AI Review Summary:

Across major retailers, buyers report clean, precise holes in ceramic tile and glass with notably better durability than generic bits. Many highlight fast starts and minimal chipping in marble and softer stone; some say using hammer mode on dense granite improves speed. Neutral feedback mentions slower progress on very hard granite and a learning curve to prevent wandering on glossy surfaces. Negative reviews cite premature dulling if used on porcelain or at high speeds without coolant. Representative quotes: “Went through marble like butter with clean edges,” “Works but takes patience on thick granite,” and “Dulls quickly on porcelain—use a diamond bit for that.”
