PROBLEM TO BE SOLVED: To provide a boring tool which improves dust suction performance and can perform comfortable boring work without contaminating a work place. SOLUTION: A rotor 10 into which a tip tool 2 can be inserted and which is engaged with the periphery of the tip tool 2 is installed in a dust suction cover 16. During boring, the rotor 10 follows the tip tool 2 and is rotated so that an air current is generated in a specified direction of the periphery of the tip tool 2. COPYRIGHT: (C)2006,JPO&NCIPI
