摘要： An adjustable reamer includes a securing portion, a shank, a guide members, at least one cutting insert, an adjustment device for adjusting the insert, and a clamp for clamping the insert. The clamp is releasable from the shank. A first place of contact is created between the clamp and the shank, and a second place of contact is created between the clamp and the cutting insert. An angle between the first and second places of contact in relation to the rotational axis of the reamer is at least 100.degree., preferably larger than 135.degree..

摘要： A drill including a substantially columnar tool body having an axis. The tool body includes a pair of chip ejection grooves formed in an outer peripheral surface thereof. The tool body further includes, in a distal end portion thereof, a pair of cutting edges provided at respective distal ends of the pair of chip ejection grooves and a recess communicating with the pair of chip ejection grooves. The pair of cutting edges have radially inner ends located in positions slightly offset from the axis radially outward, and the recess extends along the axis while passing a gap between the radially inner ends of the pair of cutting edges, and has a bottom surface facing a distal end of the tool body. The bottom surface of the recess includes one slope and another slope. The one slope obliquely crosses the axis in a position aligned with the axis and inclines toward one of the pair of chip ejection grooves as the one slope proceeds to a side near a base end of the tool body, and the other slope crosses the one slope on a side near the distal end of the tool body and inclines toward another of the pair of chip ejection grooves as the other slope proceeds to the side near the base end of the tool body.

摘要： A drilling tool for drilling in metals has in its front part cutting insert-carrying cartridges, for instance 3, 5 or 7 in number. The peripheral cartridge (6) carries a peripheral cutting insert (7). This peripheral cartridge is fastened in the drill by a locking screw (16) that extends in a slot (17) in the drillhead. Radially inside of the peripheral cartridge is a wedge (15) which can be displaced axially and thereby regulate the radial position of the peripheral cartridge and cutting insert and, thereby, the cutting diameter. When the desired radial adjustment has been attained, the peripheral cutting insert is fixed by the locking screw (16). In this way, a very exact adjustment of the cutting diameter is obtained.

摘要： A metal cutting drill with replaceable cutting inserts and a length to diameter ratio of four to one or more. Two cutting inserts are positioned in exactly opposed diametric positions, and engage the workpiece in a substantially identical manner to precisely balance the radial forces resulting from drill axially advancing though a workpiece. Through the use of dual cutting inserts, the drill cuts the full circumference of a bore with each one-half revolution and therefore achieves the a faster axial feed rate. By virtue of the inserts being triangular, the curved corners on the cutting edges of the two inserts may be positioned relatively close together and yet sufficient space is left between the inserts to enable the drill shank between the inserts to be relatively thick and strong even at increased length to diameter ratios. Through the provision of a length to diameter ratio greater than four to one, the bores which the drill is able to produce are substantially deeper at any given diameter than those achievable by prior art indexable drills.

摘要： Reamers, when operated with large amounts of material removed and at high reaming speeds, encounter difficulties when they ream in material in which permanent structural changes occur on the application of heat and subsequent rapid cooling. These difficulties are avoided in that the transition region between the main cutting edge and the minor cutting edge follows a constantly curved path at least one end region of which runs tangentially to at least the minor cutting edge.

摘要： A drill for drilling in metal with improved performance in the smaller diameter range. The drill comprises a drill shaft, the front end of which is provided with radially outer and radially inner inserts, each insert having elongated rhomboidic shape, in which each of the short sides is broken at its middle to form a V-shape having an internal obtuse angle. The inserts are arranged such that the longitudinal axis of the radially outer insert is inclined at an angle from the longitudinal axis that is different from the angle of inclination between the longitudinal axis of the radially inner insert and the longitudinal axis of the drill.

摘要： Adjacent one end thereof the shank of a back spotfacing tool has therein a transverse slot, and a cutter mounting pin which extends between opposite sides of the slot parallel to the shank axis. A cutter has in one end thereof a U-shaped slot which is inserted removably over the pin to support the cutter for limited pivotal movement about the pin into and out of an operative position in which a flat, external, limit surface formed on the side of the cutter remote from the open end of its U-shaped slot engages the bottom of the slot in the shank to support the cutter for a cutting operation, and to prevent removal of the cutter from the pin. The cutter may be swung manually to an inoperative position in which the open end of its slot is positioned to permit removal of the cutter from the pin, or the replacement thereof over the pin.
