7-1/2" Extension for Thick Wall Core Bits

Milwaukee 48-95-6085 — Core Bit Extension

The Milwaukee 48-95-6085 is a 7-1/2" extension for thick-wall core bits, used to increase drilling depth when boring large holes in masonry materials like concrete, brick, and block.

What it actually is

This is not a drill bit—it’s an extension accessory that connects between:

• your rotary hammer (SDS Max / spline setup)
• and a core bit

Its job is simple: give you extra reach when the hole needs to go deeper than the bit alone allows.

Key specs

• Length: 7-1/2"
• Shank: typically used with SDS Max or spline adapters
• Material: hardened steel
• Use with: thick-wall core bits (≈1-1/2" to 6" diameter range)

Key Features

• Heavy-duty steel construction – built for high-torque rotary hammer use
• Extends drilling depth – adds 7.5" reach to your core setup
• System compatibility – works with Milwaukee SDS Max or spline core bit systems
• Designed for thick-wall coring applications
