Intertap shank opening

[ggriffi]

Shank measures just under 7/8". Do I want any wiggle room i.e. 1" or leave it snug like it will be with 7/8"

If your 7/8" hole is exactly where you want it, then that's it. The only reason to go oversize would be to correct for a mis-drilled hole.

I did mine 7/8" and the fit is tight. I didn't want any wiggle room.

Thanks. I didn't want to buy two bits to have to take back one

 

[ancientmariner52]

What kind of bit, and what material are you drilling?

My guess is OP is drilling wood and using a spade or forstner bit. But to the question. Installed same shanks and use a 7/8 bit.

Yeah, I was hoping to guide him toward an economical bit choice, but for all I know he might sell 'em for a living. Just assumed that if he didn't know about hole clearances, he might be in unknown territory.

i used 7/8" as well for the same shanks and worked great. just make sure you drill it straight!

2x8 pine. Planned on using a spade bit with my drill

Sounds good. Clamp a backing board to it and it won't look like a cannonball hit it when you break through.

Very much yes, clamp a waste piece behind it. I used a spade bit and it can really tear through the back.

I have a 2x4 just for that

Good advise if one isn't able to drill from both sides...

Cheers!

With a bit and brace I'd do just that. Oops, wrong hobby.

I used a spade bit and no issues. Drilled a good tight hole .
