Disposable cutting tip clamp for a milling machine

A disposable cutting tip clamp mechanism arranged such that a disposable cutting tip having a hole formed at the center thereof to enable a screw to pass therethrough is seated on a tip-mounting seat disposed on a tool main body, a tip-mounting screw is inserted into the hole of the disposable tip for fixing the tip by locking a head portion of the tip mounting screw to the hole, characterized in that:

• the tip-mounting seat has a seat bottom surface on which the tip-mounting screw hole is formed, and tip-positioning wall surfaces extend steeply from said seat bottom surface for positioning the disposable tip;
• a mounting hole is formed in the seat bottom surface of the tip-mounting seat;
• a screw member having a screw hole at a head portion thereof is threadedly connected with said mounting screw hole, with the head portion projecting from the seat bottom surface of the tip-mounting seat;
• the hole through the disposable tip has an engaging portion into which the head portion of said screw member is inserted and engaged;
• said screw member being disposed off-center toward the tip-positioning wall surfaces with respect to the hole of the disposable tip;
• and
• the tip-mounting screw fixing the disposable tip by being threaded with the screw hole in the screw member.
