Description

Revolutionize Your Multi-Tool Performance with Maximum Torque Transfer

The Bosch OSL212F-10 10-Pack 2-1/2 In. Starlock® Oscillating Multi-Tool Blades represents a new dimension in power and precision for professional contractors. Featuring the innovative Starlock® three-dimensional interface, these blades provide a completely integrated system between the tool and the accessory. Unlike standard flat interfaces, this 3D shape ensures maximum torque transfer and significantly reduces vibration, allowing for faster, more efficient cutting in demanding applications. While optimized for Starlock® tools, these accessories remain backward compatible with OIS® systems, fitting existing professional tools from Bosch, Fein, Milwaukee, Makita, Rigid, and more.

Engineered for versatility and endurance, these extra-wide 2-1/2 inch blades feature a bi-metal cutting edge designed to tackle wood with nails, drywall, PVC, and light-gauge metals. The blade incorporates Bosch's "Curved Tec" design, which features a rounded cutting edge that provides greater control and smoother, more precise plunge cuts with less vibration. Swiss-made for superior accuracy and long life, this bulk 10-pack ensures you have the high-performance blades you need to handle general-purpose cutting tasks on any job site.

Key Features

  • Starlock® 3D Interface: Provides best-in-class torque transfer and reduced vibration for extreme performance.
  • Bi-Metal Durability: Tough cutting edge slices through wood with nails, staples, PVC, and drywall.
  • Curved Tec Design: Rounded blade edge ensures smooth, precise plunge cuts and maximizes user control.
  • Universal Compatibility: Fits Starlock® tools and is OIS® compatible with most major brands (Fein, Milwaukee, Makita, etc.).
  • Color Coded System: Laser-etched blade and interface color help quickly identify the right blade for the material.
  • Swiss Precision: Manufactured in Switzerland to exacting standards for professional reliability.
  • Extra-Wide Cut: 2-1/2 inch width is ideal for cutting door jambs, baseboards, and wider framing.

Pro-Tip: The "Curved Tec" design allows for a rolling plunge cut, which is much smoother than forcing a flat edge directly into the material. To extend the life of your blade when cutting wood with nails, move the tool slightly side-to-side while cutting. This simple motion helps clear dust from the kerf and prevents heat buildup, which is the primary cause of blade dulling.
