Disco de serra circular Metabo 628443000 21,6 cm

The Metabo 628443000 circular saw blade with a diameter of 21.6 cm and a 3 cm bore is engineered for cutting aluminum with precision. Designed as a single-piece accessory for power saws, this blade offers robust construction and tooth geometry tuned to deliver clean edges and reduced burr formation when working with non-ferrous metals. Its balanced design supports steady rotation and minimizes vibration for improved cut quality and longer tool life.

Advantages

This circular saw blade provides accurate cuts in aluminum thanks to a profile optimised for non-ferrous metals, giving users smooth kerfs and consistent results. Durable materials and a stable build reduce wear and help maintain sharpness during repetitive cutting tasks. The product’s standard bore size and common diameter ensure compatibility with many stationary and portable saws, while its single-piece supply makes it convenient to replace or keep as a spare for workshop and jobsite use.

Suitable for (tasks / use cases)

• Cutting aluminium sheets, profiles and extrusions
• Fabrication and trimming of non-ferrous metal parts
• Workshop and on-site metalworking where clean edges are required
• Integration with circular saws and mitre saws adapted for metal cutting

Key specifications

• Blade diameter: 21.6 cm
• Bore (arbor) diameter: 3 cm
• Material suitability: aluminium and other non-ferrous metals
• Pack quantity: 1 piece

How to use

Install the blade on a compatible circular saw or mitre saw according to the machine manufacturer’s instructions, ensuring the correct orientation and secure fastening. Verify that the saw is set to an appropriate speed for aluminium cutting and use suitable coolant or lubricant if recommended for prolonged cutting tasks. Feed the workpiece steadily and avoid excessive pressure; allow the blade to cut at its designed rate to reduce heat build-up and burrs. Always disconnect power before changing the blade and inspect the blade for damage before each use.

Recommendations

Use appropriate personal protective equipment (eye protection, gloves, hearing protection) and consider a slow, controlled feed rate when cutting aluminium. For improved finish and blade life, employ cutting lubricant when making long or repeated cuts and ensure the saw’s guards and dust extraction are correctly positioned.
