20062 - SAIT A46N Aluminum Grinding Wheel Type 27 Depressed Center

Specialized Performance for Non-Ferrous Metals

The SAIT 20062 A46N Aluminum Grinding Wheel is a premium abrasive tool designed specifically to address the unique challenges of grinding soft, non-ferrous metals. Standard grinding wheels often fail when applied to materials like aluminum, copper, or brass because the soft metal melts and clogs the pores of the wheel—a process known as "loading." Once a wheel is loaded, it stops cutting effectively, generates excessive heat, and becomes dangerous to use. United Abrasives has solved this problem with the A46N formulation.

This 4-1/2 inch Type 27 wheel features a special aluminum oxide grain structure combined with a soft bond. This specific engineering allows the wheel to break down at a controlled rate, constantly exposing fresh, sharp grain while shedding the material that would otherwise clog the surface. The result is a consistent, aggressive cut that maintains its efficiency throughout the life of the wheel. For fabricators working with aluminum structures, tanks, or architectural elements, this means cleaner welds and faster surface preparation.

Safety and durability are paramount in the design of the SAIT 20062. The wheel is internally reinforced with the highest quality fiberglass, providing structural integrity under high-stress grinding conditions. Rated for a maximum speed of 13,300 RPM, it is compatible with standard 4-1/2 inch angle grinders featuring a 7/8 inch arbor. Whether you are smoothing out TIG welds on aluminum tubing or prepping brass fittings, this wheel delivers the reliability professional tradespeople demand.

Key Technical Benefits:

• Anti-Loading Technology: Prevents soft metals from gumming up the abrasive surface.
• Aggressive Removal: Soft bond ensures continuous cutting action without glazing.
• Extended Life: Outlasts many competitor wheels by up to 40%, reducing cost per cut.
• Versatile Application: Ideal for aluminum, copper, brass, and other non-ferrous alloys.
