Built for Cured Concrete
The Diamond Premium Wet Core Bit is engineered for demanding concrete coring rather than general-purpose drilling. Its diamond cutting construction is intended to provide extended drilling life and efficient cutting through cured concrete with hard aggregate and medium steel reinforcement.
The 7-inch diameter makes this bit suitable when a larger core opening is required for construction, mechanical, plumbing, or other building-service installations.
V-Shaped Turbo Segment
The V-shaped turbo segment is designed to increase cutting action as the bit works through the material. This geometry helps the bit maintain an efficient cutting path during wet coring applications.
Threaded Cap for Extended Drilling
A threaded cap allows the core bit to be extended when the application requires greater drilling depth. This provides additional flexibility for professional core drilling work without changing to a completely different bit design.
Wet-Use Design
This core bit is designed for wet use only. Water should be supplied during operation according to the drilling equipment and job requirements. Wet coring helps manage heat and supports the intended operating conditions of the diamond cutting system.
Compatible Equipment
The 7-inch Milwaukee Diamond Premium Wet Core Bit features a 1-1/4"-7 connection. Milwaukee identifies the Diamond Premium Wet Core Bit family as being designed for use with MX FUEL™ Core Drills and corded core drills. The 7-inch size falls within Milwaukee's 2- to 14-inch range, which uses the 1-1/4"-7 connection.
Always confirm that the drilling machine, arbor connection, operating speed, and wet-coring setup are suitable before use.
Typical Applications
The Milwaukee 48-17-3070 is suitable for professional applications such as:
- Concrete core drilling
- Mechanical installations
- Plumbing penetrations
- Electrical and utility penetrations
- HVAC installations

Package Contents
- 1 × Milwaukee 7 in. Diamond Premium Wet Core Bit

Important Usage Note
This is a wet-use-only core bit intended for compatible core drilling equipment. The 7-inch bit is relatively large and heavy, so it should be operated with properly rated equipment and appropriate drilling procedures. Do not exceed the manufacturer's specified maximum speed of 565 RPM.
