Cutting tool holders are disclosed that include vibration dampening elements. The vibration dampening elements may extend parallel to a longitudinal plane of the cutting tool holder. The vibration dampening elements allow the cutting tool holders to have a smaller width while still providing higher grooving depth.

A cylindrical cutting system, a bit holder assembly, and machine for milling or scarifying road surfaces are disclosed. A bit holder is attachable to a milling platform, and includes an inward facing surface for engaging a corresponding mating surface of the milling platform. The inward facing surface of the bit holder and the mating surface include aligning fastener and pin openings. A fastener and a pin are inserted within the respective openings to couple the bit holder to the milling platform. The mating surface may define a part of a recess formed in the milling platform. A wear element may be disposed at the leading side of the bit holder. Multiple platforms may be coupled together with axially extended platform fasteners.

A cutting system for removing an excess material along a length of a channel constructed using an additive manufacturing process is disclosed. In various embodiments, the cutting system includes a cutter head; a cutter blade attached to the cutter head; a drive cable configured to rotate the cutter head; and a cutter base attached to the cutter head and having a cutter base outer surface configured to contact an internal surface within the channel to guide the cutter blade against the excess material.

A cutting tool assembly includes a parting blade and a blade holder for holding same. The cutting tool assembly is configured for conveying pressurized coolant via the holder to a cutting portion of the parting blade. The blade holder includes a deceleration chamber configured for reducing the impact of the pressurized coolant against the parting blade.

A grooving blade for chip removing machining includes a cutting insert pocket and a damping arrangement fixed to the blade. The damping arrangement projects laterally with respect to at least one major surface of the blade. A grooving tool and a method of grooving a metallic workpiece are also disclosed.

Provided is a cutting tool for back turning capable of improving chipping resistance. A cutting tool wherein a wall surface of a chip breaker includes a first wall surface that is formed along a first ridgeline, and a reinforcing surface that is connected to the first wall surface and a first end surface at an end portion of the chip breaker on the side of a first cutting edge, and that forms an angle of 90 degrees or an obtuse angle with the first end surface.
