Eagle Cutting Tool CDW-7500-1-1/4-7 Wet Core Drill Bit

Product Description

The EAGLE CUTTING TOOL CDW-7500-1-1/4-7 is a wet core drill bit designed for cutting precise circular holes through masonry, concrete, and similar hard construction materials. The bit features a 1-1/4-7 threaded connection for secure mounting to compatible core drill rigs and drives. At 3/4 inch in diameter, it is suited for smaller-bore penetrations common in plumbing rough-in, HVAC sleeve installation, and electrical conduit pathways. Wet drilling operation keeps the bit cool, reduces dust, and extends cutting life. This tool is installed by licensed trade professionals working in new construction and retrofit applications.

This wet core drill bit is used in residential and light commercial construction wherever a clean, controlled bore through concrete block, poured concrete, or masonry is required. Typical applications include plumbing penetrations for pipe sleeves, HVAC line set or duct sleeve openings, and electrical conduit entry points. The 3/4 inch bore diameter is a common size for smaller service penetrations, and the 1-1/4-7 thread mount is a standard connection found on many professional-grade core drill motors and rigs.

Key Features

• 3/4 inch cutting diameter for small-bore masonry and concrete penetrations
• 1-1/4-7 threaded arbor connection for compatibility with standard core drill motors
• Wet operation design reduces heat buildup and extends bit service life
• Produces clean, accurate holes suited for pipe, conduit, and sleeve installations
• Minimum order quantity of 1 unit

Compatibility

Designed for use with core drill motors and rigs equipped with a 1-1/4-7 threaded spindle connection, which is a widely used standard thread on professional wet core drilling equipment.

Installation Notes

Wet core drilling should be performed by qualified trade professionals familiar with concrete cutting tools and jobsite water management. Ensure the core drill motor is powered off and locked out before mounting or removing the bit. Adequate water flow must be maintained throughout drilling to cool the bit and suppress concrete dust in accordance with applicable OSHA silica dust control requirements. Always secure the drill rig to the work surface and verify the bore location does not conflict with embedded rebar, post-tension cables, conduit, or other structural elements before drilling.
