摘要： Provided is a thread-forming tap for reducing machining torque and improving tool service life. A thread-forming tap (10) for plastically deforming the surface-layer section of a prepared hole to form a female thread by causing a margin section (18) of a screw thread (16) to bite into the surface-layer section of the prepared hole formed in an object to be machined, the tap being provided with a screw thread (16) formed in the shape of a male thread while a margin part (18) provided protruding in the radial direction and a release part (20) with a diameter less than the margin part (18) are arranged in alternating fashion, wherein the margin part (18) is formed in a udgeline shape with a width dimension of 0 at least at the bottom (30) of the screw thread (16), whereby the contact surface area onto the object being machined can be minimized during machining, machining torque can be reduced, and tool service life can be improved.

摘要： Since a pair of first spiral flute 24 and second spiral flute 26 disposed in a drill main body 12 of an indexable drill 10 is subjected to a hardening heat treatment and then mirror-finished through cutting by ball end mills 30 and 32, friction of flute inner surfaces is reduced and chips are favorably discharged. This suppresses wear, blade chipping, breakage etc., due to clogging of chips and improves durability (tool life) even in a deep hole machining indexable drill 10 having longer flute length L. An increase in cutting resistance due to clogging of chips is suppressed so that stable hole machining can be performed, and limiting machining conditions for enabling the hole machining are alleviated so that a machinable range is expanded.

摘要： Providing a formed rotary cutting tool that restrains occurrence of breakage. At least a first valley portion 44 as a neck portion in which a cutting edge diameter of a peripheral cutting edge 38 is locally minimized is provided with a roughing portion 58b as a fine roughing portion that is different in characteristics from a roughing portion 58a provided in a portion or portions other than the above-described at least the first valley portion 44. For example, where the roughing portion 58b provided in at least first valley portion 44 has characteristics that make cutting chips small, it is possible to restrain clogging of the cutting chips in at least first valley portion 44 and accordingly to advantageously restrain occurrence of breakage. That is, it is possible to provide the christmas-tree cutter 30 capable of restraining occurrence of the breakage.

摘要： Provided is a drill such that a sufficient amount of cutting liquid fed through a cutting liquid feeding hole is ensured without lowering the rigidity of the drill and without increasing the cutting liquid feeding pressure. The cutting liquid feeding hole (22), which is formed within a fluted portion (16), has a fan-shaped cross section which is enclosed by: a forward-side inner wall (FH) located forward relative to the direction of rotation (RT) of the drill (10) and along a radial direction thereof; a rearward-side inner wall (RH) located rearward relative to the direction of rotation (RT) of the drill (10) and along a radial direction thereof and facing the forward-side inner wall (FH) in a circumferential direction; an outer-circumference-side inner wall (OH) which is formed from a partial cylindrical surface centered on the central line (C) of the drill (10); and an inner-circumference-side inner wall (IH) which is formed from a partial cylindrical surface which is centered on the central line (C) of the drill (10) and has a curvature radius (R2) smaller than the curvature radius (R1) of the outer-circumference-side inner wall (OH), said inner-circumference-side inner wall (IH) facing the outer-circumference-side inner wall (OH) in a radial direction. Since the cutting liquid feeding hole (22) has the abovementioned fan-shaped cross section, sufficient web thickness can be ensured while the speed of the cutting liquid inside the cutting liquid feeding hole (22) can be increased without having to increase the cutting liquid feeding pressure, thereby increasing the amount of cutting liquid fed.

摘要： By screwing a threaded shaft (24) provided on a tip (14) into a threaded hole (26) provided on a body (12), the tip (14) is detachably installed on the body (12). Additionally, a restraining part (40) of the tip (14) is fitted into a restraining hole (38) provided in the body (12) and the body (12) and the tip (14) are positioned to be concentric with the shaft center (O). As a result, a separate installation screw is unnecessary and the tool is configured from two parts, the body (12) and the tip (14). Therefore, high centering precision is easily obtained. Additionally, the cross-sectional areas of the respective parts increase and strength increases, variation in tool life is limited, and excellent tool life can be stably obtained. Moreover, because the surface (24f) of the tip of the threaded shaft (24) is pressed to adhere closely to the bottom surface (26f) of the threaded hole (26) and the tip (14) is fixed to the body (12) to form a unit, a compressive stress acts on the threaded shaft (24) and the tip (14) can be fastened to the body (12) with a higher fastening strength than when a tensile stress is in operation.

摘要： [Object] Providing a ball endmill that is capable of restraining its vibration thereby permitting a cutting operation to be performed at an increased feed rate with an increased depth of cut and leading to an improvement in efficiency of the cutting operation. [Measures for achieving the object] A ball endmill 1 is constructed such that each ball-nosed end cutting edge 6a-6c includes first and second portions 6a1-6c1, 6a2-6c2 having respective first and second radii R1, R2 of curvature which are different in value from each other. This construction causes a cutting resistance (cutting torque) exerted by the workpiece 20 to radially act in a direction that is different in the first and second portions 6a1-6c1, 6a2-6c2 of each ball-nosed end cutting edge 6a-6c. Consequently, a feed rate and a depth of cut can be increased whereby the cutting efficiency can be improved.
