I recently purchased some hex power bits from grainger (www.grainger.com) to replace the ghetto rigs I had set up for my hex bits (1/4" to 3/8" shack adapter to hex socket heads). Anyone using this setup knows it will get annoying because the socket head will frequently come off the adapter (even with tape attaching the two). It's kinda hard to find, but there does exist straight up 1/4" drive to 5/16" hex and 1/4" drive to 7/32"

Here're the ones I got from grainger (they're cheap too...about 2 buckets per bit)

Just search 5/16" or 7/32" hex power bit

Nice! We use these at the Spot cause they have 'em at our local hardware store, but even the store employees don't know they have 'em--we have to seek them out ourselves. Funny how something so obviously useful can be so hard to find.

Sorry to sound dumb but...

I was on the grainger site had a hard time finding the correct part. Do you think you could post the exact page for the hex drives?

thanks

I can't find them on Grainger either, but the item #s on McMaster are:

8526A85
and
8526A83

Those are for the 5/16 shank 1 and 5/16" long bits. They make 1 inch ones with 1/4 shanks as well.

syedhali - Was your 1/4 to 3/8 shank adapter impact ready? I haven't had any problems will my sockets with 7/32 and 5/16 hex heads coming off the shank adapter even without tape. The metal balls locks them on nice and tight.

I just searched:

-5/16" power hex bit (should be the 8th search result)
-7/32" power hex bit (should be the 5th search result)

...for each bit on grainger but McMaster works too

I definitely had a problem with the two coming apart in the larger, older holds that use smaller bolts but still have a long bolt tunnel. When I'd pull the two pieces out the hold the socket portion would always come off the adapter...but perhaps that's because my socket adapters weren't the greatest :/ Either way, I've been using these new bits and they're too sickkkk :)

Ancient thread bump...

I recently got myself a set of these bits through Granger. To save anyone else the hassle of trying to find the part numbers for these things, here they are:

3UNE8 (5/16")
3UND9 (7/32")

When I went to my local Grainger store here in Houston we couldn't find them in their system or catalog at all. I had to find them on the website and go back to the store with the part numbers. Turns out they are a special order item and they had to bring them in from out of state.

If you either don't live near a Grainger store - or don't want to hassle with going down to it and searching around - or don't want to have to pay $10 in S&H, we carry them on our site: http://www.elementclimbing.com.

Buy $75 worth of holds from us and mention this post at checkout, and we'll give you one for free.

Happy Setting / Happy Climbing
