61304 - Pferd SG Aluminum Grinding Wheel 7" x 1/4" Type 27

Professional Grade Aluminum Grinding Solution

The Pferd 61304 Performance Line SG Grinding Wheel is a specialized abrasive tool engineered specifically for the challenges of working with aluminum and other non-ferrous metals. In industrial fabrication, standard grinding wheels often fail when applied to aluminum because the soft metal melts and adheres to the abrasive grain—a process known as "loading." This glazing effect reduces cutting efficiency and increases heat buildup. Pferd has addressed this issue with their proprietary N-ALU bond, a soft yet durable formulation that sheds worn grain and resists metal adhesion effectively.

This 7-inch wheel features a standard 1/4-inch thickness and a 7/8-inch arbor, making it compatible with most heavy-duty angle grinders used in shipyards, trailer manufacturing, and structural aluminum fabrication. The Type 27 depressed center design allows for optimal approach angles (typically 30 to 45 degrees) for aggressive stock removal and weld leveling. Unlike some competing products that require the application of wax or tallow to prevent clogging, the Pferd 61304 is designed to run dry. This is a critical advantage for welding operations, as it ensures the workpiece remains free of paraffin or grease residues that could introduce porosity or inclusions in subsequent welding passes.

Operators will appreciate the balance of aggressive removal rates and extended service life. The wheel maintains its cutting profile longer, reducing the frequency of wheel changes and downtime. Whether working on soft, tough, or hard aluminum alloys, this wheel delivers consistent performance without the vibration and chatter associated with loaded wheels.
