Product Description
Milwaukee Guide Plate for 5 in. Thin Wall Core Bit
Model Number: 48-20-6162
The Milwaukee 48-20-6162 is a Guide Plate for Milwaukee 5 in. Thin Wall Diamond Core Bits — a precision alignment attachment that improves core hole positioning accuracy during the initial bit engagement phase of 5 in. thin wall core drilling in concrete and masonry construction. The guide plate provides a stable centering surface dimensionally matched to the 5 in. thin wall core bit barrel's outer diameter, establishing the rotational axis at the exact intended hole center before the bit's diamond segments contact the concrete surface. Without the guide plate, a spinning large-diameter core bit walking laterally during the first seconds of engagement with hard concrete can position the core hole several millimeters or more from the intended center — an error that is costly to correct in large-diameter holes that affect significant portions of the concrete cross-section.
Guide plates are particularly valuable for the 5 in. diameter where accurate hole position directly impacts conduit alignment, sleeve fitting engagement, and structural integrity of the surrounding concrete section. For overhead drilling where gravity and bit weight combine to produce positional drift, for through-penetrations where the hole must align precisely on both faces for conduit or sleeve installations, and for template-located holes where position accuracy is specified by installation drawings, the guide plate provides a meaningful improvement over free-hand bit engagement in the critical initial engagement phase. The guide plate is specifically dimensioned for Milwaukee 5 in. thin wall diamond core bits — it is a separate product from the 5 in. thick wall core bit guide plate (48-20-5175) and the two are not interchangeable between bit wall thickness specifications.
