Durable Milwaukee 9 in Diamond Core Bit for Wet Concrete Cutting
Milwaukee 9" Diamond Premium Wet Core Bit
Product Overview
The Milwaukee 9" Diamond Premium Wet Core Bit, model 48-17-3090, is a professional-grade diamond core bit designed for drilling large-diameter holes in cured concrete and concrete containing medium steel reinforcement. It combines a diamond-coated cutting surface with a high-carbon-steel construction to provide the durability and cutting performance required for demanding coring applications.
With a 9-inch diameter, 15-inch drilling length, and 1-1/4"-7 threaded connection, this core bit is designed for use with compatible MX FUEL™ Core Drills and corded core drilling equipment. Milwaukee specifically rates this size for a maximum speed of 505 RPM and specifies it for wet use only.
A V-shaped turbo segment is incorporated into the cutting design to promote faster cutting action, while the threaded cap allows the bit to be extended when additional drilling depth is required.
Key Features
9-inch cutting diameter for producing large core holes.
15-inch drilling depth for substantial coring applications.
Diamond-coated cutting surface designed for demanding concrete work.
High-carbon-steel construction for the core bit body.
V-shaped turbo segment promotes faster cutting action.
1-1/4"-7 threaded connection for compatible core drilling machines.
Threaded cap allows the bit to be extended when greater depth is required.
Designed for cured concrete with hard aggregate and medium steel reinforcement.
Compatible with MX FUEL™ and corded core drills for added equipment flexibility.
Wet-use design helps support the intended drilling method.
Maximum rated speed of 505 RPM for this 9-inch size.
Built for Cured Concrete and Reinforced Applications
The Diamond Premium series is designed for demanding coring work in cured concrete, including applications involving hard aggregate and medium steel reinforcement.
The diamond cutting surface provides the abrasive cutting action necessary for core drilling, while the V-shaped turbo segment is intended to improve cutting speed as the bit advances through the material. Milwaukee positions these bits for applications where both drilling life and cutting speed are important.
For reinforced concrete work, the bit should be operated with the appropriate compatible core drill, water supply, RPM, and drilling procedure specified by the equipment and bit manufacturers.
V-Shaped Turbo Segment
The V-shaped turbo segment is one of the key design elements of the Milwaukee Diamond Premium Wet Core Bit.
Its segmented cutting profile is designed to provide a faster cutting action compared with a conventional continuous cutting configuration. This can be particularly useful when drilling larger holes where maintaining efficient material removal is important.
Threaded Cap for Bit Extension
The bit features a threaded cap that allows the core bit to be extended when additional drilling depth is required.
This design provides contractors with an option to increase drilling reach without replacing the entire core bit with a longer one. Proper extension components must be selected according to the compatible core drilling system and manufacturer's requirements.
1-1/4"-7 Threaded Connection
The 48-17-3090 uses a 1-1/4"-7 threaded arbor connection.
Milwaukee's Diamond Premium Wet Core Bit range specifies that sizes from 2 inches through 14 inches use the 1-1/4"-7 thread, while the smaller 3/4-inch through 1-1/2-inch sizes use a 5/8"-11 connection. This makes the 9-inch bit part of Milwaukee's larger-diameter core drilling range.
Always verify that the core drill has the correct spindle/thread configuration before installation.
Designed for Wet Coring
The 48-17-3090 is designed for wet use only. Water is used during the intended drilling process to help manage heat and drilling conditions.
Because this is a wet-use core bit, it should not be treated as a dry core bit. Use an appropriate water-delivery system and follow the operating requirements of the compatible core drill.
Compatibility
Milwaukee designed the 9" Diamond Premium Wet Core Bit for use with MX FUEL™ Core Drills and compatible corded core drills. The 1-1/4"-7 thread makes it suitable for core drilling equipment that accepts this connection.
Before use, confirm:
The drill accepts a 1-1/4"-7 threaded bit.
The drill is rated for a 9-inch core bit.
The equipment can operate the bit at the appropriate speed.
The machine is suitable for wet coring.
The application and material are within the bit's intended capabilities.
