Metallics CSW71 7" x .045" x 7/8" Type 27 Cuto

The CSW71 is a 7 inch diameter cutoff wheel, .045 inch thick, with a 7/8 inch arbor hole, in a Type 27 (depressed center) shape. The 7/8 inch center is the standard arbor size for a 7 inch angle grinder, and the depressed center keeps the mounting hardware clear of the work so you can cut flush along a surface.

Yes, if the grinder takes a 7 inch wheel on a 7/8 inch spindle flange, which is the usual arrangement on 7 inch grinders. The CSW71 measures 7 inches across with a 7/8 inch center hole. It will not fit a 4-1/2 or 5 inch grinder, those take smaller wheels on a 7/8 inch arbor, and the guard will not clear a 7 inch disc.

It is a cutoff wheel, so use it for cutting only. At .045 inch thick it is built to slice, not to take side pressure, and leaning it over to grind an edge risks breaking the wheel. For material removal use a thicker Type 27 grinding wheel, typically 1/8 inch or 1/4 inch thick.

A .045 inch wheel removes less material per cut, so it goes through conduit, strut, threaded rod and all-thread faster and with less heat and burr than a thicker disc. That matters when you are cutting a lot of pieces to length on a rough-in. The tradeoff is that a thin wheel wears down quicker and should not be used for grinding or notching.

Type 27 has a depressed (raised) center, which recesses the mounting flange so the wheel face sits proud of the hardware. That lets you cut flush to a wall, floor or deck, and it is what most angle grinder guards are set up for. Type 1 is flat all the way across and is normally used on chop saws and stationary cutoff machines. The CSW71 is Type 27, so it is the angle grinder wheel.

Order Metallics CSW71. That is the manufacturer part number for the 7 inch x .045 inch x 7/8 inch Type 27 cutoff wheel, and it is the only model on the item, so there is no size, thickness or arbor option to specify.
