Power through the most abrasive jobsite materials with the heavy-duty STIHL D-BA10 12" Premium Diamond Cutting Wheel. Engineered to be perfectly matched with compact STIHL cut-off machines, this elite diamond blade delivers incredible structural rigidity, long-lasting durability, and excellent precision during demanding slicing operations. It is optimized to give construction crews very high cutting performance when slicing through unforgiving, high-wear aggregate surfaces.
The D-BA10 model tier is specifically formulated with a resilient bond matrix that excels when cutting highly abrasive base materials. It is particularly suitable for asphalt, fresh concrete (green concrete), soft sandstone, cinder blocks, and structural brickwork. Unlike standard abrasive wheels that wear down rapidly under high friction, the segmented diamond design of the D-BA10 maintains its full 12-inch diameter throughout its entire operational lifespan, allowing for consistent, deep trenching cuts down to 3.9 inches deep.
Advanced Bond Matrix & Structural Safety: The laser-welded diamond segments feature an advanced formulation that resists the intense friction and scouring action caused by sandy aggregates and un-cured binders. This rigid core design eliminates wobbling and blade deflection, ensuring true, straight cuts while protecting the internal spindle bearings of your saw. For optimal tool performance, reduced operator fatigue, and compliance with jobsite dust regulations, this blade is designed for flawless integration with wet-cutting water dust suppression systems.
Compatibility Note: Features a standard 20 mm arbor size, making it a perfect fit for smaller gas-powered cut-off saws or modern cordless battery saws (such as the STIHL TS410, TSA 300) equipped with a 12-inch guard layout.
Key Features & Benefits
- Optimized for Abrasive Materials: Engineered specifically to tackle high-friction materials like asphalt, fresh green concrete, soft sandstone, and porous brick.
- Rigid Steel Core Design: High-tensile steel blade core resists warping, vibration, and deflection under heavy lateral loads to provide excellent precision.
- Laser-Welded Segments: Heavy-duty segmented cutting edge ensures structural durability and fast, aggressive material removal rates.
- Constant Outer Diameter: Retains its full 12-inch cutting profile for its entire working life, guaranteeing consistent, maximum-depth cutting capacity.
- High-Speed Efficiency: Tailored bond matrix exposes new diamond grits at the ideal rate, preventing blade glazing and maximizing cutting speeds.
- Universal 20 mm Arbor Setup: Precision-bored center hole ensures a safe, vibration-free balance match with factory STIHL safety spindles.
