Curved and Radius Cutting with Diamond Blades: Techniques and Risks
Direct Answer: Attempting to cut curves or tight radii with standard flat diamond blades is extremely dangerous: lateral side pressure bends the steel core, causing blade binding, kickback, core cracking, and segment detachment. Curved or radius cuts must ONLY be performed using specialized concave dome diamond blades or contour blades engineered with curved steel cores.

Frequently Asked Questions
Why do flat diamond blades fail when cutting curves?
Flat steel cores cannot flex sideways inside a curved kerf. The edges pinch against stone walls, generating extreme heat and core warping.
