Milwaukee 49-94-4505 – Frequently Asked Questions
1) Will the Milwaukee 49-94-4505 cut-off wheel fit my 4-1/2 inch angle grinder?
It fits any 4-1/2 inch angle grinder that takes a 7/8 inch arbor, which is the standard spindle bore on that class of grinder. The wheel is 4-1/2 inches in diameter with a 7/8 inch arbor hole. If your grinder has a 5/8-11 threaded spindle with a hub-mount adapter rather than a plain 7/8 inch bore, you need a hubbed wheel instead.
2) Can I use the Milwaukee 49-94-4505 for grinding as well as cutting?
No. It is a cut-off wheel, built thin at .045 inches for cutting only. Side-loading a thin cut-off wheel for grinding or weld blending can shatter it. Use a Type 27 grinding wheel (typically 1/4 inch thick) or a flap disc for surface work.
3) What does Type 27 mean on a cut-off wheel, and does it change how I mount it?
Type 27 is the depressed-center (saucer) profile. The center hub is recessed, so the flange nut sits below the face of the wheel and you get clearance for flush and close-in work. It mounts the same way as a flat Type 1 wheel between the backing flange and lock nut, but the recess is what lets you cut up against an adjacent surface without the nut riding on the work.
4) Is a .045 inch cut-off wheel thin enough for cutting bolts and rebar without burning the stock?
Yes. At .045 inches the 49-94-4505 removes a narrow kerf, which keeps cutting time and heat buildup down on bolts, rebar, threaded rod and fasteners. Less material turned to dust also means less loss on parts you are cutting to length. For heavier sectioning where wheel life matters more than kerf width, a thicker 1/8 inch wheel holds up longer.
5) What metals is the Milwaukee 4-1/2 inch cut-off wheel intended for?
Ferrous metal stock is what it is built for: steel sheet, pipe, rebar, bolts and general fabrication work. It handles jobsite and shop metal cutting, maintenance and repair cuts. For aluminum, brass or other non-ferrous metals, use a wheel specified for non-ferrous, since ferrous-bonded abrasive loads up fast on soft metals.
