Product Description
Milwaukee SDS+ Thin Wall Core Bit Adapter 12 in.
Model Number: 48-03-3551
The Milwaukee 48-03-3551 is a 12 in. SDS+ Thin Wall Core Bit Adapter — a standard-length adapter that connects Milwaukee thin wall diamond core bits to SDS+ rotary and combination hammers for portable core drilling without a dedicated core drill machine. The SDS+ shank provides the tool-free engagement convenience of the SDS+ system while transmitting the rotary and impact energy needed for thin wall diamond core drilling in concrete and masonry. The 12 in. adapter length provides 12 additional inches of total working depth beyond the core bit barrel's standard length, enabling through-penetrations in concrete walls that the standard adapter length cannot reach from a single drill position. This is particularly useful in commercial walls with thick concrete sections, multi-pour assemblies, and structural walls where the standard 6 in. adapter leaves the bit short of completion.
Milwaukee precision-machines the SDS+ shank and thin wall core bit mounting interface for accurate concentricity through the adapter — at 12 in. length, any eccentricity at the coupling interfaces would be amplified at the cutting face, producing oversized holes and accelerated segment wear on the thin wall core bits. The adapter is used with wet cutting throughout the operation, requiring adequate water delivery through the full system for diamond segment cooling and concrete slurry evacuation. Always verify that the SDS+ shank specification matches your hammer and that this adapter is designed for thin wall — not thick wall — core bit systems before ordering.
See Milwaukee's complete SDS+ and SDS Max thin wall core bit adapter lineup for all available lengths for through-penetration core drilling.
