Abstract: An indexable parting blade has opposite blade first and second sides, a blade peripheral edge, a central index axis, and at least first, second and third insert pockets located along the blade peripheral edge. The parting blade also has first, second and third coolant channels, each forming a coolant path from a corresponding inlet to a corresponding one of the insert pockets. Each coolant channel includes a rake outlet opening out to a rake side of its corresponding insert pocket and a relief outlet opening out to a relief side of that same insert pocket. The inlet corresponding to a given coolant channel is located further from that coolant channel's insert pocket than at least one of (a) the inlet corresponding to a different coolant channel, and (b) the central index axis.

Abstract: A slotting tool body includes a disc-like cutter portion and a shank portion projecting rearwardly therefrom. The cutter portion includes a resilient clamping portion having a peripherally disposed insert receiving slot. The shank portion includes a peripherally disposed forward shank recess that is axially adjacent the cutter portion. A radially inward portion of the insert receiving slot merges in the rearward direction with the forward shank recess. A cutting insert is releasably and resiliently clamped in the insert receiving slot to form a rotary slot cutting tool. The cutting insert includes two cutting portions that each include a long and short insert lateral extension, the long insert lateral extension being longer than the short insert lateral extension. The longest insert lateral extensions are orated on opposite sides of the cutting insert.

Abstract: A cutting tool includes a cutting insert resiliently clamped in an insert holder. The insert holder has a holder longitudinal axis defining opposite forward to rearward directions, and a transversely oriented insert receiving pocket having a pocket longitudinal axis and a pocket front opening. The insert holder includes a forwardly located insert mounting portion that includes upper and lower jaws which together define the insert receiving pocket. The insert receiving pocket at the lower jaw includes a pocket lower clamping surface. The insert receiving pocket at the upper jaw includes a pocket upper clamping surface which faces mutually towards the pocket lower clamping surface. The insert receiving pocket at one of the upper and lower jaws includes a pocket stopper surface facing generally towards the pocket front opening. The upper jaw includes an outer flexibility groove recessed in the holder peripheral surface.

Abstract: A cutting head rotatable about a first axis, comprising an intermediate portion and a tip portion. The intermediate portion has a plurality of leading edges defining a cutting diameter, and the tip portion has an axially forwardmost tip point and a plurality of front surfaces with outer and inner cutting edges. An outer rake surface adjacent to each outer cutting edge has a positive outer rake angle, and an inner rake surface adjacent to each inner cutting edge has a negative inner rake angle. Each outer rake surface is disposed on a head flute intersecting one of the leading edges, and each inner rake surface is disposed on a gash intersecting one of the head flutes. Each gash extends to a gash path end point located a first distance axially rearward of the tip point, and the first distance is greater than thirty percent of the cutting diameter.

Abstract: A rotary cutting tool includes a cutting head and a tool shank, each having an axial abutment surface and a plurality of drive surfaces. One of the two includes a locating pin, while the other includes a pin receptacle and at least one clamping through bore that opens out to the pin receptacle. The locating pin is received into the pin receptacle. The cutting head and tool shank are releasably clamped together by at least one clamping member that passes through the at least one clamping through bore and acts on the locating pin so that the drive surfaces and the axial abutment surfaces on each part abut each other.
