摘要： PROBLEM TO BE SOLVED: To provide an end mill with a coolant hole enabling the efficient cooling of a bottom edge and the rake face thereof and also enabling the injection direction of a coolant to be maintained even when the bottom edge is re-ground or re-polished.SOLUTION: A chip discharge flute 4 and an outer peripheral edge 5 which are twisted around the axis O of an end mill body 1 are formed on the top end outer periphery of the end mill body rotated about the axis O. A gash 6 and a bottom edge 7 are formed at the top end of the chip discharge flute 4. A coolant hole 8 twisted in the direction opposite to the outer peripheral edge 5 is formed in the end mill so as to extend from the gash 6 toward the rear end of the end mill body 1. A lead Lh (mm) of the coolant hole 8 has the relation of following formula 1 with respect to a lead Lp (mm) of the outer peripheral edge 5, a radius R (mm) of the bottom edge 7, a number Z of edges of the bottom edge 7, and an integer N of one or more.

摘要： PROBLEM TO BE SOLVED: To reliably hold a cutting head 10 without damaging a holder 1.SOLUTION: The holder 1 is made of cemented carbide alloy, wherein a fitting part 4B having a taper shape is formed at an attaching hole 4, and a distal end surface 2B is perpendicular to a central line O. The cutting head 10 is also made of cemented carbide alloy, wherein an attachment part 12 having a taper shape protrudes from a rear end surface 11C perpendicular to the central line O of a cutting edge part 11. The cutting head 10 is attached to the holder 1 by screwing female and male thread parts 3E, 13 to fit the attachment part 12 to the fitting part 4B so that the distal end surface 2B and the rear end surface 11C abut against each other. An inner-outer diameter ratio d/D1 of an inner diameter d of the fitting part 4B before the fitting to an outer diameter D1 of the distal end of the holder 1 is 0.5 to 0.8. An outer diameter expansion rate (D2-D1)/D1×100 (%) defined by the difference D2-D1 between the outer diameter D2 of the distal end of the holder 1 after the fitting and the outer diameter D1 relative to the outer diameter D1 is in a range of 0.022×d/D1-0.003 (%) to 0.33×d/D1-0.06 (%).

摘要： PROBLEM TO BE SOLVED: To provide a holder for a head-replaceable cutting tool which is manufacturable inexpensively, can be separated and collected, does not cause breakage and chatter vibration since the strength and rigidity are high, and can perform machining with high precision, and to provide a head-replaceable cutting tool.SOLUTION: This holder 1 for a head-replaceable cutting tool constitutes the head-replaceable cutting tool in which a replaceable cutting head 10 with an edge part 11 is detachably fitted to a mounting hole 4. A cylindrical connection member 3 made of a metal material lower in hardness than a holder body 2 is stored in the mounting hole 4 formed in the holder body 2. A recess is formed in the inner peripheral surface of the mounting hole 4. The connection member 3 is engaged with the recess since the outer peripheral surface thereof is fitted closely to the inner peripheral surface of the mounting hole 4. A mounting screw part 3E which is screwed with a head side screw part 13 formed on the replaceable cutting head 10 is formed in the connection member 3.
