The Bosch PRO ACZ 85 RT3 Multitool Blade uses tough carbide grit to ensure it's durable and effective when you work in abrasive materials. Great for removing old grout without damaging the tiles around. It can also be used for cutting cable channels in aerated concrete.

The Starlock mount provides optimum power transfer and convenient blade change within 3 seconds. The mounting system produces the highest power transfer due to a 3-dimensional tight-fitting connection between machine and accessory.
