Circular saw blade Proxxon 28732 — 80 mm diameter, 10 mm bore, for metal/plastic/wood

Proxxon 28732 circular saw blade, 80 mm diameter with a 10 mm arbor, is engineered for precise cutting of a wide range of materials including wood, plywood, plastic, polycarbonate and soft aluminium. The thin 1.5 mm kerf and 36-tooth design enable clean, accurate cuts in small-scale workshop and model-making applications. Supplied as a single blade, it is intended for compact power saws and precision cutting tools that accept a 10 mm bore.

Advantages

The blade’s 80 mm diameter and fine 36-tooth configuration deliver smooth edges with minimal tear-out on thin materials. A 1.5 mm thickness provides a balance between rigidity and a narrow kerf to reduce material waste. The tool steel composition and tooth geometry are optimized for multi-material use, allowing reliable cutting of wood, plastics and soft metals without frequent blade changes.

Suitable for

• Model-making and hobby projects
• Workshop precision cuts on plywood and balsa
• Cutting polycarbonate and other plastics for small parts
• Light fabrication and trimming of aluminium sheets and PC cards

Key specifications

• Diameter: 80 mm
• Bore (arbor) diameter: 10 mm
• Blade thickness (kerf): 1.5 mm
• Tooth count: 36 teeth
• Suitable materials: wood, plywood, balsa, polycarbonate, plastics, soft aluminium

How to use

Install the blade on a compatible compact saw or precision cutter with a 10 mm arbor, ensuring the saw is disconnected from power before fitting. Tighten the arbor nut securely and confirm correct blade alignment and runout. Select an appropriate feed rate and cutting speed for the material—slower feeds for plastics and aluminium, moderate feeds for plywood and hardwoods. Use steady, even pressure and avoid forcing the blade to prevent overheating or chipping.

Usage recommendations

Wear appropriate eye and hand protection when cutting. For plastics and aluminium, reduce speed or use a lubricant/coolant for cleaner cuts and to extend blade life. Inspect the blade before each use and replace it if teeth are chipped or the blade is warped.
