The kerf is a narrow 1/16 inch (1.6 mm), enabling precise and clean cuts, particularly in grout lines and tight corners. This blade is designed for grout removal, mortar cleanup, and reworking joints in tiled surfaces, offering consistent performance across small projects.
EZARC Swing Diamond Blades DO57S, 3-Pack

These blades feature diamond grit technology with a flat-side swing design that improves access to tight spaces and corners. The kerf is about 0.09 inch (2.2 mm), delivering a precise cut without excessive tile damage. They are particularly effective for precise grout removal, edge work, and fitting around fixtures where space is limited.
AMZWEI 8Pcs Diamond Oscillating Blades

This 8-piece set includes long blades with curved edges for deep grout lines and precise cuts around tiles. The diamond-coated edge lasts significantly longer than carbide blades, offering durability for heavy-duty grout removal and mortar cleanup. The curved-edge design helps access corners and awkward seams while maintaining blade stability during operation.
PECHAM 9Pcs Diamond Oscillating Blades

PECHAM offers a versatile 9-piece kit with three blade types that handle grout removal, soft tile cuts, and precise edging. The 0.08 inch (2 mm) kerf enables clean, accurate cuts, while the flat-side swing design and semicircular blades improve access to corners and tight joints. This set is positioned for bathroom and kitchen tile projects where precision matters.
XXGO 4 Pcs Diamond Blades XG3304D

This 4-pack focuses on flush-cutting for grout removal with a design suitable for small jobs. While not intended for heavy granite cutting, these blades excel at tile grout removal and precise edge work. They pair well with standard oscillating tools for rapid grout cleanup and seam finishing.
Buying Guide
Key considerations when selecting an oscillating tool blade for tile, grout, and modest masonry work include blade type, wear resistance, kerf width, and blade reach. Diamond blades offer long life and precision in grout removal and tile edging, often outperforming carbide alternatives in tough materials. Consider blade geometry—flat-side swing designs help reach corners and tight seams, while curved-edge blades can improve control in larger grout lines.
Durability and compatibility are essential. Check blade compatibility with common tool brands (Dremel, Bosch, Makita, DeWalt, Milwaukee, etc.) and verify the attachment system. For grout removal, prioritize blades with a narrow kerf to minimize tile damage and achieve clean lines. Curved and semicircular designs are advantageous for entering recessed joints and edge work. In tight spaces, flat-side swing blades reduce obstruction and allow precise cutting near corners or between tiles.
Application scope varies. Use flush-cutting blades for finish work along tile edges and around fixtures, while longer blades with diamond grit excel at faster grout cleaning and mortar removal. Evaluate the project size: a compact 3–4 blade kit may be sufficient for bathroom renovations; larger sets provide more blade types for multiple textures and grout patterns. Always wear safety gear and follow tool manufacturer guidelines for optimal results.
Performance considerations also include user experience and blade life. Diamond blades tend to outlast carbide grit blades in grout-intensive tasks, reducing replacements. Some blades are designed specifically for grout removal and do not cut granite or hard walls, so match blade capabilities with the material you are working on. For best results, pair blades with a compatible oscillating tool and use steady, controlled motions to maintain edge integrity.
Environmental and cost perspectives matter too. Reputable brands offer longer-lasting blades, which can lower long-term costs despite higher upfront prices. If you are tackling a project with varied materials—tile, grout, and masonry—select a multi-pack that provides a balanced mix of blade widths, shapes, and kerfs to cover different seams and tile sizes.
