Frequently asked questions

What does this adaptor convert between?

It joins a 1¼" UNC male thread to a ½" BSP male thread, so core drilling equipment with different thread standards can be connected together.

Is this a male-to-male fitting?

Yes. Both ends have external (male) threads - it is designed to sit between two components that each have an internal (female) thread, such as a core drill machine and an extension bar.

Will this fit my core drill machine?

It will fit any machine or fitting with a matching 1¼" UNC or ½" BSP female thread. Check your machine's thread size before ordering, as core drill fitments vary between manufacturers.

Can I use this for wet core drilling?

Yes, it is suited to both wet and dry diamond core drilling setups.

How do I fit the adaptor?

Thread it onto the matching female fitting on your machine or extension bar and tighten using a spanner on the hex body.

Is it suitable for daily professional use?

Yes, it is built for regular use on professional masonry core drilling work.
