40mm Amtech F1209 Core drill bit, is there a 300mm or longer extension to fit this drill bit?
Cha from London
Hi Cha, we offer an Amtech 350mm SDS extension bar – F1205, this should be adequate for your requirements. However an alternative is the Amtech 300mm extension complete with 2 core drills under – F1195. You should use a powerful 1500W or similar SDS drill with the side handle fitted for safety.
