## Long description

The Delphi Tools Diamond Core Bit 1 1/4" (152/430 mm) is a wet-core drilling accessory designed for making large-diameter holes in concrete, reinforced concrete and masonry. With an outer diameter of 152 mm and a cutting length of 430 mm, the bit uses diamond cutting segments to provide efficient material removal and extended service life when used with a compatible core drilling rig and cooling water supply.
Advantages
The diamond segments ensure consistent cutting performance and resistance to abrasion, while the steel body provides rigidity and accurate hole guidance. Wet drilling reduces dust and cools the segments, which helps preserve cutting geometry and prolongs usable life. The bit is manufactured for professional construction and renovation tasks where reliable, repeatable large-diameter cores are required.
Suitable for
 Drilling large-diameter holes in concrete and reinforced concrete
 Creating openings for plumbing, HVAC and electrical installations
 Core sampling and removal of structural sections in renovation work
 Masonry drilling in brick and block walls
Key specifications
 Outer diameter: 152 mm
 Overall cutting length: 430 mm
 Cutting material: diamond segments
 Operation mode: wet drilling (requires water cooling)
 Intended materials: concrete, reinforced concrete, masonry
How to use
Fit the core bit to a compatible core drilling rig following the rig manufacturer's mounting instructions and ensure the connection is secure. Position the rig and center the bit on the marked drilling point. Start water flow to provide continuous cooling and dust suppression before engaging the drill. Apply steady, even pressure and allow the diamond segments to cut at their natural rate; avoid excessive force that could cause binding or damage. Retract the bit periodically to remove slurry and inspect progress. After completing the hole, stop water flow, remove the bit from the arbor and clean slurry from the segments and body.
Usage recommendations
Use with appropriate core drilling rigs rated for large-diameter wet core bits and ensure continuous water supply for cooling. Select drill speed and feed rate according to material hardness and follow all safety guidance for PPE, dust and slurry management. Inspect the diamond segments regularly and replace the bit if segments are worn or damaged to maintain cutting performance and safety.
