Who benefits from this blade

- Drywall and plaster projects requiring precise, narrow-cut sections along edges and corners.
Use cases and practical tips
- Target grout lines between ceramic or porcelain tiles for quick, edge-friendly removal. The semi-circle edge helps you follow the grout line without gouging surrounding tile glaze.
- Resume work where traditional blades struggle — especially in tight joints and around irregular tile layouts.
- Operate your oscillating tool with steady, low-to-moderate speed and light, gradual passes to maximize blade life and minimize dust.
- Pair with a dust extraction attachment or vacuum to keep the work area clean and improve visibility during detailing.
- Protect surrounding materials by starting at the grout line edge and feeding the blade along the line rather than forcing it straight through the joint.
