Milwaukee SDS-MAX and SPLINE Thin Wall Carbide Tipped Core Bit 5-in. (48-20-5060)

The Milwaukee 48-20-5060 SDS-MAX and SPLINE Thin Wall Carbide Tipped Core Bit 5" is a masonry core bit for drilling large through-holes in brick, block, and concrete. This is a masonry core bit designed for drilling large through holes. Model number 48-20-5060. If you need a larger opening than a standard hammer drill bit can handle, this is the right type of accessory for the job.

The big selling point here is capacity with control. The 5 inch diameter is sized for larger penetrations, while the thin wall construction helps keep the cut efficient instead of forcing the tool to remove more material than necessary. Milwaukee lists a usable cutting depth of 2-13/16 inches and a drilling depth of 3 inches, which makes this core bit a practical fit for common masonry wall penetrations where you need a clean, repeatable opening.

This is not just a bare cutting cup. Milwaukee includes the core bit body, guide plate, and centering pin, which matters because those pieces help the bit start where you want it and stay on track at the beginning of the cut. On larger diameter masonry drilling, startup control is a real issue. Having the proper guiding components in the package saves time and helps reduce wandering when you begin the hole.

The bit is built for SDS-Max or spline rotary hammer systems, but it requires the correct adapter shank for the setup you are using. Milwaukee specifies compatibility with the 12 inch Spline Adapter Shank 48-03-3540 or the 12 inch SDS Max Adapter Shank 48-03-3574. If your application needs more reach, Milwaukee also notes compatibility with the 7-1/2 inch Extension 48-95-6075. That gives this core bit a useful place in a larger concrete drilling system instead of being a one-off accessory.

In practical terms, this Milwaukee core bit is for tradespeople who regularly drill masonry openings and want the right accessory instead of trying to oversize a standard bit or chip out an opening after the fact. It is especially useful when you need a consistent diameter hole in block, brick, or concrete and you are already working with an SDS-Max rotary hammer or a spline setup.

If you are a contractor, maintenance crew, or serious remodeler dealing with masonry penetrations, the Milwaukee 48-20-5060 SDS-MAX and SPLINE Thin Wall Carbide Tipped Core Bit 5" makes sense because it is purpose-built for that exact job. It is not meant to replace small diameter hammer drill bits. It is for the bigger hole where clean sizing, proper guidance, and system compatibility matter.
