摘要： A tip-changeable rotary cutting tool in which a tip having axis-symmetrically arranged cutting edges is inserted into a groove that cuts across the center of the holder's front end is improved in machining precision, product precision, and machining performance. Forward-facing oblique locking faces 8 are provided axis-symmetrically at the front ends of jaws 3 of a holder 1. The locking faces 8 cross each other at a position a certain distance (one-third to two-thirds the width of the tip) away from the front end of the tool to lock backward-facing engaging faces 9 provided at some longitudinal midpoint position of a tip 5. The shortened distance between the cutting edge 6 and the locking position suppresses the runout deviation of the tip, decreasing the displacements of the cutting edges due to the runout deviation. A large chip pocket can also be provided.

摘要： A diamond coated drill capable of drilling large holes in composite materials and then reaming the holes to their correct size includes a pair of prongs extending from a shank. Each of the prongs has a tip, a grinder, and a reamer. The tips initiate a hole, the grinders gradually grind the hole to the proper size, and the reamers control the final diameter of the hole. The tips have a coarse grit diamond coating. The grinders also have a coarse grit diamond coating and are axially tapered toward the tips. The reamers have a fine grit diamond coating and are disposed axially above the grinders and the shank of the drill. The grinders apply a radial load to the composite material resulting in no fiber breakout or splintering. The composite material drilled by the drill naturally falls out of the drill during drilling.

摘要： A core drill extender apparatus comprises an extender tube that is adapted to make a screw connection to a driver, and a connector assembly releasably mounted in the front end of the tube for connecting the extender tube to a core drill. The connector assembly comprises a tapered mandrel having a threaded axial extension at its front end for making a screw connection to a core drill, and an expandable locking sleeve that surrounds and engages the outer surface of the mandrel. The sleeve is made so that moving it relative to the mandrel in the direction of increasing mandrel outer surface diameter will cause the sleeve to expand radially and into tight frictional engagement with the extender tube.

摘要： A composite rotary tool includes at least first and second regions comprising first and second materials, respectively. The first and second regions are autogenously bonded and differ with respect to at least one characteristic such as, for example, modulus of elasticity, hardness, wear resistance, fracture toughness, tensile strength, corrosion resistance, coefficient of thermal expansion, or coefficient of thermal conductivity. A method for producing the composite rotary tool includes placing a first metallurgical powder into a first region of a void of a mold, and placing a second metallurgical powder into a second region of the void. The first metallurgical powder differs from the second metallurgical powder, and at least a portion of the first metallurgical is brought into contact with the second metallurgical powder. The mold is compressed to consolidate the first and second metallurgical powders to form a compact, and the compact subsequently is sintered.

摘要： A tool holder, which has a tool bit pivotal in a recess in one end thereof, extends coaxially through a generally bell shaped piston housing, and through the center of a piston slidably mounted on the holder for limited reciprocation in the housing axially thereof. The piston is urged by a compressing spring to a retracted position against one end of the housing, and has a reduced diameter annular wall that projects coaxially toward the end of the holder containing the tool bit. A tool actuating rod, which is pivotal in an axial bore in the holder, has on one end a lever which extends slidably into an axially extending helical slot formed in the annular piston wall, and is connected at its opposite end to the tool bit. When the piston is in its retracted position, the helical slot in its annular wall causes the actuating rod to swing the tool bit to an inoperative position within the holder recess. In use the end of the holder opposite the tool bit is connected to the drive spindle of a machine tool and a supply of air or fluid under pressure which passes through an axial bore and radial port in the holder to one side of the retracted piston causing the piston to advance it helical slot relative to the actuating rod lever thereby to pivot the tool bit out of the recess and into an operative position.
