Product Description
Milwaukee Guide Plate for 1-3/4 in. Thin Wall Core Bit
Model Number: 48-20-6156
The Milwaukee 48-20-6156 is a Guide Plate for Milwaukee 1-3/4 in. Thin Wall Core Bits — a precision drilling guide attachment that improves hole location accuracy and core bit alignment during thin wall core drilling operations in concrete masonry and concrete where precise hole positioning is essential for the installation application. Accurate core hole placement is a critical quality factor in professional core drilling work — even small positional errors can result in conduit sleeve misalignment, anchor placement outside the specified structural zone, or core hole locations that require expensive concrete repair and re-drilling when they do not match the installation drawing dimensions. The guide plate provides a stable, positioned reference surface that aligns the core bit to the intended hole center before drilling begins, eliminating the bit walking and positional drift during bit engagement that occur when starting a core bit on hard concrete surfaces without positional guidance.
The 1-3/4 in. specification matches the outer barrel diameter of Milwaukee 1-3/4 in. thin wall diamond core bits — the guide plate is dimensionally matched to the correct core bit barrel size to provide the proper fit and alignment guidance that produces accurate hole positioning. Using a guide plate matched exactly to the core bit diameter provides full engagement of the guide plate with the bit barrel for concentric, accurate guidance throughout the critical initial engagement phase of the drilling operation before the bit has established its own position in the concrete. Guide plates are particularly useful for overhead drilling where gravity-induced bit drift is a challenge, for horizontal drilling in concrete walls where the bit must penetrate perpendicularly to the wall face, and for any application where hole location accuracy relative to a marked center point or template determines the quality of the installation.
Milwaukee's guide plate lineup covers additional sizes to match other thin wall and thick wall core bit diameters in the Milwaukee core drilling system — see the complete core drilling accessory lineup for all available guide plate sizes.
