High Performance Milwaukee 7 Inch Diamond Core Bit for Wet Drilling


Milwaukee 7 in. Diamond Premium Wet Core Bit


Product Overview


The Milwaukee 7 in. Diamond Premium Wet Core Bit is designed for professional wet coring applications in cured concrete, including concrete containing hard aggregate and medium steel reinforcement. Model 48-17-3070 uses a diamond-coated cutting surface and a V-shaped turbo segment to provide faster cutting action while maintaining long drilling life.


With a 1-1/4"-7 thread, this core bit is compatible with Milwaukee MX FUEL™ Core Drills and suitable corded core drills. It is specifically designed for wet use only and features a threaded cap that allows the core bit to be extended when deeper holes are required.


Key Features


  • 7-inch drilling diameter for creating large-diameter core holes.
  • Diamond-coated cutting surface designed for demanding concrete applications.
  • V-shaped turbo segments help provide faster cutting action.
  • Long drilling life in cured concrete with hard aggregate and medium steel reinforcement.
  • 1-1/4"-7 thread for compatibility with corresponding core drilling equipment.
  • Threaded cap allows extensions to be added for deeper drilling applications.
  • Wet-use design helps support cutting performance in demanding concrete coring work.
  • Compatible with MX FUEL™ Core Drills and appropriate corded core drills.

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
  • Commercial construction
  • Industrial construction
  • Drilling through reinforced concrete
  • Large-diameter concrete openings


Package Contents


  • 1 × Milwaukee 7 in. Diamond Premium Wet Core Bit
  • Model: 48-17-3070


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.


Why Choose the Milwaukee 7 in. Diamond Premium Wet Core Bit?


For contractors who need to produce large, clean core openings in cured concrete, the Milwaukee 7-inch Diamond Premium Wet Core Bit combines a diamond-coated cutting system, V-shaped turbo segments, threaded extension capability, and a 1-1/4"-7 connection. Its construction is specifically targeted at demanding concrete and reinforced-concrete coring applications where durability and cutting efficiency are important.
