Frequently Asked Questions

Why is water required during drilling?

Water cools the cutting area and helps remove slurry. Maintain a continuous water supply during operation.

Can it drill through steel reinforcement?

No. This specification is intended for concrete, brick, block and masonry without steel reinforcement. Choose a dedicated reinforced-concrete core bit when rebar is present.

Which thread should I order?

Check the spindle connection of your drilling machine. Available options include M16, M22, 1-1/4″ UNC and 1/2″ BSP.

Can the effective length be customized?

Yes. The standard effective length is 450 mm, while other lengths can be produced upon request.
