A tool system including a liner having a body and a plurality of coupling members extending from the body, the body includes a first aperture through which at least part of a tool extends and is configured for coupling to a tool fixture, and a housing having an second aperture through which the at least part of the tool extends, a first end of the housing having grooves configured to mate with the plurality of coupling members to couple the tool within the grooves and to the tool fixture.

A treatment assembly for securing a treatment member to a shaft that includes the treatment member and a female attachment member. The treatment member defines a longitudinal axis, and has a distal end and a proximal end. The proximal end includes an attachment recess defined therein. The female attachment member has a distal end, a proximal end, and a shaft recess defined in the proximal end. The female attachment member is secured in the attachment recess of the treatment member. The shaft recess is defined by an interior surface that includes a first flat surface. The interior surface includes a first detent defined therein. When the shaft is received in the shaft recess, the first flat surface is operatively engaged with a first opposing flat surface on a male attachment member and a first ball is biased into the first detent.

A tool holder has a main body and a holding pin onto which a rotary tool having a corresponding holding bore can be placed. At least one channel for transporting coolant or lubricant, the channel leading to the outer circumference of the holding pin, is arranged in the tool holder. In order to enable cooling of the cutting edges of the rotary tool without great production complexity, at least one longitudinal groove for conducting the coolant or lubricant in a longitudinal direction of the holding pin is arranged on the outer circumference of the holding pin.

The holder for a head replacement-type cutting tool is provided with a holder main body and a tubular coupling member 3 which is housed in an attachment hole formed on the holder main body and made of a metal material lower in hardness than the holder main body. A recessed part is formed on an inner circumferential face of the attachment hole, the coupling member is engaged with the recessed part by firmly attaching the outer circumferential face thereof on the inner circumferential face of the attachment hole, and the coupling member is provided with an attachment screw part which is screwed into a head-side screw part formed at the replacement-type cutting head.

A cutter holder has a body and a damping assembly. The damping assembly is contained inside the body. The damping assembly has a central damping pole and six auxiliary damping poles. The six auxiliary damping poles are arranged around the central damping pole. The body has a specific weight. The central damping pole has a specific weight larger than the specific weight of the body. Each one of the six auxiliary damping poles has a specific weight larger than the specific weight of the body. The damping assembly is utilized to reduce vibrations caused by machining.

A rotary cutting tool includes a replaceable cutting head and a tool holder. The replaceable cutting head includes a forward cutting portion and a rearward mounting portion. The mounting portion includes a male coupling member that includes a straight external thread. The tool holder includes a female coupling member that includes a conical internal thread. When the rotary cutting tool is in a locked position, the external thread is threadingly engaged with the internal thread.

An assembly for tightening and securing includes a first male part and a second female part fitted together, which have complementary forms. The fitting includes at least one contact surface of the first part with the second part. The assembly also includes at least one annular means mounted on the periphery of one of the two parts. The annular means is connected in a translational manner to the part on which the annular means is mounted when the annular means abuts with the part on which the means is mounted, and arranged to interact with a peripheral surface of the complementary part during a rotation of the annular means in relation to the complementary part.
