Product Description
Milwaukee Guide Plate for 6 in. Thin Wall Core Bit
Model Number: 48-20-6163
The Milwaukee 48-20-6163 is a Guide Plate for Milwaukee 6 in. Thin Wall Diamond Core Bits — a precision drilling alignment attachment for the largest standard Milwaukee thin wall core bit size, ensuring accurate hole location during the initial engagement phase of 6 in. core drilling on concrete and masonry surfaces. At 6 in. diameter, accurate hole positioning is especially critical — the large bore affects a significant area of the concrete cross-section, and positional errors are more consequential and more costly to correct than at smaller diameters. The guide plate provides a stable centering surface dimensionally matched to the 6 in. thin wall core bit barrel outer diameter, preventing the bit walking and lateral drift that the large cutting circumference and heavy bit weight promote during the initial engagement phase before the kerf is established in the concrete surface.
The 6 in. thin wall guide plate is specifically dimensioned for Milwaukee 6 in. thin wall diamond core bits — it is a separate product from the 6 in. thick wall guide plate and the two are not interchangeable, 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 on the heavy 6 in. core bit assembly, for horizontal wall penetrations where perpendicularity is required, and for template-located holes where position accuracy determines installation conformance to construction drawings. Milwaukee offers guide plates across the full range of thin wall and thick wall core bit diameters for complete guide plate coverage throughout the Milwaukee core drilling system.
