## Long description

GRAPHITE hex adapter for diamond hole saws 57H880 is a connection accessory that allows diamond coronas to be mounted on standard power drills. The adapter features a hexagonal shank to fit drill chucks and quick-change chucks, providing a stable mechanical connection for drilling holes in hard building materials. It is intended to transfer torque reliably from the drill to the diamond hole saw when cutting through concrete, masonry and natural stone.
Advantages
The adapter offers a robust hex shank design that reduces slippage in chucks and supports secure engagement with quick-change systems. Its compact construction facilitates easy installation and removal of diamond hole saws, while maintaining concentricity for accurate hole cutting. The part is compatible with common power drills and is engineered for repeated use in workshop and construction environments.
Suitable for
Drilling circular openings in concrete and reinforced concrete (with appropriate coolant/wet cutting).
Cutting holes in masonry, brick and block walls for plumbing or electrical installation.
Processing natural stone and ceramic materials where diamond hole saws are required.
Use in hand-held drilling operations and drill-press setups that accept hex shanks.
Key specifications
Connection type: hexagonal shank compatible with standard chucks and quick-change holders.
Primary use: adapter for diamond hole saws (diamond coronas) to be driven by power drills.
Material properties: engineered for torsional strength and wear resistance suitable for drilling loads.
Typical applications: construction and workshop hole cutting in hard materials such as concrete, masonry and stone.
How to use
Fit the hex shank of the adapter into the drill chuck or quick-change holder and tighten securely according to the drill manufacturer’s instructions. Attach the diamond hole saw to the adapter’s connection end, ensuring correct seating and firm engagement before starting the drill. When drilling, use appropriate feed pressure, rotation speed and cooling method recommended for the specific diamond hole saw and the material being cut. Monitor the connection periodically during prolonged use to confirm the adapter remains tight and concentric.
Usage recommendations
When drilling concrete and masonry, use water cooling or intermittent cutting to reduce heat and extend the life of the diamond hole saw and adapter. Select drill speeds and feed rates matched to the diameter and type of diamond corona, and always follow safety practices including eye protection and secure workpiece clamping.
