30% Longer Lifetime - The titanium-coated Starlock ACZ 85 EIB blade has an extra 30% longer lifetime than uncoated BIM (bi-metal) blades. Its TiN (titanium-nitride) coated tooth strip is very heat- and wear-resistant, ensuring extra-long performance. Bosch's patented circular welding technology creates tough freestanding teeth, preventing jams and burn marks and allowing for extended usage. Use for plunge cutting in plasterboard, cement-bonded fibre boards, wood, non-hardened metal, small mouldings, fibreglass and epoxy-reinforced plastic. All Starlock, Starlock Plus and Starlock Max power tools as well as common multi-tools are compatible with the blade. The pointed segment saw blade ends enable cutting right into tight corners. The Starlock Snap-In mounting system allows fast blade removal and exchange within 3 seconds without having to touch the blade. The mounting system produces the highest power transfer thanks to a 3-dimensional tight-fitting connection between machine and accessory. Starlock mount for optimum power transfer and convenient blade change within 3 seconds.
