          The Parapara Drill has an original shape of breaker on the flute, resulting in a high chip breaking capacity and eliminating the problems of chip entrapment and residues.
          Contributes to the elimination of post inspection processes.
          No need to re-add the breaker and thus can easily be reground.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

          Background<\/strong><\/p>

          • Problems such as chips winding around, remaining on the workpiece\/jig and accumulating on the fixture occur during the drilling process.
            Regular cleaning and additional inspection processes are required.<\/li>
          • Conventional drills with nicks or breakers do not have sufficient chip breaking ability, and the breaker shape needs to be recreated for regrinding, which poses issues in \u201cversatility\u201d, \u201cchip breaking ability\u201d, and \u201cregrinding\u201d.
