摘要

Tool inserts, advantageously but not restrictively inserts for rotating tools. The inserts being formed of a cutting bit (11), bit clamping and locking cap means (12) and securement means (14) advantageously screw means. Projection means (25) provided in the tool head (29) are interferring partially with the cap means (12). Other projection means (23) provided in the cap means (12) are interferring partially with the securement means (14). One projection (23) is cooperating with the means (12,14) with which it interfers, to generate a lateral clamping force due to the effect of the centrifugal force.
