  • Patent number: 10987743
    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.

  • Patent number: 10953474
    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.

  • Publication number: 20200108449
    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.

  • Patent number: 8992141
    Abstract: A cutting head has a resilient male coupling member. The cutting head has a central resilience slit that extends between two major surfaces and opens out to the male coupling member and at least one lateral resilience slit that extends between the two major surfaces and opens out to a base surface. The central resilience slit and the at least one lateral resilience slit each have forwardmost points, located forward of the base surface. Also, a cutting tool that has a tool holder with the cutting head secured thereto. The tool holder has an insert pocket that includes a forward facing holder base abutment surface that has a female coupling member.
