A forward grip system is disclosed for supporting a paintball gun. The forward grip system has an inner, longer, hollow cylindrical body with threaded sections with two conical ends with slits around them. The middle section of the inner, longer, hollow cylindrical body has a groove for the outer, shorter, hollow cylindrical body to rotate around on. The edges of the grooved middle section of the inner, longer, hollow cylindrical body are raised to secure the outer, shorter, hollow cylindrical body within the grooved middle section as it rotates around the inner, longer, hollow cylindrical body. A vertical shaft is connected onto the outer, shorter, hollow cylindrical body to function as the handle. There are two threaded locking collars for engaging each of the threaded sections of the inner, longer, hollow cylindrical body for the purpose of locking the forward grip system in place onto a paintball barrel.

A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.

A collet includes an axially rearward end and an axially forward end; a nose portion; a body portion having an outer surface and an inner surface for engaging a shank of a tool; a plurality of slots extending from the inner surface to the outer surface; and a plurality of coolant channels disposed within the collet between the plurality of longitudinally extending slots and extending entirely from the axially rearward end to the axially forward end of the collet. The slots include a first slot extending from the axial forward end to within an intermediary zone, a second slot extending from the axial rearward end to at least the tool holder engagement zone such that the second slot does not intersect the first slot, and a third slot from within the tool engagement zone to within the intermediary zone such that the third slot circumferentially overlaps the first and second slots.

A tool holder includes a basic body, in which a tool receiving region is located, a circular cylindrical clamping chuck having several joints and an external thread which has an external pitch angle, as well as a union nut having an internal thread which has an internal pitch angle. The union nut has a stopping face on the basic body or on the clamping chuck. The external pitch angle is different from the internal pitch angle.

A collet chuck with a chuck body, a collet, and a clamping nut in which the chuck body has a coupling section for coupling the collet chuck to the working spindle of a machine tool and has a collet holder embodied in the form of an inner cone and at least one thread groove for the screwing-on of the clamping nut; the collet has an outer cone, which is complementary to this inner cone, as well as a cylindrical tool holder; the collet chuck is embodied so that by tightening the clamping nut, the collet can be driven far enough into the collet holder that the tool shaft is held in a rotationally secured fashion; and the clamping nut has at least one thread groove; where rolling elements are inserted between the thread grooves of the chuck body and the clamping nut so that the clamping nut and the chuck body constitute a rolling element screw drive.

A chuck for use with a rotary power tool having an output spindle. The chuck includes a base and an inner sleeve threadedly coupled to the base. The inner sleeve has a central aperture. A collet is disposed within the central aperture of the inner sleeve and configured to be engaged by a portion of the inner sleeve to be tightened or untightened. The chuck further includes an outer sleeve surrounding the inner sleeve, and a detent member disposed between the inner sleeve and the outer sleeve. The detent member is coupled for co-rotation with the outer sleeve and configured to selectively transmit torque from the outer sleeve to the inner sleeve. When the collet is tightened, rotation of the outer sleeve causes axial displacement of the detent member relative to the inner sleeve as the outer sleeve and the detent member rotate relative to the inner sleeve.
