Bosch 2 608 644 102 hoja de sierra circular 19 cm 1 ud.

The Bosch 2 608 644 102 circular saw blade has a 190 mm diameter and a 30 mm bore, engineered for precise cutting of aluminium and non-ferrous metals. Supplied as a single blade, it is intended for use with compatible circular saws and table saws. The design balances cutting speed and edge life to deliver clean, burr-free cuts and consistent performance across repeated operations.

Advantages

This circular saw blade combines a tooth geometry optimised for aluminium with hardened construction to reduce wear and maintain sharpness over time. Its 190 mm diameter provides a practical cutting depth for sheet metal, profiles and small sections, while the 30 mm bore fits common arbor sizes for secure mounting. The blade’s balance and finish minimise vibration during cutting, improving accuracy and reducing heat build-up in the workpiece.

Suitable for

• Cutting aluminium sheets and profiles
• Working with other non-ferrous metals (brass, copper)
• Precision work in metalworking shops and on-site jobs
• Use in handheld circular saws and bench/table saws with a matching arbor

Key specifications

• Diameter: 190 mm
• Bore (arbor) diameter: 30 mm
• Material suitability: aluminium and other non-ferrous metals
• Package quantity: 1 blade
• Designed for precision cutting with low vibration

How to use

Ensure the saw is disconnected from power before installing the blade. Fit the blade onto the saw arbor, making sure the bore aligns with the arbor and that the blade’s rotation direction marker matches the saw’s rotation. Tighten the mounting flange securely according to the tool manufacturer’s torque recommendations. When cutting, use steady feed rates appropriate for aluminium—avoid excessive force that can cause burrs or overheating. Allow the blade to run up to operating speed before engaging the workpiece and support the material firmly to prevent movement.

Recommendations

Use cutting lubricants or coolant when performing extended cuts in aluminium to reduce heat and extend blade life. Inspect the blade regularly for wear or damage and replace it when teeth are chipped or the cut quality degrades. Always follow machine and workplace safety guidelines, including appropriate personal protective equipment and secure clamping of workpieces.
