    摘要： A router bit for use with a turning implement comprising a router bit body having a shank body adjacent a cutting body for forming a key hole in a work piece. The shank body has an outer surface configured to be received by the turning implement. The cutting body has a body portion that spans between a tapered head portion and a tapered end portion, the tapered end portion attached to the shank body. The tapered head portion has a plunge cutting surface that forms a first acute angle with the longitudinal axis. The shank body has a diameter that is smaller than the diameter of the tapered head portion. The tapered end portion has a diameter that varies along its length from the shank body to the tapered head portion to reduce breakage of the router bit body during use. A wing may be attached to the cutting body.

    摘要： A rotatable cutting tool is disclosed and includes an elongate body having a longitudinal axis, a proximal end and a distal end. The cutting tool further includes at least one helical flute extending over a cutting length of the elongate body, the helical flute having a first end and a second end. The helical flute includes a leading cutting wall having an edge, a trailing cutting wall having an edge, and a flute surface between the leading cutting wall and the trailing cutting wall, the flute surface including a curved surface portion including a constant radius from the longitudinal axis of the elongate body. The cutting tool further includes a plurality of reliefs evenly spaced along the leading and trailing walls of the helical flute, each of the reliefs forming a semi-circular cutout on the flute surface, and wherein the reliefs in the trailing cutting wall are longitudinally offset from the reliefs in the leading cutting wall.

    摘要： A disposable drilling and milling cutter for use with an NC or CNC machine tool and configured to be fed in a spiral manner includes a shank, a chip removing groove at one of a plurality of offset positions at one end of the shank, a blade seat at a distal end of the chip removing groove, and a disposable blade locked to the blade seat. The disposable blade has a cutting edge at each of its upper and lower ends, and each cutting edge has an irregular height and a notch. The wavy structural design of the disposable blade enables the disposable drilling and milling cutter to drill and mill in a sectioned manner, to break the drilling/milling chips automatically, and to perform intermittent processing.

    摘要： A cutting tool with asymmetric structures on cutting teeth has multiple toothed surfaces. Each of the toothed surfaces has multiple groove structures dividing a side edge of the toothed surface into the cutting teeth. Since the groove structures of the toothed surfaces are arranged in an asymmetric and complementary manner, contact areas between the cutting teeth on the toothed surfaces of the cutting tool and a workpiece are reduced. The cutting teeth on the toothed surfaces of the cutting tool are not worn and broken easily. When the cutting tool is used for cutting hard brittle material, machining quality, accuracy, and efficiency are enhanced.

    摘要： An end mill having a gash formed in a top portion of a flute. In a cross-section perpendicular to an intersecting ridgeline between an end cutting edge rake face and a gash bottom face of the gash, the gash bottom face and the end cutting edge rake face, and the gash bottom face and the gash wall face are respectively connected together by first and second connecting faces. The connecting faces have a form which either is a concave curve or a substantially concave curve formed with straight lines. A radius of curvature of the concave curve or the radius of a circle inscribed within straight lines forming the substantially concave curve about the front connecting face is larger than a radius of curvature of the concave curve or the radius of a circle inscribed within the straight lines forming the substantially concave curve about the second connecting face.

    摘要： It is an object of the present invention to effectively suppress the occurrence of burrs in machining of a fiber-reinforced composite material, etc., using an end mill. An end mill includes first cutting edges 4 which spiral in a direction defining a positive helix angle and second cutting edges 5 which spiral in a direction defining a negative helix angle, the first cutting edges 4 and the second cutting edges 5 being disposed at positions shifted in a circumferential direction. The first cutting edges 4 and the second cutting edges 5 are each configured to be continuous over an effective cutting edge length, and at a tool top, a phase angle P1 between one of the first cutting edges 4 and its adjacent second cutting edge 5 located toward the back in a tool rotation direction is set to be different from a phase angle P2 between the second cutting edge 5 and its adjacent first cutting edge 4 located toward the back in the tool rotation direction.
