Hornady COAL cases, drill bit and tap

[Dennis]

Ok, I know I have seen it before but can't find it!

What size tap and what size drill bit do I need to make my own cases to fit my Hornady COAL tool?

Thanks,

Dennis

If I am not mistaken I believe the thread size is 5/16 X 36 thread

[Balljoint]

Yes 5/16 X 36 and use a 19/64 drill bit to drill out the primer

This info could stand to be a sticky note.

Where do I have to look to find a 5/16 36? I see a lot of 32, but no 36.

I had to buy a set of three, that's three drill bit's and three taps from a specialty company. I looked and ask people for a week before I found them!

If you want a set, set me know. Their brand new with the plastic coating still on them. I could let a set go for $25.00, inc shipping.

They are very hard to get, but I just finished cutting one of my 338 edge case and it works perfectly with the Hornady/Stoney tool!

I see them in Enco catalog $12.95, Online @ use-enco.com

Where were you last month?

Last month i was having major surgery, Now just siting around.

I have a couple extra set! I may part with them, I over nighted them, plus ordered them from a speciality warehouse! NONE were in the state of Louisiana. I might be able to part with two of he sets (drill bit, and tap), up front, I will ship them to the lower 48 for $30.00 a set!

If the demand is there, I would order a big lot of them if there were enough people intersted in them! Maybe they would be a litte cheaper!

I bought my tap from Victor for $8.50.

Their shipping is a bit high for single items but I had other stuff to buy at the same time.

I think that's where they got me, but I have my drill and tap! They work!!!!!

Just talked to enco, they don't sell the 5/16X36. Victor sells em for a good price, but you have to order $25 worth of items plus shipping before you can order from them.

I know this thread is old, but I have a question: what did you guys use to hold the case steady without damaging it while you drilled out the primer pocket? I have tried this without much success using vice grips, a bench vise, my hand, etc.

[geargrinder]

I used the 3-jaw in my lathe.

[Dennis]

I use a 2x4 split down the middle, I then drill a hole in the middle of the seam the size of the brass, put it in a vise and drill. Usually there is enough tension to drill with no issues, if it doesn't hold the brass, then cut another hole one size smaller.

Good info.

Here you go. JTS Machinery & Supply Co. tel. 800-321-3566
Catalog # 1-372-150 5/16-36 tap, $7.32 each. no min order.
I do not recall shipping cost but it was reasonable.

For those of us that don't have a $20,000 lathe, put the case in a hammer bullet puller and then put that into a vice. Enco dose have the tap, #891-4932 on page 89 at $14+. I uses a ElChepo Harbor Freight table top drill press ($40 in 1985?) like the one that T/C used to chamber Contender barrels.
