Abstract

PURPOSE: To use ceramic or heat-resistant thermet as the material of a keeper for preventing said keeper from getting quickly worn down by chips and from losing the chip press-fastening capacity thereof for a short period of time during high-temperature cutting operaton.
CONSTITUTION: A keeper 4 for fastening a chip on a bite holder 2 is made of the ceramic or heat-resistant thermet that is superior in high-temperature wear resistance to retain the chip 1 press-fastening capactiy thereof for a long period of time while prevented from wearing down in a short period of time during high-temperature chip 1 cutting operation. Said keeper 4 is fitted on a bite holder 2 by means of a fixing bolt 7 with a soft metal washer placed between said bite holder 2 and fixing bolt 7 to hold said chip 1 fixedly on the anvil 3 of said bite holder 2. Thus, said keeper 4 can be prevented from failing due to the stress concentration thereon when fitted.
