Product Description
Milwaukee SDS Max Thick Wall Core Bit 18 in. Adapter Shank
Model Number: 48-03-3573
The Milwaukee 48-03-3573 is an 18 in. SDS Max Adapter Shank for Milwaukee Thick Wall Diamond Core Bits — an extended-length adapter that connects thick wall core bits to SDS Max rotary and demolition hammers for portable core drilling without a dedicated core drill machine, at the 18 in. length for through-penetrations in thick structural walls and floors where the standard-length adapter cannot complete the full penetration from a single drill setup. The 18 in. adapter length provides 18 additional inches of total system working depth beyond the core bit barrel's standard length, enabling through-wall drilling in thick concrete structures — heavy foundation walls, reinforced retaining walls, and multi-pour structural sections where the combined wall thickness requires this extended reach from a single accessible face position.
Milwaukee precision-machines both the SDS Max shank and the thick wall core bit mounting interface for accurate concentricity between the adapter and the core bit — any eccentricity at the long-length adapter coupling would be amplified into significant runout at the cutting face due to the extended lever arm of the 18 in. length, producing oversized holes and accelerated segment wear on the expensive thick wall core bits this adapter supports. The adapter is used with wet cutting throughout the drilling operation, requiring adequate water delivery through the full 18 in. adapter length for diamond segment cooling and concrete slurry evacuation. Always verify that the SDS Max shank specification matches your hammer before ordering, as SDS Max is distinct from the Spline drive format.
