69855 - Pferd 5-Inch SG STEELOX Cut-Off Wheel Type 1 .045

Technical Overview of the Pferd 69855 Cut-Off Wheel

The Pferd 69855 is a high-performance abrasive cut-off wheel belonging to the SG STEELOX series, designed specifically for industrial applications requiring precision and efficiency. Measuring 5 inches in diameter with a thickness of .045 inches and a 7/8-inch arbor, this wheel is engineered to fit standard angle grinders. It utilizes a premium Aluminum Oxide grain structure that provides aggressive cutting action while maintaining structural integrity under load. The wheel is manufactured as a Type 1 (flat) profile, which is ideal for deep cutting operations where perpendicularity to the workpiece is essential.

One of the critical technical advantages of this wheel is its versatility across ferrous metals. It is formulated to cut both Carbon Steel and Stainless Steel (INOX) effectively. For stainless steel applications, the bond system is free of ferrous, chlorinated, and sulfurous fillers, ensuring that the cutting process does not introduce contaminants that could lead to corrosion or rust spots on the workpiece. This makes it a suitable choice for nuclear, food grade, and chemical processing equipment fabrication where material purity is paramount.

The .045-inch thickness is a key specification for modern fabrication. This ultra-thin profile reduces the surface area in contact with the metal, thereby generating significantly less friction and heat compared to thicker wheels. Reduced heat input preserves the metallurgical properties of the heat-affected zone (HAZ), minimizing discoloration and warping on thin-gauge materials. Furthermore, the reduced kerf width means less material is removed, translating to faster cut times and reduced power consumption from the grinding tool.

Durability is a hallmark of the Pferd SG elastic line. The 69855 is constructed with a hard bond that resists premature wear, even when cutting through solid cross-sections or hardened materials. Operators can expect consistent performance from the first cut to the stub, with a wheel that maintains its cutting edge without glazing. Safety is also prioritized, with reinforcement layers designed to withstand the lateral forces and high rotational speeds associated with right-angle grinding operations.

In summary, the Pferd 69855 represents a technically advanced solution for metal cutting, combining speed, life, and material compatibility in a single consumable. It is an essential tool for MRO professionals, structural fabricators, and pipefitters who demand reliability and precision in their abrasive consumables.
