Durable Milwaukee 8 In Diamond Core Bit for Wet Concrete Cutting
Milwaukee 8 in. Diamond Premium™ Wet Core Bit – 48-17-3080
Product Overview
The Milwaukee 8 in. Diamond Premium™ Wet Core Bit (48-17-3080) is a professional core-drilling accessory designed for producing large, precise holes in cured concrete and reinforced concrete. It uses quality diamond cutting segments engineered to provide a combination of drilling speed and service life in demanding materials.
The 8-inch diameter makes this core bit suitable for larger penetrations commonly required for mechanical, plumbing, electrical, HVAC, and general construction work. Milwaukee specifically rates the Diamond Premium series for cured concrete with hard aggregate and medium steel reinforcement.
The bit features a V-shaped turbo segment for faster cutting action and a threaded cap that allows the core bit to be extended when deeper drilling is required. It is designed for use with MX FUEL™ Core Drills and compatible corded core drills.
Key Features
8-inch diameter for large-diameter core drilling applications
Premium diamond cutting segments designed for long drilling life and speed
Designed for cured concrete with hard aggregate
Suitable for concrete containing medium steel reinforcement
V-shaped turbo segment provides faster cutting action
Threaded cap allows the bit to be extended for deeper applications
15-inch drilling depth
1-1/4"-7 threaded arbor
400 RPM maximum speed
Designed for wet use only
Compatible with MX FUEL™ Core Drills and suitable corded core drills
Premium Diamond Cutting Performance
The Diamond Premium™ series is built around quality diamond cutting technology. The diamond segments are designed to maintain effective cutting performance as the bit works through cured concrete and hard aggregate.
For reinforced concrete applications, the bit is also designed to handle medium steel reinforcement. This makes the 48-17-3080 a practical choice when ordinary masonry drilling accessories are not appropriate for the size or material involved.
V-Shaped Turbo Segment
A V-shaped turbo segment is incorporated into the cutting edge to promote faster cutting action. This segment geometry is intended to help the bit efficiently remove material as it advances through the concrete.
The design is particularly useful for professional coring operations where maintaining productive drilling speed is important across multiple holes.
Threaded Cap for Bit Extensions
The 48-17-3080 features a threaded cap that allows the core bit to be extended. This provides additional flexibility when the standard 15-inch drilling depth is not sufficient for a particular application.
When deeper coring is required, use compatible extensions and follow the core-drilling equipment manufacturer's instructions to ensure the complete setup is properly supported and rated for the application.
8-Inch Diameter and 15-Inch Drilling Depth
With an 8-inch core diameter and 15-inch drilling depth, this bit is intended for large penetrations rather than small fastening or anchor holes.
Typical applications can include openings for:
Large plumbing lines
Electrical conduit and utility penetrations
HVAC installations
Mechanical systems
Commercial construction
Concrete renovation projects
Service penetrations through reinforced concrete
The actual achievable drilling depth can depend on the equipment, mounting arrangement, material, and use of appropriate extensions.
1-1/4"-7 Threaded Connection
The Milwaukee 48-17-3080 uses a 1-1/4"-7 thread. Milwaukee specifies that its Diamond Premium Wet Core Bits from 2 inches through 14 inches use the 1-1/4"-7 connection, while the smaller 3/4-inch through 1-1/2-inch versions use a 5/8"-11 connection.
Before purchasing, confirm that your core drill or drilling system accepts a 1-1/4"-7 threaded core bit.
Designed for Wet Core Drilling
This is a wet-use-only core bit. Water is used during the drilling process to help cool the cutting area and manage drilling debris.
Do not operate this bit as a dry core bit. A suitable wet-core-drilling setup should be used, and the water delivery method should follow the instructions for the compatible core drill.
