Abstract: An expandable reamer includes a shank portion, a cutting portion extending from the shank portion, and a tapered pin capable of being at least partially received in the cutting portion. The cutting portion includes a plurality of blades separated by flutes, and a tapered inner surface with threads. The tapered pin includes a tapered outer surface with threads and causes expansion or contraction of the cutting portion when the tapered pin is screwed or unscrewed into the cutting portion. In one embodiment, a coolant channel extends from a coolant cavity through a wall of the cutting portion to provide fluid to the blades during machining of through-holes. In another embodiment, the tapered pin includes a coolant passage in fluid communication with the coolant cavity to provide fluid to the blades during machining of blind holes.

Abstract: This application relates to a twist drill for use in a machine tool with a major cutting edge divided into two partial cutting edges by a chisel edge wherein longitudinal cutting edges extend along the length of the drill such that the first longitudinal cutting edge makes a rough cut and the second longitudinal cutting edge makes a finishing cut during operation.

Abstract: The invention relates to a cutting insert, in particular for a milling work, with a basic body which respectively has on opposite sides peripheral cutting edges, which protrude beyond the respectively adjoining face regions (15), descending at a positive rake angle, in the middle of which one or more planar supporting surfaces (16) are arranged, and with a central fastening hole (12) for receiving a tensioning screw. Arranged around the central fastening hole is at least one conical surface (19), with a cone descending inwards, i.e. towards the fastening hole.

Abstract: A milling cutter for machining work pieces, which comprises at least one cutting insert that can be adjusted by an adjusting element. The adjusting element is a one-piece element having an adjusting cone that extends between a screw head and a threaded shank. The adjusting cone engages with a recess provided in a lateral face of the cutting insert, which recess may also have a conical shape which substantially corresponds to the conical shape of the adjusting cone.

Abstract: A metal cutting system with a tool holder, a shim, an insert with a top depression, a top piece and a clamp. A rake face cooling channel for fluid delivery is formed between the top piece and the depression in the insert. A primary discharge slot at the end of the rake face cooling channel delivers fluid from below the cutting edge of the insert. A second cooling channel for delivery of fluid to the flank face is formed between the insert and the shim or is formed between the shim and the tool holder with a portion of the cooling channel passing through the shim.

Abstract: A tool holder assembly that includes a tool holder member adapted to be secured to a machine tool and a cutting insert support/clamp for clamping and supporting a cutting insert. The support/clamp member includes a plurality of serrations that are engageable with complementally formed serrations on the tool holder whereby a tight fitting engagement is achieved using removable fasteners. The support/clamp includes a clamping arm elastically movable towards and away from a support base and a clamping block connected to the connecting arm adapted to receive clamping forces from a threaded clamping bolt. The clamping bolt defines a force applying surface located in a first plane whereas the clamping block defines a force receiving surface located in a second plane, the first and second planes located at a diverging angle with respect to each other. The clamping block includes an edge portion engageable with a step on the tool holder that is spaced from the clamping arm.

Abstract: A cutting insert for use in chipforming and material removal from a workpiece wherein coolant is supplied to the cutting insert from a coolant source. The cutting insert includes at least one discrete cutting location and at least one distinct internal channel that corresponds to the cutting location. The internal channel has an inlet to receive coolant and an outlet to exit coolant. The outlet is proximate to the cutting location, and the inlet is radial inward of the outlet.

Abstract: A method for making by assembling a tool to and in a tool holder, and the tool and tool holder, and the assembled tool and tool holder. The tool is shrink-fitted into a cylindrical bore of the tool holder, and a shoulder of the tool abuts an abutment face of the tool holder. Structure, such as press, a screw, a draw bolt, or a cylinder, for example, is provided to apply an axial force to the cutting tool to force the tool shoulder against the abutment face of the tool holder.

Abstract: The invention relates to a tool coupling for connecting a tool carrier which can be driven in a rotating manner, in particular a milling tool with a machine spindle or an adapter connected to a spindle, wherein four drivers in a crosswise formation are provided for transmitting torque between the said parts and in the clamping state engage in four recesses. To allow the tool coupling to be easily operated and to be of a simple construction, and also to counteract undesired jamming, it is proposed that the drivers respectively have on the side transmitting the torque a planar face which lies with full surface-area contact against a wall of a groove-shaped recess in the clamping state, that on the opposite side the driver has a smaller positively or frictionally engaging contact with the wall there of the groove-shaped recess and that a quick-acting clamping device is providing for the axial clamping of the tool carrier and the spindle or an adapter.

Abstract: The invention relates to a milling cutter head having a number of blade supports (11) which are inserted in recesses of a base body (10) and have blades (12), wherein each blade support can be axially displaced by a wedge and fixed in the milling cutter head by clamping elements. According to the invention, the blade supports each have a shank which is arranged in a receiving bore of the base body and can be fixed via a centrally (13) located clamping piece (18).
