The Clipacore DuoCut Pro Adaptor enables accurate enlargement of existing core holes to a wide variety of diameters for a wide variety of applications, including: upgrading boiler flues / gas pipes / waste pipes / soil pipes / extractor fans / condense pipes.

Simply clip the Duocut Pro into a Core Adaptor attached to a core bit of the same size as the existing hole. Then, insert the A-Taper side of the adaptor, just as you would a Guide Pin or Pilot Drill, into the desired core bit (larger), ensuring precise alignment. Made from high-quality Cr40 Chrome Steel, it offers exceptional shear strength and is specially heat-treated for enhanced durability and toughness.
