Spade Drill Insert: 57/64" Dia, Seat Size 1, Cobalt MPN:181A-.890

Spade drill inserts are commonly used by construction workers or general contractors when drilling into concrete masonry blocks or walls with power drills. Due to their superior cutting ability, these drill bits provide a clean and fast way to create holes without cracking the material as they heat treated cobalt alloy maintains strength during heavy-duty applications thus extending usage lifespan even when encountering difficult concrete compositions. Their sharp spade point design makes them suitable for creating large diameter pilot holes or even smaller diameter precision drillings in concrete structures such as buildings, bridges, or other infrastructural developments. As such, construction companies and general contractors can count on these versatile bits' performance to get the job done quickly while reducing labor expenses since they provide excellent hole accuracy from start to finish resulting in fewer retakes thus minimizing costs overall associated with project completion schedules.
