Eagle Cutting Tool CDW-55000-1-1/4-7 Wet Core Drill 5.5in

Product Description

The EAGLE CUTTING TOOL CDW-55000-1-1/4-7 is a wet core drill bit designed for cutting precise circular holes through concrete, masonry, and similar hard materials. Wet core drilling uses water as a coolant and slurry flush, which extends bit life and reduces airborne dust during the cut. At 5.5 inches in diameter, this bit is sized for larger-diameter penetrations common in mechanical, plumbing, and electrical rough-in work. It weighs 12.2 pounds, indicating a heavy-duty segment construction suited for production drilling applications.

This wet core drill bit is used in residential and commercial construction and renovation projects where large-diameter core holes are required. Typical applications include running pipe sleeves, conduit, ductwork penetrations, and drain lines through poured concrete floors, foundation walls, and concrete block. It is installed and operated by plumbers, HVAC technicians, and electricians who require clean, accurate penetrations without jackhammering or rough chipping.

Key Features

• 5.5-inch cutting diameter for large-bore penetrations through concrete and masonry
• Wet-cutting design uses water coolant to manage heat and extend segment life
• Heavy construction at 12.2 pounds supports sustained production drilling
• Sized for mechanical, plumbing, and electrical rough-in penetration work

Compatibility

Designed as an OEM-style replacement or standard wet core drill bit for use with compatible core drill rigs and drive systems accepting a 1-1/4-7 threaded connection.

Installation Notes

Wet core drill bits should be installed by qualified tradespeople familiar with core drill rig operation and masonry drilling procedures. Confirm the drill rig spindle thread matches the 1-1/4-7 thread specification before mounting. Always establish a continuous water feed to the bit before beginning the cut, and never run the bit dry. Follow applicable OSHA and site safety requirements for concrete cutting, including slurry containment and operator eye and hand protection.
