Circular saw blade Bosch 2 608 837 770 19 cm

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.

Suitable for

• Cutting aluminium profiles, sheets and extrusions
• Mitre and sliding mitre saws (cordless and corded models)
• Workshops and on‑site metal fabrication tasks
• Precision trimming and crosscutting of non‑ferrous metals

Key specifications

• Blade diameter: 190 mm
• Bore diameter: 20 mm (compatible with reduction rings)
• Tooth material: carbide-tipped
• Kerf: extra‑thin for reduced cutting resistance
• Design features: expansion slots for heat and noise reduction
• Application: optimized for aluminium cutting

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.

Usage 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.
