    摘要： A cutting tool has a rake face and a flank face. The flank face is provided with a coolant supply hole. A ridgeline between the rake face and the flank face forms a cutting edge. An outer shape of the coolant supply hole in a cross section orthogonal to an axis includes a first portion facing the cutting edge, and a second portion opposite to the cutting edge when viewed from the first portion. The first portion has a concave portion extending toward the second portion. The concave portion is defined by a first side portion and a second side portion facing each other, and a bottom continuous with both the first side portion and the second side portion. In the cross section, an angle formed by a tangent of the first side portion and a tangent of the second side portion is not more than 160°.

    摘要： The purpose of the present invention is to provide a grinding tool capable of continuing machining in a dry state and of being manufactured in a short time and at low cost, and a manufacturing method therefor. For said purpose, a grinding tool (10-1) for grinding a workpiece comprises: a threaded helical groove (12) formed on the circumferential surface of a cylindrical metal head section (10b); ridgetop surfaces that result from the formation of the helical groove (12) and are formed so as to protrude with a trapezoidal cross-sectional shape; and abrasive grain surfaces (18) formed by winding an insulating resin rope in the helical groove (12) to mask the inside of the helical groove (12) and fixing abrasive grains on the ridgetop surfaces. The helix angle of the helical groove (12) with respect to the axial direction of the grinding tool (10-1) is set to be at least 80° and less than 90°.

    摘要： The wear of a flank face of a long bottom blade of the tip of an end mill body is effectively minimized, and chips produced by the long bottom blade are smoothly discharged. Bottom blades (9) are formed at ridgelines where gashes (7) and tip flank faces (8) intersect, the gashes (7) being formed at the tips of a plurality of chip discharge grooves (4) that are formed in an end mill body (1). At least one of the bottom blades (9) serves as a long bottom blade (9A) that extends toward an inner peripheral side longer than the remaining bottom blades (9B, 9C). Coolant holes (10) are formed between the chip discharge grooves (4) within the end mill body (1). A coolant hole (10A) that is located between a chip discharge groove (4A) of a gash (7A) along which the long bottom blade (9A) is formed and a chip discharge groove (4C) that is located behind the chip discharge groove (4A) in a rotational direction (T) of the end mill is open to the tip clearance face (8A) of the long bottom blade (9A). A coolant hole (10B) which is located between the chip discharge groove (4A) of the gash (7A), along which the long bottom blade (9A) is formed, and a chip discharge groove (4B) that is located in front of the chip discharge groove (4A) in the rotational direction (T) of the end mill is open to the gash (7A) of the long bottom blade (9A).
