Circular segment saw blade Bosch PRO ACZ 85 RT3, 85.0 mm diameter

Bosch PRO ACZ 85 RT3 is an 85.0 mm diameter circular segment saw blade made as an original Bosch accessory for compatible oscillating and multi-tools. Designed for compact cutting tasks, the blade enables plunge cuts, trimming and detailed work in wood, laminates and similar materials. Its small diameter and segment shape improve access in confined spaces and help deliver controlled, precise small-area cuts during renovation and finishing tasks.

Advantages

The compact 85.0 mm diameter and segment profile provide improved maneuverability and reach for confined or hard-to-access areas. As an original Bosch accessory, the blade is manufactured to fit compatible oscillating and multi-tools and maintain consistent cutting performance. The tooth geometry and cutting edge are optimised for clean results in wood and laminated surfaces, reducing tear-out when performing precision cuts and trims. The segment design also allows partial-edge cutting and easy plunge starts without having to pre-drill.

Suitable for

• Plunge cuts and small-area demolition in renovation work
• Detail trimming and finishing of wooden workpieces
• Cutting laminates, flooring trim and composite boards
• Access-restricted or tight-space cutting tasks

How to use

Select a compatible oscillating or multi-tool and secure the circular segment blade according to the tool manufacturer’s instructions. Mark the cutting line on the workpiece and position the blade for a steady plunge or trimming cut. Use controlled feed and steady hand pressure to maintain accuracy; allow the tool to reach operating speed before engaging the material. For best results in laminates and wood, cut at a steady pace without forcing the blade. Inspect the blade condition regularly and replace the blade if wear or damage affects cutting quality.

Recommendations

Use appropriate personal protective equipment, including eye protection and hearing protection, and ensure the workpiece is securely clamped. Verify tool compatibility and mounting orientation before operation. When working on finished surfaces, consider masking edges to reduce the risk of chipping. Store the blade in a dry place to prevent corrosion and avoid impacts that could damage the cutting edge.
