Roundovers that reach where others can’t. Typical 1/2" bearing bits stop short in tight corners, leaving shoulders and breaks in your softened edges. Ultra-Shear Micro-Bearing Roundovers are engineered to solve that problem—keeping your edges smooth and continuous throughout the entire project. Available in 3/8", 1/4", 3/16", 1/8" and 1/16" radii, these bits let you: Furniture work: Ease edges cleanly into corners without start-and-stop shoulders.Scroll saw and CNC projects: Maintain consistent profiles even in the tightest inside corners. Unlike brass bushings that stick and burn, these are true ball-bearing pilots—the same micro-bearings that set Ultra-Shear apart. And with more radius profiles than any other manufacturer, you’ll always have the right bit for the job. To further protect your detail work, we added another innovation: a secondary bevel ground at the back of the carbide tip. This provides clearance and significantly reduces burning caused by bevel rubbing—so your profiles stay crisp and clean. Made in Strongsville, Ohio, every Ultra-Shear bit is built with: State-of-the-art CNC grinding equipmentHighest quality micro-grain and nano-grain carbideUltra-fine grinding wheelsSkilled Northeast Ohio machinists Don’t settle for imported shortcuts. With Ultra-Shear, you get American-made precision at an unbeatable price.
