This Bosch PRO Cordless Circular Saw Blade for Aluminium is the 165mm diameter, 54-tooth variant with a 20mm bore, providing a larger spindle fitment option for the 165mm blade size, suitable for a wider range of cordless circular saw platforms. The extra-thin kerf reduces friction and lowers energy consumption during cutting, helping your cordless tool’s battery last longer on site. Its 54 individually shaped, ground, and sharpened carbide teeth — crafted from premium carbide grains — deliver precision and durability when cutting aluminium sections and profiles. Expansion slots integrated into the blade dissipate heat and reduce noise during extended use, helping to maintain blade integrity over time. The 20mm bore is designed for use with or without reduction rings for flexible compatibility with different saw spindle sizes.
