Circular saw blade Bosch 2 608 644 125 19 cm

The Bosch 2 608 644 125 circular saw blade is a 19 cm (190 mm) diameter cutting disc designed for use with handheld and table circular saws that accept a 30 mm bore. Engineered for cutting cement fibre panels, the blade combines a tooth geometry and carbide tipping suited to abrasive composite materials, enabling precise straight cuts with reduced chipping and consistent edge quality. The product is intended for trade professionals and DIY users who need a reliable accessory for working with fibre-cement boards and similar dense, mineral-based panels.

Advantages

The blade delivers stable cutting performance on cement fibre panels thanks to a robust tooth design and wear-resistant carbide tips that extend service life when used at recommended speeds. Its 190 mm diameter and thin kerf construction reduce material waste and require less power from the saw motor, while the 30 mm bore ensures compatibility with common arbor sizes when used with the correct adapter. The construction emphasizes clean cuts, minimized vibration, and predictable feed behavior on abrasive sheet products.

Suitable for

• Cutting cement fibre panels and fibre-cement siding
• Straight crosscuts and rip cuts in mineral-based boards
• Tradespeople installing external cladding or interior partition panels
• DIY projects involving cementitious composite sheets

Key specifications

• Diameter: 190 mm
• Bore size: 30 mm
• Material tip: carbide (for abrasive panel cutting)
• Suitable for cutting cement fibre / fibre-cement panels
• Designed for use on handheld and table circular saws with matching arbor

How to use

Install the blade on a compatible saw with a 30 mm arbor or use an appropriate reducer/adapter if required. Ensure the saw is disconnected from power while fitting the blade and that the blade is mounted with the rotation direction indicated on the disc. Select an appropriate blade speed and feed rate for cement fibre panels to avoid overheating; use steady, controlled feeds rather than aggressive forcing. Secure the workpiece and support cut pieces to prevent binding. Wear appropriate personal protective equipment including dust mask, eye and ear protection, and follow the saw manufacturer’s instructions for safe operation.

Usage recommendations

For best results, use this blade with dust extraction or in well-ventilated areas to manage silica-containing dust from cementitious panels. Match blade speed and feed to the board thickness and saw power; allow the blade to cool between long continuous cuts and replace the blade if cutting quality deteriorates or if visible wear appears on the carbide tips.
