Abstract: A plug ejecting hole saw includes a saw cup provided at a front annular edge wall thereof with a plurality of forward protruding angled cutting teeth, and having at a rear end thereof a circular base wall having therethrough a non-circular aperture concentric with the cup. An arbor holder removably attachable to a saw cup of a selected size includes a collar axially slidably holding therewithin a central body having a front nose piece which protrudes axially outward of the collar, the front nose piece having a transverse cross-sectional shape adapted to be inheritably received into the saw cup aperture. The nose piece has formed in longitudinal wall surfaces thereof a pair of diametrically opposed, longitudinally disposed grooves, each of which longitudinally slidably holds therewithin a locking tab member urged forward to abut a separate one of a pair of diametrically opposed, front transversely disposed web ribs formed in the nose piece axially inward of the front transverse face of the nose piece. Each longitudinal groove communicates on one longitudinal side thereof with a separate one of a pair of transversely disposed grooves blocked by a forward biased tab member. When the nose piece is inserted into a saw cup aperture and pushed axially forward, each tab member is pushed rearward in a longitudinal groove, unblocking the transverse grooves and thereby allowing the nose piece to be rotated relative to the saw cup, with peripheral edge walls of the aperture received in the transverse grooves. With sufficient relative rotation, the front tab members become axially aligned with diametrically opposed larger diameter portions of the saw cup aperture, allowing each tab to be urged forward by a front spring to a location blocking a transverse groove and thereby preventing the arbor holder from becoming disengaged from the saw cup. The arbor holder has a coaxial bore provided with lefthand internal threads for threadably receiving an arbor having lefthand external threads, has a rear shank portion adapted to be clamped in a chuck of a power drill, and has a font collet flange for dampingly receiving the shank of a pilot drill. The hole saw includes a pilot drill held in the collet flange. Rotating the saw in a clockwise sense to cut a hole in a workpiece forms a plug lodged within the saw cup, while reversing the drill with the saw cup cocked in the workpiece hole causes the arbor to threadingly advance forward from the base of the saw cup, thus causing the collet flange to advance and push the plug from the saw cup.

Abstract: A device for removing embedded or broken fastening implements from bone, comprises a cylindrical drill bit with a cavity extending internally from a distal end of the bit. The distal end further defines a cutting surface disposed about the opening to the cavity. The interior surface of the cavity defines has a decreasing diameter as one proceeds away from the opening in the distal end, and thus the cutting surface is formed where the radial thickness of the wall of the drill bit is the thinnest. The interior surface of the cavity is susceptible to a galling effect when frictionally engaged by the exterior surface of the fastening implement intended to be removed. The operator places the drill bit around the site of the bone containing the fastening implement to be removed and rotates the bit so as to cut into the bone around the exterior surface of the fastening implement. Galling between the interior surface of the cavity and the exterior surface of the fastening implement causes the implement to adhere to the interior surface of the cavity of the drill bit. The operator then can move the drill bit away from the bone and remove the adhered fastening implement, which then can be discarded with the drill bit.

Abstract: A hole cutter (10) suitable for quickly cutting relatively large holes through wood, fiberboard, drywall and similar nonmetallic construction materials has a tubular member (16) attached to a back plate (14). The back plate includes attaching holes (22, 24) for attachment to a conventional hole saw arbor (12). The tubular member includes a gullet (28) which has a cutting bit (34) mounted adjacent thereto and facing in a direction of rotation. The cutting bit quickly cuts through wood and other materials. Chips generated during cutting are rapidly discharged away from the cutting edge (36) of the cutting bit and may pass through the gullet. Once the hole cutter has cut through, a core, which is cut out using the tool, is rapidly removed from the interior area (40). This is accomplished by using a screw driver or other tool extending through the gullet and prying out the core.

Abstract: A hollow crown drill has a set of cutting members (2, 3, 4) positioned on the leading or cutting end of an annular axially extending carrier member (1). The radial width of the cutting faces (2a, 3a, 4a) of the cutting members (2, 3, 4) increases opposite to the rotational direction (D) of the carrier member (1). In addition, the cutting members (3, 4) in the set disposed counter to the rotational direction (D) are offset in the direction parallel to the axis of the carrier member relative to the cutting member of the set leading in the rotational direction. This dimensional feature relates to the increase in the size of the cutting faces (2a, 3a, 4a). With the cutting faces (2a, 3a, 4a) dimensioned as above, each of the cutting members penetrates deep into the material being drilled, so that if the usual contact pressure forces are applied abrasive wear resulting in premature failure of the hollow crown drill does not occur.

Abstract: A tipped annular hole cutter is made by brazing all the cutting tips (30) simultaneously to the cylindrical wall (12) of the cutter body. The tips (30) have outer and inner lands (32, 34) which locate against the outer and inner surfaces (52, 54) of the cylindrical wall (12). This accurately locates the tips radially during brazing. The radially inner face (46) of the tip (30) is inclined so as to define an inner clearance face which has the necessary circumferential and radial clearances without therebeing any need to grind the inner face (46) after brazing.

Abstract: An annular hole cutter has a radially inner cutting tooth portion and a radially outer cutting tooth portion. Each of the inner and outer cutting tooth portions is formed with a flute for ejecting cut chips on the outer periphery of the cutter, and a cutting edge for radially outwardly pushing the cut chips. Therefore, the cut chips are smoothly ejected through the flute, and thus an annular hole is precisely cut at high speed.

Abstract: A metal cutting tool is disclosed which includes a cylindrical cutting body (12) having an outer cylindrical surface (13) approximating the size of the hole desired and an inner wall (14) which tapers towards a base (15). The cutter body further includes a notch (17) for removal of cutting chips which has a socket disposed on the leading edge thereof. A carbide cutting tip (26) is disposed in the socket with the cutting tip being substantially pyramidically shaped, having a blunt cutting edge (35) extending above the cutter body. The metal cutting tool further includes a pilot bit (36) extending axially through the center of the cutter body, with the pilot including a short fluted (37) section which extends above the top of the cutting tip and provides a pilot hole for guiding the cutting tip during hole cutting. The metal cutting tool is extremely durable and is particularly suited for use with a hand held drill, providing a minimum of resistance during cutting, reducing tip binding or breakage and thereby providing smooth holes in sheet metal at field locations.
