63162 - Pferd 4.5-Inch Type 27 Steel Cut-Off Wheel .040 Thickness

Technical Overview of the Pferd 63162 Cut-Off Wheel

The Pferd 63162 is a premium-grade abrasive cut-off wheel engineered for industrial steel applications. Featuring a diameter of 4.5 inches and an ultra-thin thickness of .040 inches, this wheel is designed to deliver rapid stock removal with minimal thermal impact on the workpiece. The abrasive composition utilizes high-quality aluminum oxide grain, selected for its hardness and durability, ensuring consistent cutting performance throughout the life of the wheel.

One of the defining characteristics of this model is its Type 27 (depressed center) geometry. Unlike standard flat Type 1 wheels, the Type 27 design features a raised hub that allows the locking nut to sit flush or recessed within the wheel's profile. This configuration is critical for operators who need to perform flush cuts or work in tight spaces where the grinder's mounting hardware would otherwise interfere with the workpiece. The depressed center also adds structural rigidity to the wheel, enhancing safety and stability during operation.

The .040-inch thickness is categorized as a thin cut-off wheel, often referred to in the industry for its slicing capabilities. This thin profile reduces the surface area in contact with the metal, resulting in less friction and heat generation. Consequently, this minimizes the heat-affected zone (HAZ) on the steel, reducing the likelihood of discoloration or metallurgical changes. It also translates to less material waste and lower power consumption from the angle grinder.

Designed specifically for steel, the bond matrix of the Pferd 63162 is optimized to break down at a controlled rate, exposing fresh abrasive grain to maintain a sharp cutting edge. This balance prevents the wheel from glazing over while ensuring it lasts long enough to be cost-effective for production environments. It is compatible with standard 4-1/2 inch angle grinders equipped with a 7/8-inch arbor.
