されている。(Prior Art) As shown in FIG. 7, a conventional cutting tool 1 includes a plurality of cutting bodies 3 fixed to a wire rope 2 at intervals. This cutting body 3 contains abrasive grains such as fine diamond particles, and is formed into a cylindrical shape. The cutting bodies 3 are sequentially inserted through the wire rope 2 and fixed by brazing or crimping.

ないと、切削体がずれて隣接する切削体どうしが
接触してしまう。そのため、切削具の切削性が悪
くなる。(Problems to be Solved by the Invention) However, in the conventional cutting tool, it was necessary to insert the cutting bodies one by one into the wire rope and fix them, so it took time and effort to manufacture the cutting tool. Furthermore, if the cutting bodies are not sufficiently fixed to the wire rope, the cutting bodies will shift and adjacent cutting bodies will come into contact with each other. Therefore, the cutting performance of the cutting tool deteriorates.

断する可能性がある。 Further, when the cutting tool is fixed to the wire rope by brazing, the brazing metal penetrates into the gap between the wire ropes and hardens the wire ropes. Therefore, the wire rope may break at the boundary between the hardened portion and the unhardened portion of the wire rope. Furthermore, when using this cutting tool, there is a possibility that chips and cooling water may enter the gaps between the wire ropes, causing the wire ropes to deteriorate and break.
それゆえに、この発明の主たる目的は、簡単に
製造することができ、その切削性が悪化しにく
く、かつ破断しにくい、切削具を提供することで
ある。 Therefore, the main object of the present invention is to provide a cutting tool that can be easily manufactured, has less machinability, and is less likely to break.
（問題点を解決するための手段）
この発明は、金属板または金属線を螺線状に形

に嵌まり込むようにコイル体の外周上に螺線状に
形成される切削体とを備えた、切削具である。(Means for Solving the Problems) The present invention includes a coil body formed of a metal plate or a metal wire in a spiral shape, and an abrasive grain formed on the outer periphery of the coil body so as to fit into a gap between the coil bodies. This cutting tool includes a cutting body formed in a spiral shape.
（作用）
螺線状のコイル体の隙間に切削体が螺線状に嵌
まり込む。(Function) The cutting body fits into the gap between the spiral coil bodies in a spiral manner.

的に加工することができ、その製造が簡単であ
る。(Effects of the Invention) According to the present invention, a cutting tool can be manufactured by spirally winding the cutting body into the gap between the spirally formed coil bodies, so that the cutting tool can be continuously processed. and its manufacture is simple.
さらに、コイル体の隙間に切削体が嵌まり込む
ようにして螺線状に形成されるため、切削体の間
隔がずれたりせず、切削体どうしが接触するよう
なことがない。そのため、この切削具の切削性を
保つことができる。 Furthermore, since the cutting bodies are formed in a spiral shape so as to fit into the gaps between the coil bodies, the intervals between the cutting bodies do not deviate, and the cutting bodies do not come into contact with each other. Therefore, the cutting performance of this cutting tool can be maintained.

たは数種混合してもよい。(Embodiment) FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line - of the embodiment in FIG. This cutting tool 10 includes a coil body 12. The coil body 12 is formed, for example, by spirally winding an elongated steel plate. This steel plate is
For example, it is formed to have a hexagonal cross section. By forming this steel plate in a spiral shape, a spiral gap 14 is formed on the outer peripheral surface of the coil body 12. A cutting body 16 is wound around the coil body 12 so as to fit into this gap 14. The cutting body 16 is made of an alloy containing abrasive grains such as fine diamond particles, for example.
It is formed into a linear shape with a circular cross section. This cutting body 16
contains, for example, 1 to 50% by volume of fine diamond particles of 20 to 400 meshes, and further contains 30 to 50% copper, 30 to 50% iron, and 5 to 10% tin as binders.
In addition to the above examples, as a binder, one or more of the following may be mixed: 30 to 50% nickel, 10 to 70% cobalt, 5 to 10% molybdenum, and 5 to 10% tungsten. .

物が切削される。ただし、この切削具１０はリン
グ状に形成されなくてもよい。この場合、切削具
１０は、その長手方向に往復運動させることによ
つて被切削物を切削することができる。 In this cutting tool 10, a coil body 12 is formed into a ring shape, and this is rotated like a chainsaw. Then, by applying the object to the rotating cutting tool 10, the object is cut by the cutting body 16. However, this cutting tool 10 does not have to be formed in a ring shape. In this case, the cutting tool 10 can cut the object by reciprocating in its longitudinal direction.
このような切削具１０では、切削体１６が隙間
１４に嵌まり込むため、切削体１６がずれたりし
ない。したがつて、切削具１０の長手方向に向か
つて、切削体１６の間隔を適当に保つことができ

ができる。さらに、切削体１６は、コイル体１２
の隙間１４に巻き付けることによつて連続的に製
造することができるので、切削具１０の製造を簡
単にすることができる。 In such a cutting tool 10, since the cutting body 16 fits into the gap 14, the cutting body 16 does not shift. Therefore, the distance between the cutting bodies 16 can be maintained appropriately in the longitudinal direction of the cutting tool 10. Thereby, the cutting performance of the cutting tool 10 can be maintained. Furthermore, the cutting body 16 is a coil body 12
Since the cutting tool 10 can be manufactured continuously by wrapping it around the gap 14, the manufacturing of the cutting tool 10 can be simplified.
この切削具１０では、第３図に示すように、切

好に保つことができる。 In this cutting tool 10, as shown in FIG. 3, when a part of the cutting body 16 comes into contact with the workpiece 18,
The cutting body 16 is pushed into the gap 14 of the coil body 12. Gap 1 into which the cutting body 16 is pushed
4 is pushed wider, and the width of the adjacent gap 14 is narrowed accordingly. As a result, the cutting body 16 fitted into the narrowed gap 14 is pushed up. In this way, as shown in FIG. 4, the cutting body 16 is uniformly pressed against the workpiece 18. Thereby, the cutting performance of the cutting tool 10 can be kept good.
なお、上述の実施例では、切削体１６を断面円

によつて、切削体１６がコイル体１２の隙間１４
からずれにくくなる。 In the above embodiment, the cutting body 16 is formed into a linear shape with a circular cross section, but as shown in FIG. 5, it may be formed into a plate shape with a hexagonal cross section. In this case, the inclined portion of the coil body 12 and the inclined portion of the cutting body 16 are formed so as to be in contact with each other. By forming the cutting body 16 in this way, the cutting body 16 closes the gap 14 of the coil body 12.
It becomes difficult to slip off.
また、第６図に示すように、コイル体１２を断
面円形の線状に形成してもよい。このように、コ

体１６が形成されていればよい。 Further, as shown in FIG. 6, the coil body 12 may be formed into a linear shape with a circular cross section. In this way, the coil body 12 and the cutting body 16 can be formed into any shape such as a plate shape or a linear shape with a circular cross section.
In other words, the cutting tool 10 only needs to have the cutting body 16 formed so as to fit into the gap 14 of the coil body 12 formed in a spiral shape.
また、上述の実施例では、切削体１６に含まれ
