摘要： A holesaw system (10) comprises a holesaw (20) including a base (22) and a generally cylindrical wall (24) with a proximal end coupled to the base and a distal end with a cutting edge (26); a pilot drill bit (30) including a front cutting tip (36), a rear shank portion (32), and an intermediate portion (34) between the front cutting tip and the rear shank portion; and an arbor (40) coupleable to the holesaw and to the pilot drill bit. The arbor is configured to be operable in a first mode in which the holesaw and the pilot drill bit are rotatable in unison to form a hole in a workpiece and in a second mode in which the pilot drill bit is rotatable independently of the holesaw to remove a plug of material from the holesaw.

摘要： A circular saw blade (10) includes a circular plate-like body (12) having a first side face (14), an opposite second side face (16), a periphery (18), and a central opening (20) defining a center point (21), and rotatable in a cutting direction (C). A plurality of circumferentially-spaced teeth (22) are separated by a plurality of gullets (24). Each tooth has a rake face (30), a top face (32), a cutting edge at a junction between the rake face and the relief face, a first lateral face (36) joined to the top face at a first top edge (38), and a second lateral face (40) opposite the first lateral face and joined to the top face at a second top edge (42). The teeth include a plurality of first beveled teeth (22A), each with its top face (32A) beveled radially inward from its first top edge (38A) to its second top edge (42A), a plurality of second beveled teeth (22B), each with its top face (32B) beveled radially inward from its second top edge to its first top edge, and a plurality of unbeveled raker teeth (22C). The first beveled teeth, the second beveled teeth, and the unbeveled raker teeth are arranged in an alternating top bevel + raker (ATB+R) pattern. The second top edge (42B) of the second beveled tooth (22B) is disposed radially inward toward the central opening from the first top edge (38A) of the first beveled tooth (22A) by a first drop distance (d1).

摘要： A reciprocating saw blade (100) is provided including a blade cutting edge (108) including a plurality of teeth (122) and a plurality of gullets (124). At least a portion of the plurality of teeth (122) each includes a rake face (450), a relief face (460), a tooth cutting edge (A), and at least one non-cutting tooth edge (B) extending on a first side face (470) transverse to the rake face (450) and the relief face (460), and a second side face (475) opposite the first side face (470) and transverse to the rake face (450) and the relief face (460), a first relief-side edge (C) at a junction between the first side face (470) and the relief face (460), and a second relief-side edge (C) at a junction between the second side face (475) and the relief face (460). At least one of the first and second relief-side edges (C) includes a modified portion (790) extending rearward from the rake face (450).

摘要： An accessory (100) for an oscillating power tool (12) includes an attachment portion (104) configured to be coupled to an oscillating power tool and a working portion (102) extending generally along a longitudinal axis (X). The working portion (102) has a rear end portion (120) coupled to the attachment portion (104), a front cutting edge (122) opposite the rear end portion (120), a first side edge (124) extending from the front cutting edge (122) to the rear end portion (120), and a second side edge (126) opposite the first side edge (124) and extending from the front cutting edge (122) to the rear end portion (120). The working portion (102) includes an at least partially curved surface that contains the longitudinal axis (X). At least a portion of the first side edge (124) includes a first side cutting edge portion (132).

摘要： A circular saw blade includes a plurality of cutting teeth repeatedly alternating between a first set of cutting teeth and a second set of cutting teeth around the periphery of the saw blade. Each first set of cutting teeth includes at least two efficient cutting teeth, each second set of cutting teeth comprising at least one robust cutting tooth. Each first set of teeth and each second set of teeth are configured such that, if one tooth in the first set of teeth breaks, the chip load in the immediately following second set of teeth increases by less than approximately 45%.
