SDS Max to 1 1/4" UNC adapter
This adapter is ideal for drill bits with a 1 1/4" UNC thread for larger holes when used with a heavy-duty hammer drill or combi hammer with an SDS-Max chuck: SDS Max to 1 1/4" UNC external thread, machined from a single piece. For back box cutters and core bits with an M16 thread, we offer our SDS Max to M16 adapter.
Thread and chuck
The adapter is inserted into the hammer’s SDS-Max chuck and locks into place; the core bit is then screwed onto the UNC thread at the front. As the adapter is machined from a single piece, there is no joint between the chuck and the thread that could come loose, and therefore no ejector wedge is required.
- Machine side: SDS Max
- Tool side: 1 1/4" external UNC
- Design: manufactured in one piece, without an ejector wedge
- Material: powder-coated steel
- Length: 200 mm
Compatible core bits and tools
The diamond tool runs on a hammer drill in pure drilling mode without percussion. Our 1 1/4" UNC dry diamond core bits with a working length of 400 mm, available in 20 diameters ranging from Ø 32 to 202 mm, are compatible with the UNC thread and are suitable for concrete, masonry, brick, lightweight concrete and concrete blocks. For thick walls, our 1 1/4" UNC extension adds 100, 250 or 500 mm.
You can find all other adaptors in our core bit accessories range.
