Bosch Expert ACZ 85 RD4 Diamond Segment Saw Blade 85 mm

The Bosch Expert ACZ 85 RD4 is a diamond segment saw blade for Starlock-compatible oscillating multi-tools. It is designed for tile replacement and precise adjustment cuts during renovation work. The 85 mm blade diameter gives a useful cutting reach in tight spaces, while the 2 mm cutting width allows controlled material removal without damaging surrounding surfaces. The segment shape keeps the cutting line visible and helps when working close to corners and edges. This accessory is aimed at tradespeople who need to widen joints or make localised adjustments rather than carry out long rip cuts.

The blade uses a diamond cutting edge for abrasive materials. It mounts via the Starlock system, which holds it securely and transfers power efficiently from the tool. This fitting allows quick accessory changes on compatible multi-tools without the need for extra adapters. Each pack contains one blade, supplied as a ready-to-use unit. Its Starlock compatibility means it fits directly into existing tool systems from Bosch and other manufacturers. The construction is built to keep performing reliably during repeated renovation tasks.
