SDS drill extension bar

[RobinClay]

I need to drill a neat 75mm dia hole horizontally through about 600mm of old brickwork; it's only accessible from one side.

I've got an SDS drill and a 75mm dia core drill - but that will only go in about 150mm.

Is there such a thing as an extension bar with SDS type "clutch" on one end, and the standard SDS "male" the other end, to insert between the core bit and the drill itself ? If so, from where can I get one ? (And how much?)

You can get the male/female arbour extensions but generally much smaller than what you require, either purchase the above arbour or you may need to marry two extensions arbours together, the above option would be cheaper.

Thank you ! I didn't know the word "arbour" applied to this.

Happy to help, I had a similar problem coring out a very thick yorkshire stone wall, a few years back. Needed either a longer arbour shaft or an extension bar, I managed to find an extension bar at 300mm, which did the job great, but cannot for the life in me remember where from. I did come across many at 150mm and 200mm but needed a little bit more, and got lucky I guess. Still got it in the kit.

I know the feeling !

I've ordered "one o' they" - though to me, an arbour is a place to sit in the garden !

Up until my teens I thought it a place where seaworthy vessels were to found.
