とするガンリーマ。A carbide blade body 2 is provided at one end of the pipe 1, and a pair of flute grooves 3 and a guide pad 4 extending in the axial direction are provided on the outer peripheral portion of the carbide blade body 2, respectively.
Moreover, in a multi-stage gun reamer configured such that the diameter of the cutting edge increases in stages so that the diameter of the machined hole can be increased in stages, a composite tip 5 is provided in the blast material portion of each cutting edge of the flute groove 3. In addition, these composite chips 5 are mounted on a carbide support piece 7,
The cutting edge layer 8 is made of a polycrystalline sintered body of diamond, cubic boron nitride, etc., and is sintered and fixed under ultra-high pressure and high temperature to form a two-layer structure. A gun reamer characterized in that the width of the margin 9 is smaller than the width of the corresponding guide pad 4.
