Core bit segment fitting and welding service

When your bit’s teeth wear out, you don’t need a new bit: we fit new segments with specialised equipment backed by experience since 2005, and we test and trim your bit free of charge before fitting. See segment types and prices, plus CNC extension rods for drilling to great depths with the same bit.

How to choose your core bit size

• The bit size is the hole diameter; in core drilling, one inch = 25.4 mm.
• 14 to 46 mm for rebar anchoring and fixings, 2 to 7 inch for gas, plumbing and HVAC pipes, and 8 to 20 inch for drainage, ventilation and large openings.
• Make sure the size is within your machine’s capacity: an 8 inch machine runs bits up to 8 inch, and so on.
