Product Description
Milwaukee Guide Plate for 3-1/2 in. Thin Wall Core Bit
Model Number: 48-20-6160
The Milwaukee 48-20-6160 is a Guide Plate for Milwaukee 3-1/2 in. Thin Wall Diamond Core Bits — a precision drilling alignment attachment for accurate hole positioning during the initial engagement phase of 3-1/2 in. core drilling operations on concrete and masonry surfaces. The guide plate provides a stable centering reference dimensionally matched to the 3-1/2 in. thin wall core bit barrel outer diameter, establishing the bit's rotational axis at the exact intended hole center before the diamond segments contact the concrete surface and preventing the bit walking and lateral drift that can occur at this large diameter during initial engagement without a guide. At 3-1/2 in., the bit's weight and rotational momentum make initial positioning accuracy particularly important for maintaining the installation accuracy that engineering drawings require for the penetrations being drilled.
The 3-1/2 in. thin wall guide plate is specifically dimensioned for Milwaukee 3-1/2 in. thin wall diamond core bits — it is not interchangeable with the 3-1/2 in. thick wall guide plate as the barrel outer diameters differ between thin wall and thick wall configurations at the same nominal diameter. The guide plate is most valuable for overhead drilling where gravity acts against positioning accuracy, for horizontal wall penetrations where perpendicularity is specified, and for template-located penetrations where position accuracy determines system installation conformance. Milwaukee offers guide plates across the full range of thin wall and thick wall core bit diameters for complete alignment coverage throughout the Milwaukee core drilling system.
