摘要： 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.

摘要： A cutting tool includes a hole saw, a pilot bit, and an arbor assembly. The assembly includes a shank having a first end and a second end. The first end of the shank is removably coupled to the hole saw and to the pilot bit, and the second end of the shank is configured to be coupled to a power tool. The assembly also includes a sleeve moveable along the shank and a first ball bearing disposed on the sleeve. The first ball bearing engages the hole saw to releasably secure the hole saw to the shank. The assembly includes a second ball bearing disposed on the shank. The second ball bearing engages the pilot bit to releasably secure the pilot bit to the shank. When the sleeve moves toward the second end of the shank, the first and second ball bearings disengage the hole saw and the pilot bit.

摘要： A hole cutter assembly is operable to cut a plurality of different sized diameter holes in a work piece. The hole cutter assembly includes an arbor configured to connect to a power tool for rotation about an axis, and a body coupled to the arbor for rotation with the arbor. The body defines an aperture. The hole cutter assembly includes a drill bit removably received in the aperture of the body for rotation with the arbor, an arm moveably coupled to the body, and a cutting blade coupled to the arm and moveable with the arm relative to the body. The arm is moveable relative to the body to adjust a cutting diameter of the hole cutter assembly when the drill bit is not received within the aperture. The arm is fixed relative to the body when the drill bit is received within the aperture.

摘要： A saw blade includes a cutting portion having consecutive first, second, and third cutting teeth. Each cutting tooth includes a rake surface, a relief surface, and a tip. The first cutting tooth includes a protrusion extending from the relief surface of the first cutting tooth. The cutting portion includes a first gullet positioned between the first cutting tooth and the second cutting tooth and a second gullet sized differently than the first gullet positioned between the second cutting tooth and the third cutting tooth. The cutting portion includes a first pitch extending over the first gullet from the tip of the first cutting tooth to the tip of the second cutting tooth. The cutting portion includes a second pitch different than the first pitch extending over the second gullet from the tip of the second cutting tooth to the tip of the third cutting tooth.

摘要： A drilling tool includes a step drill bit and an arbor assembly. The arbor assembly includes a shank having a first end, a second end opposite the first end, and a longitudinal axis extending through the first and second ends. The first end of the shank is removably coupled to the step drill bit, and the second end of the shank is configured to be coupled to a power tool. The arbor assembly includes a sleeve moveable along the shank parallel to the longitudinal axis, and a ball bearing disposed on the sleeve and moveable with the sleeve. The ball bearing engages the step drill bit to releasably secure the step drill bit to the shank. When the sleeve moves toward the second end of the shank, the ball bearing moves radially inward and disengages the step drill bit, allowing removal of the step drill bit from the shank.

摘要： A hole cutter assembly is operable to cut a plurality of different sized diameter holes in a work piece. The hole cutter assembly includes an arbor configured to connect to a power tool for rotation about an axis, a drill bit coupled to the arbor for rotation with the arbor, a first arm moveable relative to the axis, a first cutting blade coupled to the first arm and moveable with the first arm, a second arm moveable relative to the axis, and a second cutting blade coupled to the second arm and moveable with the second arm. The first and second cutting blades are selectively moveable relative to the axis to adjust a cutting diameter of the hole cutter assembly. The drill bit engages the first and second arms to inhibit movement of the first and second cutting blades relative to the drill bit.
