Frequently asked questions

What thread does the 460mm extension bar use?

It has a ½" BSP female to ½" BSP male threaded fitment, different from the 1¼" UNC connection used on our other Mexco extension bars.

How is this bar meant to be fitted?

It screws directly between your diamond core drill and a core drill adaptor, rather than fitting straight onto a core bit.

How much extra reach does it give me?

The bar itself is 460mm long, adding that much reach for drilling through cavity walls and deep masonry sections.

Will it work with my core drill adaptor?

Any adaptor with a matching ½" BSP female thread will fit. Check your adaptor's fitting before ordering if you're not sure.

Does the extension affect drilling accuracy?

No. The threaded BSP connection is designed to hold a firm joint so power transfer and control are maintained across the extended length.

Who typically uses this extension bar?

Plumbers, electricians and builders use it for cavity wall and masonry drilling where a standard core drill setup can't reach.
