Milwaukee 4″ Diamond Wet Core Bit

DOMINATING REINFORCED CONCRETE WITH PRECISION CORE DRILLING

When you’re pulling cores on a structural deck or running conduit through cured footings, you need a bit that doesn’t choke when it hits light rebar or mesh. This 4-inch diamond wet core bit is engineered for the high-torque demands of heavy-duty coring rigs, ensuring clean, fast penetrations without the segment loss common in inferior bits. The 15-inch drilling depth provides the reach needed for standard slabs and walls, while the wet-use design keeps the diamonds cool and the slurry moving, maximizing the life of the bit in high-production environments.

• / 1-1/4″-7 Threaded Hub ensures a rock-solid connection to high-capacity core rigs like the MX FUEL™ Core Drill.
• / 15″ Drilling Depth allows for full-depth penetration through standard structural slabs and reinforced walls.
• / Engineered Diamond Segments optimized for fast cutting in cured concrete with small diameter rebar and steel mesh.
• / Wet-Use Optimization reduces heat friction and manages silica dust for a cleaner, safer jobsite.
