Product Description
Milwaukee 1-1/4 in.-7 Male to 5/8 in.-11 Female Core Bit Adapter
Model Number: 48-17-6008
The Milwaukee 48-17-6008 is a 1-1/4 in.-7 Male to 5/8 in.-11 Female Core Bit Adapter — a precision-machined thread adapter that allows core bits with a 5/8 in.-11 female mounting thread to be used on core drill machines, drill stands, and vacuum bases equipped with a 1-1/4 in.-7 spindle. The two thread standards are the most common core drill spindle interfaces in the professional market — the 1-1/4 in.-7 is used on larger core drill machines and vacuum base systems designed for larger-diameter core drilling, while the 5/8 in.-11 is used on smaller core bits, SDS+ adapter systems, and the smaller-format core drilling equipment. This adapter bridges the gap when the machine and bit use different thread standards, allowing a contractor to use 5/8 in.-11 threaded core bits on a 1-1/4 in.-7 spindle machine without purchasing duplicate bit inventory in both thread specifications.
Milwaukee precision-machines the adapter for accurate concentricity at both thread interfaces — any eccentricity at the adapter coupling translates directly to hole diameter variation and non-uniform segment wear at the cutting face. The adapter is used with wet cutting throughout the operation, requiring adequate water delivery through the system for segment cooling and slurry evacuation. Verify the adapter thread specifications match your specific core drill machine spindle and core bit female thread before ordering — adapters are not interchangeable between different thread combinations and the correct adapter must be selected for the specific machine and bit combination being used.
See Milwaukee's complete core bit adapter lineup for all available thread conversion combinations for Milwaukee and compatible core drilling equipment.
