Claims

[Scope of Claim for Utility Model Registration] (1) In a deep hole cutting device that attaches a polygonal throw-away tip to a drill head, mounting seats for attaching the tip are provided at two locations, one in the axial direction and the other in the radial direction perpendicular to this. At the same time, these are formed into right-angled stepped portions, and correspondingly, at least two sides in the axial direction and the radial direction of the polygonal chip are formed into right-angled mounting surfaces, and the right-angled mounting surfaces A deep hole cutting device comprising: seated on the above-mentioned right-angled step. (2) Claim 1, further comprising a protrusion protruding from the drill head parallel to the axial mounting seat of the drill head and pinching the periphery of the axial mounting surface of the tip.
The deep hole cutting device described in Section 1. (3) The deep hole according to claim 1 or 2, wherein an adjustment bolt that protrudes radially from the axial mounting surface of the drill head and comes into contact with the axial restraint surface of the chip is screwed through the drill head. cutting equipment.
