An upper surface of a cutting insert includes a first rake face and a second seating surface. A lower surface of the cutting insert includes a second rake face and a first seating surface. The cutting edge includes a first cutting edge portion formed at a crossing edge line portion between the first rake face and a flank face and a second cutting edge portion formed at a crossing edge line portion between the second rake face and the flank face. The first cutting edge portion and the crossing edge line portion between the first seating surface and the flank face are positioned opposite each other. The second cutting edge portion and the crossing edge line portion between the second seating surface and the flank face are positioned opposite each other.

The present invention is directed to a cutting tool, comprising: at least one cutting insert; a tool body including a pocket portion to which the cutting insert is mounted; a means for fixing the cutting insert to the pocket portion of the tool body; and a screw for finely adjusting the position of the cutting insert fixed to the pocket portion of the tool body. The screw has a head portion, a threaded portion and a portion for connecting the head portion to the threaded portion. The pocket portion has a bottom surface with a screw hole formed thereon into which the threaded portion is fastened. It also has a side wall comprising a surface for closely contacting the head portion of the screw. The head portion of the screw closely contacts and resiliently pressurizes the close contact surface of the pocket portion when the threaded portion is fastened into the screw hole.

The present invention provides a cutting tooth for use on a brush cutter head. The cutting tooth includes a cutting portion having a first face and a second face. The first face and the second face cooperate to define a tapering profile terminating in a cutting edge. The first face of the cutting portion carries a plurality of ridges formed thereon to direct cutting debris away from the cutting edge and facilitate passage of the debris along the trailing face when the cutting tooth is in use.

A slotting cutter includes a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body. A plurality of cutting insert receiving pockets and a corresponding number of thread holes are formed about a perimeter of the body. A cutting insert is replaceably mounted in each insert receiving pocket of the cutter body, and a clamping screw is replaceably threaded in each thread hole of the cutter body. A cantilevered portion is disposed between each insert receiving pocket and a respective thread hole that exerts a downward force to securely hold the cutting insert in the cutter body when the clamping screw is threaded into the thread hole.

A circular cutting insert includes a top surface having a top edge portion, a side surface having a clearance surface and a clearance edge portion. A cutting edge is formed between the clearance edge portion and the top edge portion. The clearance edge portion and the top edge portion form a wedge angle. The wedge angle varies as a function of circumferential position about a central axis of the insert relative to a point on the cutting edge.

The invention relates to a tool for machining a workpiece, incorporating a holder having a locating opening arranged at the end face and a cutting head having at least one cutting element arranged on the workpiece-side end. Furthermore, the tool has a sleeve which is made substantially of carbide and which, with a first, holder-side end, is inserted in an accurately fitting manner into the locating opening of the holder, and the cutting head is arranged in or on the second, cutting-head-side end of said sleeve, and coupling means for coupling the holder, cutting head and sleeve.
摘要:
A cutting insert (14) is formed with an insert aperture (32) opening out to insert top and bottom surfaces (14A, 14B) of the cutting insert (14). In a plan view of the insert top surface (14A), the cutting insert (14) and the insert aperture (32) both have oblong shapes which are elongated along a common insert longitudinal axis (AIL). The aperture (32) includes first and second side surfaces (32A1, 32A2) which each extend along the insert longitudinal axis (AIL), and aperture first and second end surfaces (32B1, 32B2) which each extend transverse relative to the insert longitudinal axis (AIL). At least one of the aperture first and second end surfaces (32B1, 32B2) is formed with a clamping lip (32C1, 32C2).
