摘要： Provided is a step-shaped drill bit including at least two stepped cutting edges that are axially provided. A cutting edge of a first step from a tip is formed so as to satisfy at least one of the following conditions. That is, a number of blades is smaller, a point angle of the cutting edge is larger, or a clearance angle of the cutting edge is larger than that of cutting edges of a second and subsequent step(s). As a result, a thrust resistance during a perforation can be reduced compared with a case in which the first step cutting edge is formed such that the number of blades, the point angle of the cutting edge and the clearance angle of the cutting edge are the same as those of the second and subsequent step(s).

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： 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： The object of the invention is to provide a sleeve removal tool that is able to easily remove a sleeve from a tap without damaging the sleeve. The sleeve removal tool has a first fastening member and a second fastening member. The first fastening member has a first contact surface and inner screw section, and is formed in a cylindrical shape. The first contact surface comes in contact with the flange of the sleeve all around one ring shaped surface. An inner screw section is provided such that it protrudes in the axial direction from the first contact surface. The second fastening member has a second contact surface and outer screw section, and is formed in a cylindrical shape. The first contact surface comes in contact all around the other ring shaped surface of the flange.
