Durable Milwaukee 8 in Diamond Core Bit for Wet Concrete Cutting
Milwaukee 8 in. Diamond Ultra™ Wet Core Bit – 48-17-5080
Product Overview
The Milwaukee 8 in. Diamond Ultra™ Wet Core Bit (48-17-5080) is a professional-grade core drilling accessory designed for making large, clean holes in concrete and reinforced concrete. Its thin-kerf, segmented diamond rim is engineered to remove material efficiently while maintaining a long working life.
Milwaukee combines high-quality diamond technology with a laser-welded construction to support demanding drilling applications, including concrete containing rebar and, when the application and equipment are appropriate, solid steel. Milwaukee states that the Diamond Ultra Wet Core Bit line can deliver up to 20% longer runtime than the previous generation of wet core bits.
With an 8-inch diameter, 16-inch drilling depth, and 1-1/4"-7 threaded connection, this core bit is intended for use with compatible MX FUEL™ Core Drills and corded core drilling machines.
Key Features
8-inch core diameter for creating large-diameter openings
Diamond Ultra™ cutting technology for fast and efficient coring
3 mm thin kerf segments help reduce the amount of material removed during drilling
Segmented diamond rim provides efficient cutting in concrete and reinforced concrete
10 mm diamond segment height for extended cutting capability
Laser-welded construction designed for demanding drilling applications
Up to 20% longer runtime compared with Milwaukee's previous generation of wet core bits
16-inch maximum drilling depth
1-1/4"-7 threaded connection for compatible core drilling equipment
330 RPM maximum speed
Wet-use design for controlled drilling and cooling
Compatible with MX FUEL™ Core Drills and corded core drills when the machine meets the required specifications
Diamond Cutting Technology
The Diamond Ultra series is engineered around high-quality diamond cutting technology. Rather than relying on conventional drill-bit flutes, the segmented rim continuously exposes cutting edges as the bit works through the material.
The 3 mm thin kerf is designed to help the bit make holes efficiently, particularly in reinforced concrete. The segmented design also supports faster material removal while the 10 mm segment height provides substantial diamond cutting material for demanding applications.
Designed for Concrete and Reinforced Concrete
This 8-inch core bit is particularly suited to applications where large penetrations must be made through concrete. Milwaukee identifies the Diamond Ultra line for concrete and rebar drilling, making it appropriate for professional construction, mechanical, electrical, plumbing, and infrastructure work where large-diameter cores are required.
The laser-welded construction is also designed for tougher applications, with Milwaukee specifically noting its suitability for applications that can include solid steel. Actual performance will depend on the drilling machine, material, drilling conditions, and correct operating procedure.
16-Inch Drilling Depth
With a rated 16-inch drilling depth, the 48-17-5080 provides substantial reach for deep coring applications. The core body is intended for professional core drilling setups rather than conventional handheld drilling.
The bit should be operated within the specifications of the connected core drill and should not be run above its 330 RPM maximum speed.
1-1/4"-7 Threaded Connection
The Milwaukee 48-17-5080 uses a 1-1/4"-7 thread. Milwaukee specifies that Diamond Ultra Wet Core Bits from 2 inches through 14 inches use the 1-1/4"-7 connection, while smaller 5/8-inch through 1-1/2-inch versions use a 5/8"-11 thread.
Always verify the arbor/thread specification of the core drill before installation. The thread size should match the machine or an appropriate manufacturer-approved adapter.
Wet-Use Design
This is a wet-use-only core bit. Water is used during the drilling process to help manage heat and drilling debris while supporting efficient cutting.
Because this bit is intended for wet coring, it should not be treated as a dry core bit. Follow the core drill manufacturer's instructions for water delivery, mounting, operating speed, and drilling technique.

The dimensional and weight specifications above are based on Milwaukee's published specifications and supporting distributor data. Grainger separately lists the overall length at approximately 18-11/16 inches, while Milwaukee's product specification page lists the product length as 8 inches; for this reason, the 18-11/16-inch figure is best understood as an overall assembled dimension rather than a core-body/drilling-depth measurement.
Typical Applications
The Milwaukee 8 in. Diamond Ultra Wet Core Bit is well suited for professional applications such as:
Large-diameter penetrations through concrete
Reinforced concrete coring
Plumbing penetrations
Electrical conduit and service openings
HVAC and mechanical installations
Construction and renovation projects
Infrastructure and utility work
Commercial building projects
Openings where a controlled, cylindrical core is required
Compatibility
The 48-17-5080 is designed for use with:
Milwaukee MX FUEL™ Core Drills
Compatible corded core drilling machines
Core drills equipped to accept a 1-1/4"-7 threaded connection
Milwaukee identifies its Diamond Ultra Wet Core Bit family as compatible with MX FUEL Core Drills and corded core drills for versatility across different coring setups.
Before use, confirm that the core drill has the required capacity for an 8-inch bit, supports wet coring, and is appropriate for the material being drilled.
