Product Description
Milwaukee 3/8 in. Pull-Back Arbor with Retractable Starter Bit
Model Number: 49-56-7235
The Milwaukee 49-56-7235 is a 3/8 in. Pull-Back Arbor with Retractable Starter Bit, the arbor that drives Milwaukee Diamond Max hole saws for cutting hard materials like porcelain tile, stone, and dense masonry. The arbor threads onto a Diamond Max hole saw and chucks into a drill by its 3/8 in. shank, and it is built around two features that solve the usual problems of diamond hole sawing. A retractable carbide starter bit at the center creates a divot that keeps the saw from walking across a slick tile surface, so the cut starts exactly where it is marked, and because the bit retracts, no separate pilot hole is needed. It fits all Milwaukee Diamond Max hole saws from 1-1/4 in. to 4-1/2 in.
The pull-back part of the name is the arbor's pin design. Diamond hole sawing runs at high torque, and a standard threaded arbor tends to bind, with the hole saw screwing itself tight onto the arbor so hard that it strips the threads or will not come off. Milwaukee's pull-back pins engage the hole saw and take that torque on the pins instead of letting it lock down the threads, which prevents binding and thread stripping and lets the operator swap hole saws quickly by hand. On a job where several hole sizes get cut, that faster, no-struggle change is a real time saver, and it protects both the arbor and the hole saw from the thread damage that ends their life early.
The retractable starter bit creates the center in hard materials without the walk, drift, or cracked tile that comes from trying to start a diamond hole saw dry on glazed porcelain, so it is a practical setup for plumbers, electricians, tile setters, and remodelers running fixtures, pipe, and conduit through tile and stone. The arbor ships as a single piece, the 3/8 in. Pull-Back Arbor with Retractable Starter Bit, ready to pair with Diamond Max hole saws. As an authorized Milwaukee dealer, Great Lakes Power Tools supplies it genuine.
