EXPAND YOUR CORING CAPACITY FOR LARGE-DIAMETER AGGREGATE PENETRATIONSWhen you're on a heavy civil site and the specs call for a 14-inch bore through reinforced concrete, you can't let your rig's standard clearance hold up the schedule. This 4-inch motor spacer block is the critical link required to bridge the gap between standard 10-inch capacity and the larger bits needed for heavy-duty utility and structural penetrations. Engineered for the high-torque environments of Dymo-Rig setups, this spacer mounts securely between the cradle and the motor, ensuring zero-flex stability during deep-hole coring operations where precision and structural integrity are non-negotiable. / Increases DYMO-RIG bit capacity from 10" to 14" for large-diameter structural boring. / Heavy-duty construction withstands the constant vibration and high-torque demands of industrial diamond drilling. / Precision-engineered to mount between the cradle and motor without compromising rig alignment or stability. / Direct compatibility with Milwaukee 4125, 4130, and 4136 diamond drill motors for seamless fleet integration.
