OVERVIEW

Industrial Grade Type 27 Cutting & Notching Wheel

The United Abrasives / SAIT 20906 is a premium 7-inch abrasive wheel designed for the rigorous demands of industrial metal fabrication. Engineered with a Type 27 depressed center profile, this wheel provides the versatility needed for both cutting and light notching applications, making it a staple in structural steel workshops, shipyards, and general construction sites. The wheel features a specialized .090-inch thickness, which strikes an optimal balance between the ultra-thin kerf of a standard cut-off wheel and the rigidity required for side-loading during notching tasks.

At the core of the SAIT 20906 is a high-quality Aluminum Oxide grain structure, bonded with a hard 'S' grade resin. This hard bond is specifically formulated to extend the life of the wheel, reducing the frequency of wheel changes and lowering overall consumable costs for high-volume operations. It performs exceptionally well on ferrous metals, including structural steel, iron, and welds. The depressed center design allows the operator to get the locking nut recessed, enabling flush cuts against workpieces without interference.

Safety and consistency are hallmarks of United Abrasives products. This wheel is reinforced to withstand the stresses of high-speed rotation (up to 8,500 RPM) while maintaining structural integrity. For industrial procurement managers looking for a reliable, long-lasting abrasive solution that minimizes downtime and maximizes material removal rates per dollar, the SAIT 20906 is a proven choice.

FAQ

Type 1 wheels are flat and used primarily for straight cutting. Type 27 wheels have a depressed center, allowing the locking nut to be recessed. This enables flush cutting and allows the wheel to be used for light notching and grinding at specific angles.

While Aluminum Oxide can cut stainless steel, this specific wheel is optimized for ferrous metals and mild steel. For stainless steel, it is often better to use a contaminant-free wheel (labeled for Stainless) to prevent potential corrosion or contamination of the weld zone.

A thickness of .090 inches is slightly less than 3/32". It is thicker than a standard .045" zip-style wheel, making it more rigid and suitable for notching or side-loading applications where a thinner wheel might flex or break, yet it is still thin enough to cut efficiently.

The SAIT 20906 7-inch wheel is typically rated for a maximum of 8,500 RPM. Always check the label on the actual wheel and ensure your grinder's speed does not exceed this rating.

The 'S' represents the hardness of the bond holding the abrasive grains together. 'S' is considered a hard bond, which means the wheel retains its grain longer, resulting in extended wheel life, though it may cut slightly slower than a softer bond.

No, Type 27 reinforced cutting/grinding wheels do not require a backing pad. They mount directly to the angle grinder using the appropriate flanges and locking nut.

This wheel is primarily designed for cutting and notching (.090" thickness). While Type 27 wheels can handle some side load, full face grinding is better suited for 1/4" thick grinding wheels to ensure safety and efficiency.
