Product Description
Milwaukee Thin Wall Core Bit Extension 7-1/2 in.
Model Number: 48-95-6070
The Milwaukee 48-95-6070 is a 7-1/2 in. Thin Wall Core Bit Extension — a barrel extension shaft for Milwaukee thin wall diamond core bits that adds 7-1/2 in. of additional drilling depth for through-penetrations in concrete walls and floors where the standard barrel length cannot complete a full through-penetration from a single drill setup. This extension is specifically designed for Milwaukee thin wall core bits — the thin wall barrel's smaller wall section and diamond segment configuration require an extension manufactured to match these structural characteristics, unlike the thick wall core bit extensions that are not interchangeable with thin wall system components. Adding 7-1/2 in. of barrel extension enables drilling through sections where the combined material depth exceeds the standard barrel's reach from the accessible drilling face.
Milwaukee precision-machines the extension's connection interface for concentric rotation through the coupling — any eccentricity at the interface translates directly to hole diameter variation and non-uniform segment wear that shortens the thin wall core bit's service life. The extension is used with wet cutting throughout the operation, requiring adequate water delivery through the full extended system length for diamond segment cooling and concrete slurry evacuation. Extensions can be combined for greater total depth on the thickest structural penetrations encountered in commercial construction. Always follow Milwaukee's recommended procedures for core drill setup, feed rate, and water application when using barrel extensions with thin wall core bit systems.
See Milwaukee's complete thin wall core bit extension lineup for all available lengths and for the thick wall core bit extension series for thick wall system applications.
