摘要： In one aspect, the invention relates to a support pad intended for metal machining drills and of the type that comprises an outside (19), an inside, front and rear end surfaces (21, 22), as well as a pair of spaced-apart side surfaces (24), between the outside (19) and at least the front end surface (21) a convexly arched entering surface (27) being formed that extends between, on one hand, a pair of front and rear borderlines (28, 29), the rear one (29) of which borders the outside (19), and, on the other hand, two tangentially spaced-apart side borderlines (30, 31). According to the invention, the rear borderline (29) of the entering surface (27) has the shape of a convex arc line as viewed in planar view toward the outside, more precisely an arc line the crest (36) of which is facing forward. In such a way, the position of the contact of the support pad with a hole wall can be predetermined in an exact way.
In another aspect, the invention also relates to a drill body equipped with one or more support pads.

摘要： The present invention provides a hole drilling process and a drilling tool. The hole drilling process is for drilling a hole on a supported tube sheet (45) by using a first drilling tool (63a) that can drill a hole with a diameter smaller than that of a mounting hole (60) that is to become a target hole, and a second drilling tool (63b) 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 (60A) with a predetermined depth set beforehand is drilled by moving the first drilling tool (63a) to a drilled position set beforehand; a hole measuring step in which a distance (S) between an existing mounting hole (60) and the temporary hole (60A); a drilled position correcting step in which the drilled position is corrected based upon the distance (S) between the mounting hole (60) and the temporary hole (60A); and a target hole drilling step in which the target hole is drilled by moving the second drilling tool (63b) to the corrected drilled position.

摘要： A deep hole drilling machine employing an external system for supplying coolant to a drilling portion in which high drilling efficiency can be achieved even if the drilling hole is deep by enhancing the discharge performance of chips from the drilling portion without setting the supply pressure of coolant at a high level. A tubular boring head (2) having discharging openings (4a, 4b) communicating with a chip discharge passage (10) on the edge (3a-3c) side is attached to the distal end of a hollow boring bar (1) having interior serving as the chip discharge passage (10), bypass holes (5,...) are provided at a plurality of circumferential positions in the circumferential wall (21) of the boring head (2) to penetrate obliquely such that the outer opening (5a) is located closer to the distal end side of the head than the inner opening (5b), and a part of coolant supplied externally to the drilling portion side flows through the bypass holes (5,...) into the boring head (2), thus generating attraction force to the discharge side and accelerating discharge of the chips (S).

摘要： The present invention relates to a tool and a cutting portion for cutting machining, wherein the tool in operative position preferably rotates about its longitudinal center axis. The tool comprises a tool body (12), a cutting portion (10) and a pull rod (11), said tool body having a front surface and said cutting portion having a support surface provided to dismountably abut against each other. The body has a shank portion (40). The front surface and the support surface comprise cooperating projections and recesses, which are provided to substantially alone transfer the cutting forces appearing during machining. The invention also relates to a separate tool tip, a cutting portion, a tool body as well as to a method for manufacturing a tool tip or a cutting portion.
