摘要： The reaming tool (2) comprises a cutting part (8) having a peripherally arranged reaming cutter (10) which, upon rotation about a center axis (4) of the reaming tool (2), defines a cutting circle (16) of nominal diameter (D1). The reaming tool (2) further comprises at least two peripherally arranged guide elements (12A, 12B), which lie on a guide circle (18) arranged eccentrically to the center axis (4) or having a larger diameter (D2) than the cutting circle (16). As a result of this measure, high surface quality is obtained, in particular even in soft materials, since the reaming tool is clamped in the direction of the reaming cutter (10).

摘要： A material removal tool including a housing body having an active portion, at least one seating surface for a cutting insert operatively positioned on the active portion, and a guide pad positioned in a cavity in a circumferential surface of the active portion is disclosed. The guide pad is radially adjustable between a first radial position and a second radial position by a differential pressure across the guide pad. The differential pressure is created by an actuation fluid supplied to one side of the guide pad. A method for removing material from a workpiece with the rotating material removal tool is also disclosed.

摘要： A bit structure for powered tools includes a shank action end at one end of a bit and a tool gripping section at another end. The shank action end has a conical directing portion formed by extending rearwards from a front edge of the shank action end. The directing portion is extended rearwards to form an expansion bore cutting section between the shank action end and the tool gripping section. The expansion bore cutting section has at one axial cutting edge formed at a length equal to or greater than the maximum diameter of the directing portion. The bit structure thus formed can simultaneously perform multiple functions of drilling holes, expanding holes and fastening screws faster with less time and effort.

摘要： A deep hole cutting apparatus has a chip-replaceable guide pad on a cutting head section. With the deep hole cutting apparatus, high machining accuracy can be obtained in a stable cutting status and the service life of the guide pad is lengthened. A guide pad (7) is formed on a circular surface (71a) whose outer surface forms a top ridge section (7a) along the center portion in the width direction, and the guide pad is diagonally attached to a cutting head section (10a) so that the leading end side of the tool is closer to the front side in a tool rotating direction (y) compared with the rear end side of the tool.

摘要： A cutting tool of the sort used for deep hole drilling has a cutting head mounted on a shank. The cutting head is formed asymmetrically with respect to a longitudinal axis and has at least one cutting edge. The cutting head has guiding segments that extend from a forward end to a rear end of the cutting head. Each of the guiding segments has a guiding pad in the periphery thereof. A forward end of the guiding pad lies on a cylindrical envelope defined by the cutting diameter of the cutting tool. A rear engagement portion of the cutting head is engaged with a forward engagement portion of the shank. The cutting head is made from sintered carbide powders and the guiding pads are integrally formed with the cutting head.
