Frequently asked questions

What fitting does the extension bar use?
It has a 1¼" UNC male thread on one end and a 1¼" UNC female thread on the other, so it fits directly between a diamond core drill and a compatible 1¼" UNC core bit.

How much extra reach does it add?
The bar itself is 150mm long, giving you 150mm of extra reach for deep or cavity wall drilling.

Will it fit my core drill bit?
Any diamond core bit with a 1¼" UNC connection will thread onto this extension bar - check your bit's fitting before ordering if you're unsure.

Does it affect drilling accuracy?
No. The threaded connection is designed to stay secure under load, so power transfer and accuracy are maintained through the extension.

Is this suitable for wet core drilling?
Yes, it's designed for use with wet diamond core drilling equipment for masonry and construction work.

Can it be used with more than one extension bar?
The female thread allows another compatible 1¼" UNC accessory to be fitted, though check total reach and rigidity for your specific application.
