Mega Square CBN Wheel

The Most Versatile Flat-Profile CBN Wheel We Offer

The Mega Square CBN Wheel is designed for sharpeners who want maximum grinding surface and the ability to sharpen on both the face and side of the wheel. Its 1.5” wide profile makes it ideal for woodturners, woodworkers, knife makers, and anyone who prefers a flat grinding surface over a radius edge.

Unlike traditional grinding wheels, CBN wheels run cooler, maintain their shape, never require dressing, and provide consistent results from the first tool to the hundredth.

Whether you’re reshaping a damaged edge, establishing a new bevel, or putting the final edge on a favorite tool, the Mega Square delivers fast, repeatable results.
