The Clipacore Range helps installers save time and stay safe while also protecting their tools. Our Quick Release System allows you to swiftly and easily remove a Core Drill Bit. A Drill Adapter attaches to a Core Adaptor with a specially designed clip that can be released by hand, making it simple to dismantle the system after drilling out the core. We also offer two solutions for enlarging existing holes. Duocut Pro is perfect for enlarging condense pipes, gas pipes, waste pipes, and boiler flues. Condensate Pro has been designed to uniformly upgrade existing overflow pipes up to 32mm (1.24").
