摘要： A sawblade apparatus includes a sawblade and an arbor. The arbor which is adapted to have the sawblade mounted thereon possesses a plurality of outer drive surfaces circumferentially spaced about the outer periphery of the arbor. The sawblade is provided with a centrally located mounting hole that is bounded by a plurality of inner driven surfaces circumferentially spaced about the mounting hole for operatively engaging the outer drive surfaces on the arbor when the arbor is rotatably driven so that rotation of the arbor results in rotation of the sawblade in a rotational direction. The inner driven surfaces operatively engage the outer drive surfaces at respective interfaces to produce an interface force during operation of the sawing apparatus. The mounting hole in the sawblade has an inner diameter that is greater than the outer diameter of the arbor so that during a cutting operation the outer peripheral surface of the arbor is spaced from the inner peripheral surface of the mounting hole in the sawblade. The drive surfaces and the driven surfaces are configured to produce a radially inwardly directed radial component of the interface force at the interfaces during operation of the sawing apparatus.
