Combating Abrasive Undercutting in High-Sand Concrete Mixes

Direct Answer: Concrete mixes containing soft high-sand aggregates or uncured green concrete generate sharp abrasive slurry that washes against the steel core below diamond segments, causing undercutting failure. Combat undercutting by specifying hard nickel-alloy bond matrix blades equipped with recessed drop segments or carbide core inserts that deflect slurry away from the weld line.
