Best Multi Tool Blade For Plaster: Top 6 Picks

Removing plaster, grout, or mortar often leads to rough edges and uneven finishes, especially with standard blades. A specialized diamond blade ensures a cleaner, more controlled cut, reducing the risk of damaging surrounding materials.

The EZARC Diamond Oscillating Blade stands out for its long-lasting diamond edge, making it a strong choice for anyone focused on precision and durability. It's ideal for home renovators and DIYers who want professional-looking results without constant blade changes.

• Diamond cutting edge delivers up to 5x longer life than carbide grit blades, minimizing replacements
• 1/16 inch kerf enables clean, accurate cuts, especially in tight spaces and corners
• Universal fitment with included adapters suits most major oscillating multi-tool brands

Compared to basic carbide blades, this model prioritizes clean, flush cuts and extended lifespan. The tradeoff is that it may cost more upfront, but it pays off in reduced blade changes and improved finish quality.

Tackling a range of plaster, grout, or mortar jobs often requires more than one blade type. Many users struggle with blades that are either too thick for narrow gaps or not robust enough for larger surfaces.

The LEILUO 6Pcs Diamond Multi Tool Blades Kit offers both flat and crescent-shaped blades, making it a flexible option for those handling varied renovation tasks. It's especially useful for homeowners or contractors who want a ready-to-go assortment for different scenarios.

• Flat and crescent blade mix covers both narrow gap access and general surface work
• Diamond grit edge ensures effective grout removal and plaster cutting
• Wide compatibility fits most quick-release and non-quick-release oscillating tools

Unlike single-blade packs, this kit prioritizes versatility and value. The main tradeoff is that it does not support Starlock systems and some Dremel models require an adapter.

When a project involves more than just plaster—like wood, metal, or drywall—switching blades can slow you down and complicate the job. A multi-material blade streamlines the process, letting you move between tasks without interruption.

The EZARC Obsidian Carbide Oscillating Saw Blades are designed for those who want one blade to handle a range of materials. With advanced carbide teeth and a TiCN coating, it's a practical pick for users who value efficiency and durability across different surfaces.

• TiCN coating improves edge retention and blade durability for extended use
• Optimized carbide teeth handle wood, metal, plasterboard, and more
• Universal compatibility fits most major oscillating tool brands (except Starlock)

Compared to dedicated plaster blades, this option prioritizes flexibility and speed. The tradeoff is that it may not deliver the absolute cleanest cut in plaster, but it excels for users needing all-in-one convenience.

General home repairs often involve cutting through a mix of plaster, wood, and even metal. Using the wrong blade can lead to premature wear or poor results, especially on tougher materials.

The EZARC Carbide General Purpose Oscillating Blades are built for users who need one blade to cover most household tasks. Its carbide technology and integrated depth gauge make it a practical choice for those who value convenience and accuracy.

• Carbide laser welding increases blade strength and longevity
• Integrated depth gauge allows for precise, repeatable cuts
• Universal interface works with most oscillating tools (not Starlock)

Compared to specialized blades, this model prioritizes all-around utility and ease of use. The tradeoff is that it may not be as long-lasting as premium diamond blades in heavy plaster removal.

Removing grout or plaster from narrow joints can be challenging with standard blades, often resulting in incomplete removal or damage to adjacent tiles. A blade sized for 1/8" grout lines offers better control and efficiency.

The XXGO 4 Pcs Diamond Grout Blades are tailored for users working with 1/8" grout lines or similar-width plaster joints. They're a solid pick for tile repair, joint cleaning, and detailed renovation work.

• 2.2mm thickness matches 1/8" grout lines for precise removal
• Diamond grit handles plaster, mortar, and grout efficiently
• Broad compatibility fits most major oscillating tool brands

Compared to thicker or more general-purpose blades, this set prioritizes accuracy in narrow spaces. The tradeoff is that it's not ideal for very fine (1/16") grout lines or hard wall tile cutting.

Frequent grout or plaster removal can quickly wear out blades, leading to repeated purchases and downtime. Buying in bulk ensures you always have a replacement on hand for ongoing or large-scale projects.

The XXGO 20 Pcs Diamond Grout Removal Blades are ideal for contractors, property managers, or anyone tackling multiple renovation jobs. The generous quantity means less worry about running out mid-project.

• 20-piece pack provides ample supply for repeated use
• 2.2mm thickness works well with 1/8" grout lines
• Diamond grit handles plaster, mortar, and grout efficiently

Compared to single or small packs, this set prioritizes value and convenience for high-volume users. The tradeoff is that it's not suitable for very fine grout lines or hard wall tile cutting.
