Abstract: A hole saw including a plurality of sidewall openings is provided. The sidewall openings are shaped and grouped in patterns that improve debris ejection of the hole saw and that allow for easy access to the interior of the hole saw for manual debris removal by the user. The opening groups are space from each other by larger uninterrupted areas such that the hole saw has a high strength despite the number and size of openings provided in the saw sidewall.

Abstract: A system is disclosed for releasable coupling of a hole saw to a drill arbor. The system includes an elongate drill arbor configured at a first end to be clamped in a drill chuck of a drill, and a hole saw adapter provided with a longitudinal bore in which the drill arbor can be received so that an inner surface of the longitudinal bore of the hole saw adapter is mounted slidably on an outer surface of the drill arbor in the longitudinal direction of the drill arbor. The drill arbor includes an actuator member and at least one retaining element co-acting therewith. The inner surface of the longitudinal bore of the hole saw adapter is provided with a recess into which the retaining element of the drill arbor can protrude.

Abstract: A hole cutter can include a cylindrical blade body with a cutting edge and one or more axially-elongated apertures. Each axially-elongated aperture can include a first fulcrum axially spaced from the cutting edge, and a second fulcrum axially spaced further away from the cutting edge than the first fulcrum. The blade body can also include a third fulcrum defined by a second aperture different from the one or more axially-elongated apertures. The third fulcrum may be spaced closer to the cutting than the first and second fulcrums. A lever, such as a screw driver, can be inserted into the apertures and placed against each of the fulcrums to lever slugs out of the interior of the blade body. The third fulcrum may alternatively be defined by another axially-elongated aperture that is located a different distance from the cutting edge than the axially-elongated aperture containing the first and second fulcrums.

Abstract: Systems, apparatus, and methods may be adapted for grafting tissue at a tissue site that may include an elongate housing and a plurality of elongate cutting members. The plurality of elongate cutting members may define a cutting surface at a distal end of the elongate housing. The cutting surface may be adapted to contract from a first diameter to a second diameter that is less than the first diameter. The contraction of the cutting surface from the first diameter to the second diameter may define a tapered profile between the first diameter and the second diameter suitable for obtaining a tapered graft.

Abstract: A separating Hole Saw with an off-center locking system is disclosed. The ability to rotate and release the top section, with its attached tapered pilot bit, from the circular saw blade allows for the ease of extraction of that pilot bit from the sawed material, while at the same time provides access to the top of that sawed material. This access offers easy removal of the material that remains within the cavity of the circular saw blade.

Abstract: A hole cutter has a substantially cylindrical blade body defining a blade body circumference, a cutting edge formed on one end of the blade body, and an axially-elongated slot formed through the substantially cylindrical blade body. The axially-elongated slot is configured to receive chips flowing from the cutting edge within the interior of the blade body and (i) into the slot, and/or (ii) through the slot, to prevent the collection of such chips within the interior of the blade body and/or at an interface between the blade body and work piece. The axially-elongated slot defines a first end adjacent to the cutting edge, a second end axially spaced further from the cutting edge, and a slot area. The hole cutter further defines a total slot area to blade body circumference ratio within the range of about 0.1 to about 0.3 depending on the size of the hole cutter.

Abstract: A hole saw having efficient slug removal preferably includes a saw cup, a shank portion and a pilot cutting device. A cutting surface is formed on an open end of the saw cup. The inside surface, outside surface and cutting surface of the saw cup are given a low friction treatment. A fluoropolymer resin coating is used for the low friction treatment. The friction treatment is applied by spraying thereof on the saw cup. The saw cup is then heated to a predetermined temperature for a set period of time. The low friction treatment is cured when the saw cup is used. The shank portion is attached to a closed end of the saw cup with any suitable fastening process. The shank portion preferably retains the pilot cutting device.
