Abstract: A rotary power tool is provided having a remotely actuated chuck device. The chuck is mounted onto the end of a drive spindle that extends from the casing of the power tool. The chuck includes an outer sleeve member that is axially movable relative to a drive spindle between a gripping and release position. A sleeve actuating device is provided having a first member engaged with the outer sleeve member and which extends generally radially outward from the drive spindle or chuck. The first member is movable in a direction so as to move the outer sleeve member between the gripping position and release position. The sleeve actuating device includes an actuator member configured with the first member to move the first member upon an external force being applied thereto. A base is rotatably advanceable and concentric on the casing. A helical opening is formed in the base. The chuck actuating device fits into the helical groove so that the base is fully rotatably adjustable without interference from the actuating device.

Abstract: A bit attaching arrangement for a power tool includes a bit locking member rotatable with respect to the output shaft of the power tool. A first gear is fixed to the bit locking member so that rotation of the first gear causes rotation of the locking member. A second gear is fixed to the output shaft so that rotation of the second gear causes rotation of the output shaft. A third gear engages both said first and second gear simultaneously and is capable of rotation by an operator of the power tool. Rotation of the third gear results in counter rotation between the bit locking member and the output shaft so as to result in securement of the bit to the shaft. A further aspect of the invention includes a pinion shaft onto which the third gear is mounted. The pinion shaft is slidably mounted to the power tool so that the third gear may be moved between a position where it engages both the first and second gears and can be used to tighten the bit in place, and a second position wherein it does not engage either of the gears and allows operation of the power tool.

Abstract: A rotary power tool, such as a router, includes an actuating device engaged with a chuck device to move the chuck device between its gripping and release positions. The actuating device includes a lever member that extends axially relative to a casing of the power tool within an inner circumference of a base member. This lever member is movable relative to the casing and is engaged with the chuck so that movement of the lever is imparted to the chuck device causing the chuck device to move axially between its gripping and release positions.

Abstract: A tool holder includes a body with a central internal threaded section, and a coolant coupling device within the tool holder. The coolant coupling device includes a threaded body section to engage the internal threads of the tool holder, a smaller diameter nose section, and a coolant passage through the device to align with a coolant passage in a cutting tool. A sealing ring around the end of the coolant passage forms a seal when the coolant coupling device abuts against a tool shank. The body section includes a wrench slot by which to turn the device for axial movement within the tool holder.

Abstract: A tool holder has a main sleeve to be attached to a tapered bore of a spindle of a machine tool, and a subholder which is coupled with the main sleeve and to which a tool is attached. The tapered shank of the main sleeve is inserted into the tapered bore of the spindle having a taper of 7/24. The main sleeve has a tapered hole having a taper of 1/10. A tapered sleeve which is elastically deformable in the radial direction is fitted onto the outer circumference surface of a shank portion of a subholder body of the subholder. The subholder is coupled with the main sleeve such that the outer circumferential surface of the tapered sleeve having a taper of 1/10 intimately contacts the circumferential surface of the tapered hole and the rear end surface of a flange of the subholder body intimately contacts the forward end surface of the main sleeve. This structure prevents the generation of vibrations during machining. Also, the tool holder makes it possible to efficiently machine a workpiece at high speed, and to increase the durability of the tool and the spindle.

Abstract: A collet chuck having a tubular housing with the inside diameter tapering outwardly at one end to match the taper of an inserted collet, threads on the reduced outside diameter of the housing at this same end for a collet closer or disc tightener to screw on. This collect closer is in the shape of a disc with knurled outer surface, and radial holes spaced in this outer surface so a lever can be inserted in any of these holes to assist in screwing the disc on the housing. A section of the inside diameter of the disc is threaded, the remaining part is an enlarged recess. When the disc is screwed on the housing, a needle thrust bearing and the flat ring of a rod assembly is loosely positioned in the recess of the disc tightener. A lock ring that slides on the larger diameter of the housing is fastened to the disc tightener to form a closed pocket with the ring and bearing inside. Rods fastened to the flat ring and sliding in axial holes through the wall section of the larger diameter of the housing, have a flange nut fastened to the rod ends protruding from the housing. This flange nut slides in the enlarged diameter end of the housing and has an internal threaded diameter for the collet to screw into. With the collet in place, any movement of the disc tightener will transfer to the collet, causing the collet to move in and out of the housing. Thus the collet can clamp or release a workpiece. A threaded plunger screwed through an axial hole in the wall of the housing, has a spring actuated tip to fit in the groove of the collet to prevent the collet from rotating, but to allow it to slide in and out of the housing.

Abstract: The self-centering collet makes it possible to obtain a very high precision which makes it possible to grip, for example, bits with a diameter less than 0.3 mm with extremely small tolerances thanks to two arrangements: the first, by depressing in the middle zone (BC) the outside conical surface (AD) of the central body of collet (1) or of collet-holder (7) so that, with the collet closed, the two complementary surfaces touch one another only in their end parts (AB and CD); the second, in making ring nut (6) press on head (1") of central body (1) of the collet only along a circular rim (G) located near axis (EF).
