Hole diameter for 10M Canadain metric bar

Hole diameter for 10M Canadain metric bar

(OP)
Where can I find the recommended hole diameter for Canadian metric 10M bar in concrete anchored with adhesive? I don't see this given in Hilti catalogue. I would guess that it should be 14 mm diameter but am not sure. I know that too large a diameter hole reduces the strength of the connection.

RE: Hole diameter for 10M Canadain metric bar

In their Hit-HY200 catalogue it notes for a 10m bar you need a 9/16"=14.3mm drill bit. So I guess you'd be right on.. either way it will be drilled with a 9/16" bit as I don't see many metric drill bits up here.

RE: Hole diameter for 10M Canadain metric bar

They don't have metric bits in Canada?!? interesting.

RE: Hole diameter for 10M Canadain metric bar

They're certainly available, but they aren't as common. We typically use imperial fasteners for most construction tasks, so the holes are generally imperial as well.
