Product Description
Milwaukee Guide Plate for 6 in. Thick Wall Core Bit
Model Number: 48-20-5176
The Milwaukee 48-20-5176 is a Guide Plate for Milwaukee 6 in. Thick Wall Diamond Core Bits — a precision drilling alignment attachment for the largest standard Milwaukee thick wall core bit size that ensures accurate hole location during the initial bit 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, making positional errors 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. thick wall core bit barrel outer diameter, establishing the bit's rotational axis at the precise intended hole center before the heavy diamond segments contact the concrete surface and preventing the bit walking and lateral drift that the large segment mass and high cutting forces promote during initial engagement.
The guide plate is particularly important for overhead drilling where gravity acting on the heavy 6 in. thick wall core bit assembly contributes to positional drift during the initial engagement phase before the kerf is established, for horizontal wall penetrations where the hole must be perpendicular to the wall face for proper conduit alignment, and for template-located or drawing-specified penetrations where position accuracy determines installation conformance. Milwaukee offers guide plates across the range of thick wall and thin wall core bit diameters — the 6 in. thick wall version is specifically dimensioned for this largest standard thick wall bit diameter and is not interchangeable with guide plates for other sizes.
