<p>PURPOSE: To efficiently suck the cut powder on a base to correspond to oblique cutting by attaching a dust sucking nozzle to the base even on either one of the left and right sides of a blade so as to position the suction port thereof in the vicinity of a cutting region. CONSTITUTION: A dust sucking nozzle 10 is formed in a left and right symmetric state and attached to a base 31 by engaging the hooking projections 14a, 14b on the leading end side of the nozzle with the left and right hooks 32a, 32b formed to both left and right side parts of the base 31. For example, when the dust sucking nozzle 10 is attached along the right-hand part of the base 31, the suction port 12 is turned downwardly at about 45 deg. in the vicinity of the cutting region of a blade B and the cut powder generated at a cutting region is directly sucked immerdiately after generation through the gap 21 formed between the right-hand side plate 20d of a protector 20 and the base 31. Therefore, the interference of the protector 20 and the base 31 is avoided even if a main body 30 is inclined at the time of oblique cutting by providing the gap 21 within the necessary min. range and, therefore, oblique cutting becomes possible.</p> |
