Product Description
Milwaukee Spline Thin Wall Core Bit Adapter 12 in.
Model Number: 48-03-3540
The Milwaukee 48-03-3540 is a 12 in. Spline Thin Wall Core Bit Adapter — a 12 in. length adapter for connecting Milwaukee thin wall diamond core bits to Milwaukee Spline-drive rotary and demolition hammers for core drilling without requiring a dedicated core drill machine. The Spline shank is the drive interface on Milwaukee's larger-format demolition hammers and rotary hammers used for heavy-duty concrete work — the Spline adapter allows the substantial impact energy of these larger hammers to be used for core drilling while using Milwaukee's thin wall diamond core bit inventory. The 12 in. adapter length provides additional working depth for core drilling through thicker walls and floor sections where the core bit barrel alone cannot complete a full through-penetration from the accessible face.
Milwaukee precision-machines both the Spline shank and the thin wall core bit mounting interface for the concentricity needed to maintain accurate core hole diameter and consistent diamond segment wear throughout the drilling operation — any eccentricity at either interface translates directly to cutting face runout. The 12 in. adapter is used with wet cutting throughout the operation, requiring adequate water delivery through the full adapter length to maintain segment cooling and concrete slurry evacuation. The Spline format is distinguished from the SDS Max format — verify that your hammer uses Spline drive rather than SDS Max before ordering this adapter, as the two shank systems are not interchangeable.
See Milwaukee's complete core drilling adapter lineup for SDS+ and SDS Max thin wall core bit adapters and for all available Spline adapter lengths.
