Product Description
Milwaukee Spline Thick Wall Core Bit Adapter 12 in.
Model Number: 48-03-3564
The Milwaukee 48-03-3564 is a 12 in. Spline Thick Wall Core Bit Adapter — a standard working-length adapter that connects Milwaukee thick wall diamond core bits to Milwaukee Spline-drive demolition and rotary hammers for portable core drilling at the 12 in. working depth. The Spline shank is the drive interface on Milwaukee's larger-format demolition hammers for heavy-duty concrete work — this adapter allows the substantial impact energy of Spline-drive hammers to be applied to thick wall diamond core drilling using Milwaukee's thick wall core bit inventory. The 12 in. adapter length provides 12 additional inches of working depth beyond the standard core bit barrel length, enabling through-penetrations in concrete walls that a standard-length adapter cannot fully penetrate from a single accessible face position.
Milwaukee precision-machines both the Spline shank and the thick wall core bit mounting interface for accurate concentricity through the adapter — at 12 in. length, any eccentricity at the connection interfaces would produce measurable hole diameter variation and accelerated segment wear. The adapter is used with wet cutting throughout the operation, requiring adequate water delivery through the full extended system for segment cooling and slurry evacuation. Always verify that the hammer uses Spline drive — not SDS Max — before ordering, as the two shank systems are distinct and not interchangeable. This adapter is specifically for thick wall core bit systems, not thin wall.
See Milwaukee's complete Spline thick wall core bit adapter lineup including the 18 in. version (48-03-3565) for greater depth requirements.
