Jargon Buster

• OIS (Oscillating Interface System): A universal mounting standard allowing scraper blades to fit oscillating multi-tools from various manufacturers without requiring adapters.
• Starlock: Bosch's proprietary tool-free mounting system featuring a 12-point interface that provides enhanced torque transfer and secure blade retention during demanding applications.
• HCS (High Carbon Steel): A blade material offering excellent flexibility and durability, particularly suited for scraping softer materials like wood, plastic, carpet adhesive, and plaster.
• Rigid Scraper: A firm-bodied blade designed for removing hard, brittle materials such as tile adhesive, mortar, concrete residues, and solidified compounds without flexing.
• Flexible Scraper: A blade with controlled flex that contours to uneven surfaces, ideal for removing adhesives, sealants, and coatings from curved or irregular substrates.
• Oscillation Angle: The side-to-side movement range of the multi-tool, typically between 1.5° and 3.5°, which determines scraping speed and aggression.

How to Choose the Right OMT Scraper Blades

Mounting System Compatibility: Verify your oscillating multi-tool's mounting system before purchasing. Starlock blades fit Bosch, Fein, and other Starlock-compatible tools, whilst OIS blades offer universal fitment across most brands including DeWalt, Milwaukee, Makita, and Ryobi.

Blade Rigidity: Select rigid scraper blades for removing hard, brittle materials like tile adhesive, mortar, concrete splatter, and solidified compounds. Choose flexible scrapers when working on uneven surfaces, removing carpet adhesive, stripping sealants, or tackling applications requiring the blade to contour around curves and irregularities.

Blade Material: HCS (high carbon steel) blades provide excellent flexibility and durability for general-purpose scraping across wood, plaster, and soft adhesives. Stainless steel options offer superior corrosion resistance, making them ideal for wet environments, bathroom renovations, and applications involving moisture exposure.

Blade Width: Standard 52mm wide blades suit most applications, offering a balance between coverage and manoeuvrability. Consider your workspace constraints and the scale of residue removal required when selecting blade dimensions.

Application Demands: For professional tradespeople undertaking daily scraping tasks, invest in premium blades from Bosch Professional, Milwaukee, or DeWalt that offer extended service life and consistent performance. DIY users tackling occasional projects may find excellent value in quality options from Stanley, Faithfull, or Draper.

Pack Quantity: Blades dull with use, particularly when removing abrasive materials like concrete or tile adhesive. Purchasing multi-packs provides better value and ensures you maintain productivity without interruption during larger projects.

Safety Information

Always wear appropriate eye protection when using OMT scraper blades, as removed materials can become airborne projectiles. Safety goggles or face shields meeting BS EN 166 standards provide essential protection against debris, particularly when removing brittle materials like tile adhesive or concrete residues.

Wear suitable respiratory protection when scraping materials that generate fine dust, especially when working with old paints potentially containing lead, or adhesives containing harmful compounds. Masks rated FFP2 or FFP3 offer appropriate filtration for these applications, in accordance with HSE guidance.

Disconnect cordless tools from battery packs or unplug 240v corded models before changing scraper blades. Even with tool-free mounting systems, this precaution prevents accidental activation during blade changes. Ensure blades are securely fitted before operation, as loose attachments can detach during use, creating hazardous situations.

Maintain firm control of your oscillating multi-tool throughout scraping operations, keeping both hands on the tool when possible. The oscillating action can cause the tool to shift unexpectedly when encountering variations in material hardness, particularly when removing solidified adhesives or mortar.

Frequently Asked Questions

Are Starlock blades compatible with OIS multi-tools?
No, Starlock is a proprietary Bosch system featuring a 12-point interface, whilst OIS uses a different universal mounting design. Always verify your multi-tool's mounting system before purchasing blades. Some manufacturers offer adapters, but direct-fit blades provide the most secure connection and optimal performance.

How long do OMT scraper blades typically last?
Blade lifespan varies considerably depending on the materials being removed and application intensity. Scraping soft adhesives may allow several hours of use, whilst removing abrasive materials like tile adhesive or concrete can dull blades within 30-60 minutes of intensive work. Professional tradespeople often keep multiple blades on hand for uninterrupted productivity.

Can I sharpen dull scraper blades?
Whilst technically possible using fine files or sharpening stones, the time investment rarely justifies the effort given the modest cost of replacement blades. Most professionals simply replace dulled blades rather than attempting restoration, ensuring consistent performance and work quality.

What's the difference between rigid and flexible scraper blades?
Rigid scrapers feature firm bodies that resist flexing, making them ideal for removing hard, brittle materials like tile adhesive and mortar without bending. Flexible scrapers incorporate controlled flex, allowing them to contour around curves and irregular surfaces whilst removing softer adhesives, sealants, and coatings.

Do I need different blades for wet versus dry scraping?
Standard HCS blades perform adequately in both conditions, but stainless steel options provide superior corrosion resistance for applications involving consistent moisture exposure, such as bathroom renovations or outdoor work. The choice depends more on environmental conditions than the wet or dry state of the material being removed.
