PROBLEM TO BE SOLVED: To provide a router capable of easily and accurately forming a slit to a plate-shaped panel along a core material, and a hole processing method capable of easily and accurately forming a through-hole having a shape conforming to that of the core material. SOLUTION: A plate material 8 is used by the route 1 equipped with a router main body 2, a first cutting blade part 3 provided to the leading end part of the router main body 2, a second cutting blade part 4 provided to the base end part of the router main body 2 so as to leave a predetermined interval with respect to the first cutting blade part 3, and a columnar body part 5 provided between the first cutting blade part 3 and the second cutting blade part 4. The hole 11 is formed to the plate material 8 by the first cutting blade part 3 and the router 1 is cut in its axial direction not only to bring the body part 5 into contact with the core material 7 but also to position the second cutting blade part 4 at the hole 11. Next, the router 1 is moved along the core material 7 while properly pressing the body part 5 to the core material 7 to allow the same to copy the core material 7 to easily and accurately form the slit 12 to the plate material 8 by the second cutting blade part 4. By this method, the through-hole having the shape along the core material 7 can be formed. COPYRIGHT: (C)2008,JPO&INPIT
