    • PROBLEM TO BE SOLVED: To provide a blade capable of enhancing the machining accuracy and the durability, and shortening the machining time. SOLUTION: A cutter 10 for tooth cutting is a machining tool used for cutting a tooth of a gear having a curved tooth trace such as a spiral bevel gear 13. The cutter 10 for tooth cutting has blades 14 and a cutter body 28 in which a plurality of blade holders to hold each blade 14 are circumferentially provided at equal spacing. Each blade 14 has a blade part 42 for simultaneously cutting tooth flanks 46a, 46b facing each other across a tooth groove 44 to be machined on its fore end, and the rake angle r of a rake surface continuous to the blade part 42 is set at 2-11°.

    • PROBLEM TO BE SOLVED: To provide a rotary cutting tool for gear cutting, surely preventing shifting of a cutter blade in a slot in machining for gear cutting to sufficiently heighten the cutting accuracy.
      SOLUTION: This rotary cutting tool A for gear cutting includes: a cutter fitting tool 1 provided with a plurality of slots formed at predetermined intervals on the outer peripheral surface; a plurality of cutter blades 2 respectively inserted in the slots of the cutter fitting tool; and a clamp ring 4 mounted on the outer peripheral surface of the cutter fitting tool to surround the cutter blade. Each slot has a first side wall surface 12a on the front side in the rotating direction R and a second side wall surface 12b on the rear side in the rotating direction, which are opposite to each other, and an inner wall surface 12c positioned at the innermost part between both side wall surfaces. The inner wall surface is provided to intersect the second side wall surface at an acute angle, and the rear face 2b and the inner side surface 2c of each cutter blade are formed to come into contact with the second side wall surface of the inner wall surface of each slot.
