Circular saw blade Proxxon 28011 for precision cutting, metal-compatible, 28 mm bore

Proxxon 28011 circular saw blade for precision cutting is designed for fine mechanical work and detailed model-making. The blade has a compact diameter suited to small circular saws and rotary tools, enabling accurate, low-vibration cuts in thin materials. With a fine-toothed edge and slim body, it balances cutting precision and minimal material removal for controlled work on delicate parts and miniature assemblies.

Advantages

The blade’s 50 mm diameter and 10 mm bore provide compatibility with many compact tool spindles while keeping a stable mount for precision tasks. At 0.5 mm thickness and a fine-toothed profile, it produces narrow kerfs and reduced burr formation, which helps maintain component tolerances. Materials and tooth geometry are selected to handle fiberglass sheets up to 3 mm, non-ferrous metals, duro-plastics and other demanding materials commonly encountered in model-making and light engineering.

Suitable for

• Precision model-making and scale assembly
• Fine mechanical trimming and small-part fabrication
• Cutting thin non-ferrous metals (brass, aluminium)
• Working with fiberglass sheets up to 3 mm thickness
• Shaping duro-plastics and thin plastic parts

Key specifications

• Overall diameter: 50 mm
• Arbor / bore diameter: 10 mm
• Blade thickness: 0.5 mm
• Tooth type: fine-toothed profile for thin-kerf cuts
• Material compatibility: thin metals, fiberglass up to 3 mm, duro-plastics, wood and similar materials

How to use

Mount the blade on a compatible compact circular saw or rotary tool with a 10 mm arbor, ensuring the blade sits flush and is securely tightened before operation. Use appropriate rotational speeds for thin materials to avoid overheating; lower speeds often reduce burrs when cutting plastics and fiberglass. Support workpieces close to the cut line and feed slowly and steadily to maintain precision. After cutting metal or abrasive materials, inspect and clean the blade to remove residues that could affect subsequent performance.

Usage recommendations

Wear suitable eye and respiratory protection when cutting fiberglass or plastics, and use a clamp or fixture to secure small parts. For best results on non-ferrous metals, apply light cutting lubricant where appropriate and allow the blade to cool between extended cuts.
