Diamond Drill Bit Adapter Dedra H1224 — SDS shank adapter for diamond core and drill bits

The Dedra H1224 diamond drill bit adapter is an SDS-shank conversion accessory designed to allow SDS-compatible rotary hammers to accept diamond core bits and other drill bits with non-SDS fittings. It provides a simple mechanical connection between an SDS tool holder and diamond tooling, enabling the use of diamond core bits for masonry, concrete and tile drilling without replacing the rotary hammer. The adapter is intended for applications where the user needs to couple high-performance diamond bits to SDS rotary hammers for wet or dry drilling tasks.

Advantages

The adapter offers quick and secure mounting to SDS tool chucks, maintaining stable bit retention during rotary hammer operation. Its design facilitates easy conversion of SDS-fit tools to accept a wider range of diamond cores and conventional drill bits with non-SDS shanks, reducing the need for multiple machines. Using the adapter helps preserve the rotary hammer’s functionality while expanding its compatibility with diamond tooling for demanding drilling tasks in masonry and concrete.

Suitable for

• Drilling with diamond core bits in concrete and reinforced concrete
• Masonry and brick drilling where diamond tooling is required
• Tile and ceramic hole cutting using diamond bits
• Situations that require converting an SDS rotary hammer to accept non‑SDS drill fittings

Key specifications

• SDS shank type for compatibility with SDS rotary hammers
• Converter design to accept diamond core bits and non‑SDS drill fittings
• Robust metal construction suitable for rotary hammer loads
• Secure retention mechanism for stable drilling operation

How to use

Insert the SDS shank of the adapter into the rotary hammer’s chuck until it locks in place according to the tool manufacturer’s instructions. Fit the diamond core bit or other compatible drill bit into the adapter’s receiving end and secure it according to the adapter’s retention method. Confirm the assembly is tightly seated and test at low speed or with light pressure to verify correct engagement before full‑force drilling. Observe the recommended drilling method for diamond tooling, including appropriate feed pressure and cooling if required.

Usage recommendations

Use the adapter with compatible SDS rotary hammers and diamond core bits rated for the material you are drilling. For extended bit life and optimal performance, use water cooling where applicable and avoid excessive axial force. Inspect the adapter and connected tooling regularly for wear or damage and follow the safety instructions of both the rotary hammer and diamond bit manufacturer.
