Adapter for core drill to SDS+ shank Högert Technik HT6D470

Adapter for core drill to SDS+ shank Högert Technik HT6D470 is an accessory that converts SDS+ rotary hammer chucks to accept hollow-core (coring) drill bits. Designed to allow installers, electricians and plumbers to perform larger diameter drilling in masonry, concrete and similar substrates using SDS+ tool systems, this adapter bridges the compatibility gap between SDS+ rotary hammers and standard core-drill arbors.

Advantages

The adapter provides a secure mechanical connection between an SDS+ shank and a core drill arbor, enabling stable rotation and efficient removal of material when using hollow-core bits. It is compact and simple to attach and detach, reducing downtime during tool changes. The construction is intended to withstand the torque and hammering action typical of masonry drilling with SDS+ machines, offering consistent performance when used within recommended operating conditions.

Suitable for

• Drilling larger-diameter holes in concrete, brick and block using core drill bits with an SDS+ rotary hammer
• Electrical, plumbing and HVAC installations requiring precise openings for pipes, conduits and cable runs
• Construction and renovation tasks where a coring arbor must be used with SDS+ tools

When it may not be suitable

This adapter is intended specifically to adapt SDS+ shanks to core drill arbors and is not a substitute for purpose-built core-drilling rigs or water-cooled coring systems. It may not be suitable for continuous heavy industrial coring where specialized machines, cooling, or vacuum mounting systems are required. Users should ensure the selected core bit diameter and type are compatible with the mechanical limits of their SDS+ machine and with the adapter's intended use.

Key specifications

• Compatibility: SDS+ rotary hammer shank to core drill arbor conversion
• Application: Use with hollow-core/coring drill bits for masonry and concrete
• Material: metal construction suitable for torque transfer (manufacturer-specified materials)
• Operation: For rotary and hammer-drill action typical of SDS+ tools (use with recommended drill modes)

How to use

Fit the adapter into the SDS+ chuck or directly into the SDS+ tool according to the tool manufacturer’s instructions, then secure the core drill arbor or coring bit on the adapter as required. Confirm that the connection is locked and the assembly rotates freely without excessive play before starting. Select an appropriate drill mode and speed for the substrate and the core bit, and use progressive feed pressure while maintaining alignment. For dry coring, control dust and for wet coring use appropriate water supply and splash protection as needed. Always follow safety guidelines for personal protective equipment and tool operation.

What to consider before purchase

• Verify that your SDS+ rotary hammer supports the torque and speed required for the planned core bit sizes
• Confirm the core bit arbor style and diameter are compatible with the adapter’s arbor end
• Consider whether wet coring, vacuum mounting or dedicated core-drilling equipment is more appropriate for heavy or continuous work
• Check tool manufacturer recommendations and safety limits for hammer action and duty cycles

Usage recommendations

Use in intermittent coring tasks with appropriate core bits and ensure cooling or dust control measures are in place. Inspect the adapter and connections before each use and avoid exceeding the recommended workload for your SDS+ machine to maintain safety and prolong the service life of the accessory.
