I’m in limbo for a few days until I get the right drill bit. Meanwhile, I bought a benchtop drill press from harbor freight…not too bad for the price $67.
It beats using a pistol drill. On some of the really cheap drill presses the table flexes when you push down on them so consider putting a piece of wood under it or something to beef it up some. But even at its worst I bet it’ll drill a lot more square than folks can by hand. This is my drill press http://i.imgur.com/jXSFT.jpg She’ll poke a hole in solid steel a couple inches in diameter. I bought it off Harbor Freight too.
Not sure where you’re located but if you have a fastenal near by. They generally carry some more machining special drill bits in stock. Just a thought. Let us know how that drill works out for you.
@Chaotic_Logic hey thanks, there’s one nearby. Since my ordered bit is due in tomorrow I’ll wait, but that’s an excellent resource! I almost tried grainger & he supply, but I decided I could wait. The ones I tried would have had to order it anyway, fastenal had a countersink that size in stock, but not the counterbore. I’m sure they had the simple drill bit available
@George_Allen I have a collection of tiny counterbore bits but for bigger ones I just use end mills. I don’t do a whole lot of counterboring anyways. I suppose if I was really desperate I could do a custom grind on the right size twist drill too? I’ve done that for chain drilling, and stuff like that.
I’m just going to use the 13/16” bit to drill most of the hole and I may try to use the counterbore to finish it, if possible. If not, I’ll just use the bit for the whole thing.
The counterbore is just an endmill. There is no pilot hole.
@George_Allen Do you mean a reamer? Counterbores and reamers are different things. Real counterbore bits have a pilot bearing too.
This is listed as a counterbore by 80/20. That made it a little confusing ordering a comparison
I just posted the photo in the catalog on here.
@George_Allen they sure look like two flute Weldon shank end mills to me. Now something like this is a counterbore https://static-content.cromwell.co.uk/images/854_854/g/jeeps/021/ken0213660k.jpg
What a pain in the neck!missing/deleted image from Google+
I was practicing before the bit came in missing/deleted image from Google+
@George_Allen practicing unfamiliar methods is always a good idea.
