Milwaukee SDS-Max Thick Wall Core Bit 12 in. Adapter Shank

The SDS Max Thick Wall Core Bit 12-Inch Adapter Shank is an ideal solution for when you need to drill holes into deep material. This SDS Max core bit adapter is 12 inches long， and can attach core bits anywhere from 1-1/2 inches to 6 inches long， for an overall reach of 18 inches. The steel construction of this adapter makes it durable enough to hold up under the most strenuous jobsite conditions. This drill bit adapter is designed for SDS rotary hammers， which direct their force into the bit rather than into the shank， and can cut into concrete or other tough materials. Core drill bits cut a hollow circle， which creates a hole of the same size with far less power or wear on the rotary hammer's motor.
