Document Type and Number:
Japanese Patent JP2000500076
Kind Code:
A
Abstract:
The present invention relates to a tool that includes a tool body (12) and a cutting head (11) detachably mounted thereon. The tool is rotatable about a longitudinal center axis. The tool body (12) includes flutes formed in an outer surface thereof, and a pair of forward projections (60) at a front end thereof. The cutting head (11) includes front flutes formed in an external side thereof, and a pair of recesses extending circumferentially in communication with respective ones of the front flutes. To connect the cutting head (11) to the tool body (12), the cutting head (11) and tool body (12) are converged longitudinally so that the projections (60) enter the front flutes. Then, relative rotation is produced between the cutting head (11) and tool body (12) to align the front flutes with the rear flutes while causing the projections (60) to enter the recesses (50) and form therewith a bayonet coupling. The invention also relates to a method of mounting a cutting head (11) to a tool body (12) to form a metal-cutting rotary tool.
