[QUOTE="ProDave, post: 510749, member: 6969"] What are these "ECO Joists" you talk of? You need to be VERY careful here. Some "Engineered" Joists have strict limits where and how big you can drill them. And If these are I beams, with OSB type material forming a web with more solid bits of wood at the top and bottom, then you should never drill the top and bottom members under any circumstances only the OSB web and only in prescribed locations. If these are metal web Posi Joists you should again never ever drill the top and bottom solid timber members. But of course you also know if drilling plain ordinary timber joists there are prescribed zones where you can and cannot drill holes. If your difficulty is using auger bits then they won't work well as there is not enough meat for the screw tread pilot to grip and pull the drill through. Instead use flat bits. [/QUOTE]
