Norton 66253246883 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253246883 is a Type 5 vitrified aluminum oxide surface grinding wheel rated for demanding material removal on ferrous and non-ferrous workpieces. At 14 inches in diameter and 2 inches thick with a 5-inch arbor hole, this wheel fits full-size surface and cylindrical grinders used in production and toolroom environments. The 46-grit coarse grade removes stock aggressively, while the J hardness code and vitrified bond provide a consistent, controlled cut. Maximum operating speed is 2,320 RPM. Specification code 46J8V32A confirms the abrasive type, grade, bond, and series for traceability. Weight is 11.43 pounds.

This wheel is suited for shop applications that require heavy stock removal across a range of materials. Typical installation scenarios include surface grinder and cylindrical grinder setups in tool-and-die shops, maintenance facilities, and metal fabrication operations. The one-side recess configuration, with an 8-inch recess diameter and 1-inch recess depth, clears hub interference on compatible spindle flanges. The wheel color is blue and gray.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or toolroom technician following ANSI B11.9 and applicable shop safety standards. Inspect the wheel for cracks or chips before mounting and perform a ring test per standard practice. Power down and lock out the grinder spindle completely before changing wheels. Never exceed the 2,320 RPM maximum speed rating marked on the wheel.
