摘要： Disclosed is a cutting tool, including: a cutting edge including a coating from a rake face to a flank face, and has a relief angle of not less than 15 degrees, a material of the coating having a higher wear resistance than a base material of the cutting edge, and during cutting of a work, an edge of the coating on the rake face at a top of the cutting edge is worn by friction with the work; with a progress of a wear inward in a radial direction, an edge of the coating on the flank face at the top of the cutting edge is removed by friction with the work to expose the base material thereunder; and the exposed base material is worn by friction with the work to retract the flank face inward in the radial direction.

摘要： The object of the invention is to stably spray cutting fluid in a good mist form, when cutting fluid and air are supplied from the surrounding area and cutting fluid is sprayed in a mist form from the tip end section of a rotary cutting tool. The rotary cutter of the present invention sequentially feeds a mixture of cutting fluid and air through a supply pipe 4, first supply path b in a cover 3, second supply paths c, d in a chuck 2, a hollow center cavity (front throttle chamber d, throttle 24a, and rear throttle chamber e) in the chuck, and a third supply path g in a rotary cutting tool 1. The first supply path and second supply path are intermittently connected when the respective openings thereof face each other as the cover and chuck turn relative to each other; the second supply path sprays fluid toward the throttle; the front throttle chamber is formed such the diameter thereof expands from the second supply path; the throttle is formed such that the diameter thereof is less than the smallest diameter of the second supply path; the rear throttle chamber is formed by the rear end surface of the rotary cutting tool and the inner conical surface on the down-flow side of the throttle when that rear end surface and inner conical surface on the down-flow side come in close contact with each other; and the front throttle chamber is formed such that the capacity thereof is greater than that of the rear throttle chamber.

摘要： A drill includes a cutting edge having a ridgeline. The ridgeline has a part of an ellipse and a straight line. It is assumed that the coordinates of a separation point of an ellipse portion from a straight line portion are (x0, y0). The straight line is a tangent to the ellipse at the separation point. It is assumed that a1 is an area from a tip end of the drill to x0, a2 is an area from x0 to the origin of the ellipse, and a3 is a negative area, along the x-axis. The ridgeline of the cutting edge is formed straight along the tangent in the area a1, and is formed along the ellipse in the area a2. A margin is formed in the area a3 continuously from a relief face of the cutting edge.

摘要： A drill includes a pair of main cutting edges extending from a distal portion of the drill to a position close to a proximal end of the drill to entirely define a two-edge configuration, and a pair of auxiliary cutting edges extending between positions at the distal and proximal sides of a maximum diameter position to partly define a four-edge configuration. A ridgeline of each auxiliary cutting edge is located within an angle smaller than 90° from a ridgeline of the corresponding main cutting edge toward the rear in a rotation direction of the drill. The point angle of the auxiliary cutting edges increases at a higher rate than the point angle of the main cutting edges in a predetermined range from the maximum diameter position toward a distal end of the drill.

摘要： This fastening tool supports a key wrench such that it cannot rotate at a location where a hexagonal hole on the tip end part comes in contact with a nut, so that even though the key wrench is pressed backward as a pin is screwed into the nut, a key wrench holder remains in a state of contact with the nut. After the pin has been screwed into the nut, the nut is twisted off at a weak section. The further the pin is screwed into the nut, the key wrench holder supports the key wrench at a location closer to the pin, which keeps the amount of torsional deformation of the tip end part of the wrench small, and thus makes it possible to securely engage with the pin, and in the final state of the fastening work, it is possible to completely twist off the twist-off type nut, which requires a large torque.
摘要翻译： 这种紧固工具支撑一个扳手，使得它不能在尖端部分上的六角孔与螺母接触的位置处旋转，使得即使当销钉被拧入螺母中时按压扳手， 钥匙扳手保持与螺母接触的状态。 销已拧入螺母后，螺母在弱部分扭转。 另外，销钉拧入螺母，钥匙扳手支架在靠近销钉的位置处支撑扳手，这样可以使扳手的前端部分的扭转变形量变小，从而可靠 与销接合，并且在紧固工作的最终状态下，可以完全扭转需要大扭矩的扭转型螺母。
