• Highlight: MK Diamond MK-225 premium grade 4-1/2" continuous rim blade — the same wet-cut MK-225 pattern used on full-size tile saws, sized down for handheld grinders.
• Best For: Tile installers making one-off curved cuts, plumbers cutting access holes, and contractors using 4-1/2" grinders for precise stone and ceramic detail.
• Expert Note: 4-1/2" MK-225 continuous rim is approved for wet OR dry use on grinders — but dry cutting always sacrifices blade life and increases dust, so use wet when feasible.
