Circular saw blade Proxxon 28017 — replacement blade for Proxxon saws, model 28017, compatible with small bench and portable circular saws

Proxxon 28017 is a circular saw blade designed as a replacement for Proxxon compact and benchtop circular saws. With a 50 mm diameter and 1.1 mm kerf, this blade is made for precise, low-waste cutting in workshop and hobby environments. The blade's 20 fine teeth deliver very clean cuts in thin materials such as balsa and plywood, and it can also be used for polymers like polycarbonate and printed circuit (PC) cards when mounted in compatible small circular saw units.

Advantages

The blade combines a small form factor with a fine-tooth geometry to minimize splintering and tear-out on delicate materials. Its thin body reduces material loss and heat buildup during short, accurate cuts. Designed for compatibility with Proxxon small bench and portable circular saws, the blade is balanced for steady rotation and consistent cut quality.

Suitable for

• Fine woodworking tasks using balsa, plywood and thin timber sheets
• Model making and hobby projects requiring precise edge quality
• Cutting plastic sheets such as polycarbonate and PCB/PC card material
• Replacement use in compatible compact or benchtop circular saws

Key specifications

• Overall diameter: 50 mm
• Blade thickness (kerf): 1.1 mm
• Bore (arbor) diameter: 10 mm
• Tooth count: 20 teeth, fine-tooth geometry
• Recommended materials: balsa, plywood, thin timber, polycarbonate, PC card material

How to use

Install the blade on a compatible small circular saw following the tool manufacturer's instructions, ensuring the saw is disconnected from power before changing blades. Use appropriate blade washers and secure the blade on the 10 mm arbor, checking that the blade is correctly oriented for the saw's rotation direction. For best results, clamp workpieces firmly, feed material at a steady, controlled rate, and avoid lateral pressure that could deflect the blade. Wear appropriate eye and respiratory protection when cutting dust- or particle-producing materials.

Usage recommendations

For the cleanest edges on thin wood and plastic, use slow to moderate feed speeds and support the workpiece close to the cut. Replace the blade if tooth damage or significant dulling is observed to maintain cut quality and reduce the risk of burning or chipping.
