Our SDS MAX SLEDGE™ Chisels stay sharper longer, providing increased productivity and maximum life, as no re-sharpening or re-hardening is necessary, reducing our user's downtime. Our SLEDGE™ Chisels also feature reinforced edges to deliver maximum durability and reduced wear over the life of the chisel. Our MILWAUKEE® SDS MAX SLEDGE™ Chisels are designed for SDS Max rotary hammers with high-grade forged steel for maximum durability and longer life in concrete demolition over our standard chisels.
