An insert for milling applications in which a radial rake face includes a concave conical portion defined to achieve constant positive radial rake throughout the length of a radial cutting edge at the angle of inclination thereof as the insert is intended to be mounted in a cutter body. The insert includes an axial rake face having a sloping portion defined to achieve positive axial rake as the insert is intended to be mounted in a cutter body. The upper surface of the insert includes planar regions and bend surfaces merging smoothly with the radial rake faces and axial rake faces to assist in chip expulsion during cutting.

Cutting insert and cutter for milling

A holder blade is provided which includes an elongated member including an insert cavity for securing an insert in place. The insert cavity includes opposing surfaces which include V-shaped lengths which engage corresponding V-shaped lengths provided in opposite surfaces of the insert. A camming action is provided so that the opposing surfaces of the insert cavity may tightly grip the insert.

Holder blade

A rotary slotting tool that includes a circular tool body having a V-shaped groove in its peripheral edge to establish a centering plane for individual cutter element holders. A pocket is formed in the leading face of each holder for mounting an individual cutter element. The pocket structure configuration is varied between successive holders so that successive cutter elements overhang different side faces of the associated holders. A common cutter element configuration is used for all of the cutter elements.

Rotary slotting tool having staggered cutting elements

A center cutting end mill incorporating indexable inserts with positive axial rake angles. Multisegmented rake faces provide support for positive rake cutting edges enabling an improved feed rate.

Center and peripheral cutting end mill

A disposable indexable cutting insert having opposed irregularly curved cutting edges and a smooth continuous transition along each cutting edge and a corresponding radiused corner edge.

Cutting insert

Coarse radially adjustable tool holder employing eccentric adjustment ring combined with linear guide means confining tool point to linear adjustment path within fine adjustment eccentric bushing such as provided by 'Briney Precision Adjustment Tool'.
