    摘要: The hole drilling process is for drilling a hole on a supported tube sheet by using a first drilling tool that can drill a hole with a diameter smaller than that of a mounting hole that is to become a target hole, and a second drilling tool that can drill a hole with a diameter equal to the diameter of the target hole, the process including: a temporary hole drilling step in which a temporary hole with a predetermined depth set beforehand is drilled by moving the first drilling tool to a drilled position set beforehand; a hole measuring step in which a distance (S) between an existing mounting hole and the temporary hole; a drilled position correcting step in which the drilled position is corrected based upon the distance (S) between the mounting hole and the temporary hole.

    摘要: A drill bit comprises a plurality of cutting blades arranged circumferentially, the cutting blades having a cutting edge formed by a connecting ridge line between a cutting face and a flank; and a tip formed by coupling radially inner ends of the cutting edges to each other at a center portion of a bit tip end, wherein at least one of the cutting blades has a first flank and a second flank, wherein the first flank has a blade tip side flank close to the cutting edge and a base end side flank formed on the base end side of the blade tip side flank, and wherein a tilt angle α1 of the blade tip side flank 3a is smaller than a tilt angle α2 of the base end side flank 3b which is tilted toward the axial direction.

    摘要: A drill achieves a long tool life while improving a property for discharging chips. The drill includes: a columnar body which is rotated about an axis; a plurality of cutting edges each being formed at a tip end portion of the body; and a plurality of thinning edges each being formed in conjunction with the cutting edge nearer the axis by providing thinnings at the tip end portion of the body. At least one of the plurality of thinning edges is provided with a concave portion that is formed by cutting the thinning edge to be recessed in a semicircular shape toward the rear side in the rotational direction, and a center of the semicircular-shaped concave portion is provided on a line extended from the tip end portion of the thinning edge when viewed from a tip end direction of the body.

    摘要: A high speed drill bit is formed of a longitudinal body designed to rotate about a longitudinal axis. Each flute has a leading edge with a positive rake angle and a trailing edge with a neutral or negative rake angle. The bit cutting face is formed by surfaces and cutting edges that are asymmetrical with respect to each other.

    摘要: A drill for the insertion of a dental implant is disclosed. The drill includes a rotational drive portion in the form of a metal rod with a first end and a second end. The first end is connected to a drilling apparatus. The second end of the rotational drive portion is connected to an active cutting portion made of plastic overmolded on a second end of the metal rod. The drill further includes a metal insert portion coupled to the active cutting portion to serve as a sharp edge for the active cutting portion.
