    摘要: Provided is a replaceable machining head wherein: fractures on the tool attaching portion do not occur; the production cost is minimized; the tool life of the working tool will be lengthened; and the head body is free from a risk of falling off during replacement. In the replaceable machining head, a cutting edge section is formed on the front side of a head body; a tool attaching portion to which a working tool is to be attached, is formed on the rear end side of the cutting edge section; tool attaching faces are formed in the tool attaching portion; the surface of the head body 1 is coated with a coating film; and the number of droplets or macro particles having convex shapes with a size of 0.3 μm to 5.0 μm, is 200 or less, per area of 40 μm×60 μm on the surface of the coating film over the tool attaching faces.

    摘要: An elongated drill bit has a shank at one end and working end at the other. A flute portion is between the working end and the shank. The flute portion is continuous with the shank and working end and is generally unitarily formed with them. The flute portion has at least one flute with a helix angle between approximately 30° and 35°. The working end has a pilot tip with a cutting portion. A tapered web is formed in the flute portion, a thickness of the web at the tip of the working end is about 9% to 15% of the nominal diameter.

    摘要: A bevel head replaceable rotary tool is provided. The rotary tool includes a coupling protrusion and a coupling recess, plural sets of serrations provided on an outer circumferential surface of the coupling protrusion and an inner wall surface of the coupling recess, circumferential abutting portions provided on the tool body and the bevel head, and axial tight-contact portions, provided on the tool body and the bevel head. The serrations of the coupling protrusion and the serrations of the coupling recess arranged such that curvatures of circumferential circular arcs of the serrations of the coupling protrusion are greater than those of the serrations of the coupling recess or the serrations of the coupling protrusion and the serrations of the coupling recess have circumferential circular arcs with centers deviated from each other.
