Drilling, Blasting, & Ripping

The profitability of your operation can depend largely on good blasting. Drilling and blasting are the first unit operations performed in most quarry and aggregate operations.  Proper drilling and blasting creates optimum material fragmentation and allows the downstream production process to operate at full capacity.

Walker Machinery offers a number of machines that deliver consistency and performance in every surface mining drilling application.  Our rotary drills and track drills – combined with multiple models of advanced drilling tools and our Halco high-performance hammers and drill bits – ensure there’s a Cat drill to meet every need.
