An arbor bit drives the drill nail on a saw blade. It may be attached or detachable while in other hole saws
, you must purchase the arbor as a separate component. The design of the attached arbor is such you cannot remove it. This aspect saves you from having to dismantle the saw each time you want to use a saw of a different size.Detachable arbor bits, on the other hand, are removable to pave the way for different saw blades. Two sizes of arbor bits exist, large and small. The shank size of the large arbor is 8.75mm inches thick, while the small arbor has a shank thickness of 11.1mm. A shank is that shaft where you attach the drill bit. To avoid swapping your arbor, you might as well procure a hole saw with an arbor adaptor. The saw consists of a threaded attachment where you can fit a small-sized hole saw.Buy from the best selection of arbor bits in the market today. Get a wide range of arbor bits from MRO Supply.
