The ELH 15 is a fast-cutting blade for cured concrete with medium-hard to hard aggregate. The ELH 35 is a fast-cutting blade for cured concrete with medium-hardness aggregate.The ELH 45 is a blade for soft aggregate concrete and abrasive building materials. • The innovative self-sharpening segment design means that the blade cuts at a maximum speed throughout its life. • The U-shaped segment design improves cooling and slurry transportation, for better blade speed and longer blade life. • Narrow water slots in the steel cores make cutting as smooth and even as possible. • The 415 mm diameter blade maximises cutting depth. • The small segment width (just 2.8 mm) allows very fast cutting.
