Eagle Cutting Tool CDW-8750-1-1/4-7 Wet Core Drill Bit

Product Description

The EAGLE CUTTING TOOL CDW-8750-1-1/4-7 is a wet core drill bit designed for cutting clean, precise holes through masonry, concrete, and similar hard materials. The bit measures 7/8 inches in diameter and features a 1-1/4-7 threaded arbor connection for secure mounting to compatible core drill rigs. Wet core drilling relies on a continuous water feed to cool the diamond segment, extend bit life, and control dust. This bit is suited for plumbers, HVAC mechanics, and electricians who need to core through concrete walls, slabs, or block when running pipe, conduit, or duct penetrations.

This wet core drill bit is used in residential and commercial construction and service work wherever penetrations through concrete or masonry are required. Typical applications include sleeve installations for piping and conduit, anchor hole preparation, and utility rough-in work. The 1-1/4-7 thread is a standard arbor specification common to professional-grade core drill machines used across the plumbing, mechanical, and electrical trades.

Key Features

• 7/8 inch cutting diameter for standard pipe and conduit penetrations
• 1-1/4-7 threaded connection for direct mounting to compatible core drill rigs
• Wet cutting design requires water feed to cool bit and suppress concrete dust
• Suited for concrete, masonry, and block substrates
• Weighs 4.5 pounds for balanced handling on drill rig setups

Compatibility

Designed for use with core drill machines equipped with a standard 1-1/4-7 threaded spindle. Verify arbor thread specification on your drill rig before installation.

Installation Notes

Wet core drilling should be performed by a qualified tradesperson familiar with core drill equipment and applicable safety practices. Always ensure a continuous water supply is connected before beginning the cut to prevent premature diamond segment wear and to control silica dust per applicable OSHA guidelines. Secure the core drill rig firmly to the work surface before operation and confirm the work area behind the penetration is clear of electrical conductors, pipe, or structural elements prior to drilling.
