VEVOR Core Drill Bit, 3 inch Diameter, 14 inch Drilling Depth, 1-1/4 in-7 Internal Thread, High-Precision Welding Technology, Wet Diamond Core Bit for Reinforced Concrete, Red Bricks, and Masonry

VEVOR 3-inch wet diamond core drilling bit

A wet diamond core bit makes circular openings in masonry and reinforced concrete without using a percussion drill. Its three-inch bore and 14-inch drilling depth are particularly relevant to pipe penetrations and service openings.

How this version works

The manufacturer specifies a 3-inch (76 mm) core diameter, a 14-inch maximum drilling depth and a 1-1/4 in-7 female connection. This bit is designed for wet coring in suitable masonry and reinforced concrete, with laser-welded cutting segments. Water is part of the intended drilling process, not an optional substitute for dry work.

Choosing it for the right job

Confirm that the drill or rig accepts the threaded connection and has suitable capacity for the substrate. A nominal three-inch core is not the same thing as a finished clearance after allowing for a pipe sleeve. Check the 1-1/4 in-7 connection, drill capacity, reinforcement and safe water management before starting.

Setup and ongoing use

Keep the water supply controlled near electrical equipment, inspect cutting segments and follow drill manufacturer guidance on feed pressure and reinforcement. Use the correct feed pressure and keep the bit cooled as directed; inspect segments between holes.
