PROBLEM TO BE SOLVED: To provide am implement for properly cutting the end faces of resin tubes regardless of the diameter of the resin tube, the cutting implement being usable for the resin tubes of a plurality of types having different diameters.SOLUTION: On the front surface 2a of a block body 2, tube insertion openings 4 and 5 having different diameters are formed. On the rear surface 2b of the block body 2, a recessed section 8 for releasing chips to partially expose the tip sections 4a and 5a of the tube insertion openings 4 and 5 is formed. In the recessed section 8 for releasing chips, a cutting blade 3 is fitted such that the cutting edge 3a thereof crosses the exposed portions 4b and 5b of all the tube insertion openings 4 and 5. The resin tube 10 inserted into the tube insertion opening 4 and the block body 2 are relatively rotated to cut the end face of the resin tube 10 to a flat and smooth surface 10b orthogonal to the tube axis by the cutting blade 3, and the cutting chips 10c are released to the recess part 8 for releasing the cutting chips. |
