Product Description
Milwaukee Thick Wall Core Bit Extension 7-1/2 in.
Model Number: 48-95-6085
The Milwaukee 48-95-6085 is a 7-1/2 in. Thick Wall Core Bit Extension — a barrel extension shaft that adds 7-1/2 in. of additional drilling depth to Milwaukee thick wall diamond core bits for through-penetrations in concrete walls, floors, and slabs where the combined material depth exceeds the standard barrel length of the thick wall core bit being used. This extension is specifically designed for Milwaukee thick wall diamond core bits — the thick wall barrel's larger wall section and diamond segment configuration require an extension manufactured to match these structural characteristics, unlike the thin wall core bit extensions that are not interchangeable with thick wall system components. Adding 7-1/2 in. of barrel extension enables drilling through thick concrete structural sections from a single drill setup position without the alignment challenges and extra time required for two-sided drilling from opposite faces of the penetration.
Milwaukee precision-machines the extension's connection interface for concentric rotation of the core bit system through the extension coupling — any eccentricity at the extension interface translates directly to hole diameter oversizing and non-uniform segment wear that shortens the expensive thick 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 to maintain diamond segment cooling and concrete slurry evacuation through the complete combined depth. Extensions can be combined for greater total depth on the thickest structural penetrations encountered in heavy commercial and industrial construction. Always follow Milwaukee's recommended procedures for core drill setup, feed rate, and water application when using barrel extensions.
See Milwaukee's complete thick wall core bit extension lineup for all available lengths and for the standard thin wall core bit extension series for thin wall system applications.
