A tool includes a parent body (12) and at least two cutting inserts (14) fastened directly or indirectly to the parent body (12). A central clamping device (30) is configured to clamp the cutting inserts (14) in an oriented position relative to the parent body (12). An assembly includes the tool (10) and a jig (32), which can accommodate the tool (10) in such a way that the cutting insert (14) is located in a desired position on the tool (10) and can be clamped in the desired position by actuating the clamping device (30). A method for fastening at least one cutting insert (14) to the parent body (12) includes fitting the parent body (12) with the cutting insert (14); arranging the parent body (12) in a jig (32); bringing the cutting insert (14) into a desired position; and clamping the cutting insert (14) in the desired position.

A hydraulic coupling system includes an adapter, a shell mill, a threaded member, and a chucking membrane. The adapter includes a tapered pilot disposed on and extending from an end face. The shell mill includes a central counter bore for enabling the pilot of the adapter to be inserted therein. The threaded member includes at least one sealing member and is capable of being threaded into a threaded bore of the shell mill. The chucking membrane includes an intermediate portion disposed between two flanges and forms a fluid-tight channel for hydraulic fluid. The chucking member has a tapered inside surface. When the threaded member is threaded into the shell mill, the tapered surfaces of the pilot and the chucking membrane cause an axial force to seat the end face of the shell mill firmly against the end face of the adapter.

A power assisted drill press having a feed cylinder fed by a variable pressure regulator which allows a user to controllably feed a bit and work material together while activating a drill motor to rotate the bit. An embodiment of the power assisted drill press utilizes a suction cup and venturi system for attachment of the press to a surface work material. The drill press uniquely allows a person to variably activate the feed cylinder and also activate the drill motor with a single hand.

An arrangement forms control windows (5) in a cylinder wall (2) of a cylinder housing (1) for a two-stroke internal combustion engine as openings of flow channels (4) in the interior space (3) of the cylinder delimited by the cylinder wall (2). The arrangement includes a driveable tool (7) which can be introduced at a free end (16) of a rotatable tool holder (17) into the interior space (3). The tool (7) can be brought into engagement with the cylinder wall (2) in the position in which the control window (5) is to be formed by transverse movement (13) with reference to a rotational axis (11) of the tool holder (17). A milling tool having a drive axis (19) is provided which lies essentially orthogonally to the rotational axis (11) of the tool holder (17) in order to provide a rapid and cost effective manufacture of a cylinder housing (1) with a precise manufacture of the control windows (5) in the cylinder wall (2).

Material removal tool (310) with a translating bar (360) having an actuation surface (362) shaped as a cone or frustum, wherein an axial position of the cone or frustum along a length of the translating bar (360) corresponds to a position of a push rod (364) in operable contact with flexibly mounted cartridges (312) on which cutting inserts (316) are mounted is disclosed. The translating bar (360) is actuated between a first and second position to place different combinations of cutting inserts (316) from different cutting positions (a-d) in a radially outermost position. Various combinations of cutting positions (a-d) and cutting inserts (316) are disclosed along with various methods for removing material using the disclosed material removal tool (310).
