Starrett Ulti-Mate Rapid Release Arbor System
Starrett Ulti-Mate offers super fast, tool free changes between different diameters of hole saw, without the
adjustment of the drill chuck. Removal of cores from a hole saw after a cut is also much improved by the rapidrelease of the hole saw from the arbor. Compatible with Constant & Dual Pitch Bi Metal, TCT Multi Purpose, Diamond and Tungsten Carbide Tipped Hole Saws.
How it works: Screw the appropriate adaptor onto the hole saw and push the hole saw and adaptor down the drill. When the hole saw and adaptor can be pushed no further, turn the hole saw and the collar will click on. Lock the holesaw on by turning the collar so the arrows on the base of the arbor and collar are not aligned. This will then lock the holesaw and arbor together.
To release the hole saw, align the arrow on the collar and the arrow on the base of the arbor and pull the collar back. The saw will then be released. The release is spring loaded so please take care when releasing the saw! Once the hole saw has come to the end of its useful life, the arbor adaptors can be reused, even if intensive use has resulted in the adaptors becoming very firmly attached to the hole saw. Just place the complete assembly in a vice, using the flats on either side of the arbor to hold the assembly still and unscrew the holesaw from the adaptor using a pair of grips or similar tool.
