Abstract: A cutting tool holding mechanism for detachably holding a cutting tool includes: a collet chuck configured to clamp and unclamp the cutting tool; a piston disposed deeper on the proximal side of the spindle than the collet chuck and configured to urge the collet chuck by the pressure of a fluid supplied from the proximal side of the spindle in the direction from the proximal side toward the distal end side of the spindle so that the collet chuck unclamps the cutting tool; a spool valve provided in the piston and configured to open thanks to centrifugal force at the time when the spindle is turned, so as to supply the fluid fed from the spindle side to the cutting tool.

Abstract: An actuator for use with a power tool is disclosed. The power tool includes a spindle-chuck body defining a tool axis and a collet nut surrounding the tool axis and rotatable about the tool axis. The collet nut is coupled to the spindle-chuck body. The actuator comprises a holder positionable to engage the spindle-chuck body and an actuation assembly including a first member positioned to engage the collet nut when the holder engages the spindle-chuck body and a second member operatively coupled to the first member to rotate the first member about a first axis. The second member is rotatable about a second axis non-parallel to the first axis.

Abstract: An axially elongate dental machining portion includes a machining region machinable by a dental machining device, and a fixing region for fixing the axially elongate dental machining portion to a holder of the dental machining device. In the fixing region is a fixing projection oriented transversely relative to a longitudinal axis. In a condition of the machining portion being mounted in the holder, the fixing projection bears against a holding nose positioned in complementary relationship on the holder. The machining region has a machinable surface which has a maximum spacing relative to the longitudinal axis, measured normal to the longitudinal axis, and the fixing projection has a maximum spacing relative to the longitudinal axis, measured normal relative to the longitudinal axis, that is greater than the maximum spacing of the machinable surface relative to the longitudinal axis.

Abstract: A tool holding system for a rotary power tool is configured to clamp around a working tool when the working tool is inserted in the tool holding system. The tool holding system includes a sleeve having a frustroconical inner surface portion, a collet having frustoconical outer surface portion complementary to the inner surface portion, a spring mount operably connected to a motor for rotation by the motor, and a spring. The spring includes a first end portion operably connected to the collet to bias the collet toward a first position whereat the outer surface portion engages the inner surface portion, and a second end portion rotationally fixed with respect to the spring mount.

Abstract: A cutter holder has a body, a fastening bolt, and a vibration absorbing structure. The body has a specific weight. The fastening bolt is mounted inside the body. The vibration absorbing structure is mounted inside the body and has a sleeve, an elastic unit, a spacer, and a set nut. The sleeve is mounted around the fastening bolt and has a specific weight. The specific weight of the sleeve is larger than the specific weight of the body. The elastic unit is mounted around the fastening bolt and has two opposite ends. One of the ends of the elastic unit abuts against the sleeve. The spacer is mounted around the fastening bolt and abuts against the other end of the elastic unit. The set nut is screwed with the fastening bolt and abuts against the spacer.
