Bosch 2 608 837 770 Hoja de sierra circular 19 cm 1 ud.

The Bosch circular saw blade 19 cm is designed for cutting aluminium with precision and efficiency. With a 19 cm (190 mm) diameter and a 20 mm bore, this blade is made for mitre and sliding mitre saws commonly used in professional and DIY settings. The blade features an extra‑thin kerf and high‑quality carbide teeth that produce clean, accurate cuts while minimising energy draw on cordless saws. Expansion slots incorporated into the plate reduce noise and heat buildup during longer cuts, supporting consistent performance and tooth life.

Advantages

Extra‑thin kerf reduces power consumption and helps maximise battery runtime on cordless saws while maintaining cutting precision. Carbide teeth deliver durable, sharp cutting edges for clean finishes in aluminium. Expansion slots in the blade plate lower noise and dissipate heat, improving cutting stability and extending usable life. The central bore accommodates reduction rings, making the blade compatible with a wide range of mitre saw arbors.

Key specifications

How to use

Install the blade on a compatible mitre or sliding mitre saw following the machine manufacturer’s instructions, ensuring the arbor and any required reduction rings match the blade bore. Verify the blade is mounted in the correct rotation direction and securely tightened. Set appropriate cutting speed and feed rate for aluminium; allow the saw to reach full speed before engaging the workpiece. Use steady, controlled feed and avoid forcing the blade. After cutting, allow the blade to cool before handling or storing.

Recommendations

Wear appropriate personal protective equipment, including eye and hearing protection and gloves. Use cutting fluid or reduced feed when recommended for specific aluminium alloys to improve finish and reduce heat. Inspect the blade regularly for wear or damage and replace when carbide teeth are dull or chips are present. For cordless saws, choose a battery and motor combination rated for metal cutting to maintain efficiency and safety.
