Drill bits for homemade PCBs?

[Supercap2F]

Well the drill bit's came in over the weekend, so I decided to have another go with the drill press and it turned out okay.

I found out that the lower I have to pull the spindle down the more play it has in it. Before I made the mistake of having the board about two inches away - Opps!

This time I moved the board so it was almost touching the bit when the spindle was in it's all-the-way-up position, and I was able to drill it without any trouble (drill bit's snapping that is). I also bumped up the RPMs on the drill press by changing the drive belt position (from about 700 to 1300).

Thanks a ton for all the advice guys! You've all been quite helpful!

If you have a Horror Freight close by you can purchase some cheap backups. When these break you won't cry so much!

Martin, you never cease to entertain me. For those that think that humor is the only thing you post... Not true! Occasionally you squeeeeze in a post, here and there, containing technical data!

I like you!

Lol, like the above technical data?
Forums are not just serious sites for geeks!! You have to have a little light hearted side too.
But sometimes I cannot help myself!!

FWIW, I like you too uncle Chris

I like everybody on here. It's the best forum for me to learn. Everybody is so friendly and helpful.

I must admit this Forum is the best. I have been on many and the banter on this site is top notch. But when we mean it we get right to it. I do miss the bushy beard Chris of your old Avatar.

Sorry mates, the beard ain't gone but that old bugger has morphed. The beard is now kept close trimmed to match my trim weight of 170lbs,.. down from 165lbs when that head shot was taken. I played Santa Clause that year for my great nieces & nephews.

The "setup" I would use, is my Dremel rotary tool and the drill press made for it. Very slight pressure. Bits I use are purchased at a hobby/craft store like Hobby Lobby or Michael's. The Dremel is the "power tool" that I use most often. There are other "attachments" for it, like the router, and others. Also used with a wire brush to clean up messy solder joints. The sanding disc can be used to sharpen small drill bits.

That's not good advice. If a joint is messy suck up or wick up the joint and then re-solder it.

Martin, I don't think there's any word, phrase or sentence that you couldn't find some humor in.

That's the French spelling. You guys need to close up that damn tunnel!

Ok, mummy taught me Frenchly...
Given the option, I would allow them all in!!
Then mid way!!!
M134 Minigun=
Place of origin= United States Cartridge= 7.62x51mm NATO
Rate of fire= 2,000 - 6,000 rpm Muzzle velocity= 2,800 ft/s (853 m/s)

But one can hope and dream.....

OUCH! Nice but I've always had the hots for the "Classic" and iconic M2 Browning .50Cal. A single round is a real attention getter! Considering how old she is it's amazing that she still holds her own in the realm of serious impact power.

I grew up with the Vulcan M61A! 20mm Gatling Gun while serving with the U.S. Air Force, but it is a bit of a load to carry around. Mine were carried by B-52H bombers. The 30mm GAU-8 Avenger packs a bigger wallop, mounted in a A10 close air-support platform, but depleted uranium rounds may be hard to come by. For everyday social work it is hard to beat my Colt .45 ACP M1911 semi-automatic pistol, although some will swear by the Israeli .50 caliber Desert Eagle... well, at least until they actually shoot it, after which they may swear at it.

It is expensive to own full-automatic weapons in the USA since there is a $200 tax stamp required each time they are sold. However, there is a shooting range nearby in Kentucky that will rent you full-auto weapons (for use on their range) and sell you the ammo to fire them. A friend, who has already been there, wants me to go with him some weekend, but I doubt I can afford the experience. The two indoor gun ranges I belong to don't allow shooting re-loaded cartridges, so even shooting the Colt is at least a $50 adventure. Can't imagine what it costs to fire off a couple thousand rounds with the M134. However, for serious long-range social work, it is hard to beat the M107 .50 caliber sniper rifle, provided it is equipped with the proper optics and the shooter knows how to use it. I do like the M2 Browning, and it is nice for field work, but it is also very expensive to shoot.

Have we wandered off-topic on drill bits yet?

Just a little...
But it's far more satisfactory making holes with a bang!!
