CGW 49547 7" X 5/32" X 7/8" ZA36 Type 27 36-Grit Zirconia Green Grinding Wheel

The CGW 49547 Zirconia Green grinding wheel is a 7-inch Type 27 wheel designed for heavy-duty metalworking tasks. It features a ZA36 premium zirconia grain combination that supports aggressive grinding action while aiming to maintain cooler operating conditions and reduce discoloration or warping of stainless steels. The wheel’s 36-grit size and R hardness are selected to balance material removal with control, offering a practical option for stainless steel, steel, hard face materials, titanium, inconel, and aluminum surfaces. The wheel is engineered to promote steadier operation with smoother, quieter performance and less operator fatigue compared with traditional aluminum oxide wheels, making it suitable for shops seeking efficiency in material removal with improved surface behavior.

This wheel’s construction is oriented toward a balance of fast cutting and material compatibility. The zirconia premium grain is intended to sustain efficient grinding while limiting heat buildup, an important consideration when working with heat-sensitive alloys. The Type 27 profile is compatible with grinders configured for depressed-center applications, and the wheel’s 7/8-inch arbor/shank size matches common mounting standards. For best results, follow standard wheel RPM guidelines; this wheel is rated for up to 8,500 RPM. In its packaging, the product is offered in sets as specified, with a package size of each and a box quantity of 25, which can support stocking and replacement planning in a facility setting.
