Achieve Flawless Plunge Cuts in Hardwood with Precision

The Bosch OSL212JF 2-1/2 In. Starlock® Oscillating Multi Tool Bi-Metal Blade is engineered to deliver the cleanest cuts possible in demanding hardwood applications. This "Xtra-clean" blade features a premium bi-metal cutting edge that resists wear and heat, ensuring longevity even when working with dense materials. A standout feature is the innovative "Curved Tec" blade design, which provides greater control and smooth, precise plunge cuts without the jarring vibration often associated with flat-edged blades. This makes it the ideal choice for finish carpentry, flooring installation, and cabinet work where surface finish is critical.

At the heart of this accessory is the revolutionary Starlock® interface, a three-dimensional fit system that eliminates play between the tool and the blade. This direct connection ensures maximum torque transfer and reduces vibration, allowing for faster work and higher precision. While designed for the next generation of Starlock tools, this Swiss-made blade is fully backward compatible with standard OIS® systems, fitting professional tools from Bosch, Fein, Makita, Milwaukee, and more. With its color-coded interface, you can instantly identify this blade as the specialist for hardwood cutting, keeping your workflow efficient.

Key Features

  • Xtra-Clean Finish: Specialized tooth geometry delivers tear-free cuts in hardwood and laminates.
  • Curved Tec Design: Rounded cutting edge ensures smooth, precise plunge cuts with minimal chatter.
  • Starlock 3D Interface: Provides maximum torque transfer and reduced vibration for superior performance.
  • Bi-Metal Construction: High-quality materials offer extended blade life in tough applications.
  • Universal Compatibility: Fits Starlock tools and is backward compatible with OIS oscillating tools (Fein, Milwaukee, Makita, etc.).
  • Swiss Engineering: Manufactured in Switzerland for professional-grade accuracy and durability.
  • Color-Coded System: Laser-etched markings and interface color help quickly identify material application.

Pro-Tip: The "Curved Tec" design works best when you gently rock the blade into the material rather than pressing straight down. This rocking motion engages the center teeth first and allows the outer teeth to follow, creating a precise pilot mark that prevents the blade from "walking" or skipping across your finished surface.
