BRSCHNITT Core Drill Bit Adapter, 5/8"-11

The 5/8"-11 male thread and SDS-Plus shank let this steel adapter pair bridge a compatible core bit arbor and an SDS-Plus tool. It is intended for a 5/8"-11 female arbor, so the key buying check is whether that thread matches the accessory you already own. The listing gives a total length of 72 mm and a 45 mm shank, useful details when comparing it with the space and reach your setup allows. One caution stands out: it also says not to use the adapter on “Hammer Model,” without identifying which models that warning covers.

Technical details

This is a two-piece adapter set, made of steel. Each adapter has a 5/8"-11 male thread at one end and an SDS-Plus shank at the other. The stated total length is 72 mm, with a 45 mm shank. Its purpose is to let a tool or accessory with a 5/8"-11 female arbor connect to an SDS-Plus drill, it does not change the thread or shank standard of the parts you attach.

In practical terms, this could suit someone who already has a core drill bit with the specified female arbor and wants to use it with an SDS-Plus tool, rather than buying a separate accessory with a different connection. The adapter is a connection piece, not a core drill bit, so the cutting accessory and the drill still need to be suitable for the job.

Getting the most from it

Before fitting anything, match the adapter’s male thread to the accessory’s female arbor and make sure the other end is the SDS-Plus format your tool accepts. For example, if you are sorting out a core-drilling setup in a workshop, check the thread on the bit first, a similar-looking connection is not enough to establish compatibility. Seat the parts securely according to the instructions for your drill and accessory.

The product description names an SDS-Plus hammer drill as the intended tool, but separately warns against use on “Hammer Model.” Since it does not explain what that phrase refers to, don’t treat the adapter as suitable for every hammer drill or operating mode. Follow the instructions for the specific tool and bit combination.

Usage tips

Keep the adapter aligned while attaching the accessory, and avoid forcing the thread if it does not engage smoothly. The stated dimensions can help you judge whether its 45 mm shank and 72 mm overall length suit your setup, but the listing provides no additional clearance or performance information. This is a simple way to join two specified connection types, not a solution for an arbor with a different thread or a drill that uses another shank standard.

It’s a good option if you already have a 5/8"-11 female-arbor accessory and an SDS-Plus tool, and want to connect them with a purpose-made adapter. It may not be the best option if you need a different thread, need confirmation for a particular hammer model, or want a complete drilling accessory rather than the connector alone.

Before buying

Check both ends of your existing setup: the bit or arbor needs a 5/8"-11 female thread, and the drill needs to accept an SDS-Plus shank. The two-piece pack may be useful if you need a pair, but the listing does not describe any other included parts. Its steel construction and stated dimensions are clear, specific tool-model compatibility beyond the stated connection types is not.

Three specific questions

What does the threaded end fit? It is a 5/8"-11 male thread, intended for a compatible 5/8"-11 female arbor.

What does the other end connect to? The SDS-Plus shank is intended for an SDS-Plus tool.

Is it suitable for every hammer model? The listing says not to use it on “Hammer Model,” but does not identify the models covered. Treat that as an unresolved compatibility warning and follow your tool’s instructions.
