## Long description

Bosch circular saw blade with a 190 mm diameter and 20 mm bore designed for cutting aluminium and other non-ferrous metals. The blade has tooth geometry optimised for clean cuts in sheet and profile work and is supplied as a single piece compatible with saws that accept 190 mm/20 mm metal-cutting blades.
Advantages
The blade’s fine tooth count and geometry reduce burrs and produce smooth edges on aluminium and similar metals. Its construction supports stable rotation at speeds up to 8000 RPM, helping maintain consistent cutting performance. Being compatible with Bosch systems ensures straightforward fitment on many standard circular saws that use 190 mm/20 mm blades.
Suitable for
Cutting aluminium sheets and profiles
Working with other non-ferrous metals
Metal fabrication and light workshop use
Precision trims and finish cuts on metal components
When it may not be suitable
This blade is designed specifically for aluminium and non-ferrous metals; it is not intended for cutting ferrous metals with heavy hardness, such as hardened steel, or for wood, plastics, or masonry. Using it on unsuitable materials can reduce blade life and impair cutting quality.
Key specifications
Diameter: 190 mm
Bore size: 20 mm
Number of teeth: 54
Recommended maximum rotational speed: 8000 RPM
Recommended material: aluminium and other non-ferrous metals
Quantity: 1 piece
How to use
Install the blade on a compatible circular saw with a 20 mm arbor, ensuring the blade’s rotation direction matches the saw’s arrow. Secure the blade flange and nut according to the saw manufacturer’s instructions, check that guards and safety devices are in place, and set an appropriate cutting speed and feed rate for aluminium to avoid overheating. Use steady, even feed pressure and allow the blade to complete the cut without forcing it to maintain edge quality.
What to consider before purchase
Ensure your saw accepts 190 mm diameter and 20 mm bore blades
Confirm the blade is suitable for non-ferrous metals rather than ferrous or wood
Check your saw’s maximum RPM to match or be below 8000 RPM
Usage recommendations
Use cutting lubricant or coolant when performing long or repeated cuts in aluminium to reduce heat buildup and extend blade life. Wear appropriate personal protective equipment and follow the saw manufacturer’s safety instructions.
