Default Best drill bits-metal

Okay folks, I'm tired of buying drill bits that break at the least bit of pressure. I need some bits that will drill through soft metal, drill out screw heads etc. So many of the former "name brand" bits are unadulterated crap* and I long ago learned the "cheap drill bit" lesson.
Thank ya'all.

*Crap: crummy, rotten awful product.

Warren,

I use plain old black oxide finished drill bits (from enco, McMaster, etc), nothing fancy. I don't use the Tin coated, because I don't notice much of a difference. Nothing fancy on the points, just something simple I can resharpen. I started with an index, but have bought ones I use alot like #7, F, etc. by packs of 5.

If you're snapping a lot of drill bits, you may not be lined up directly above your centerpunch, and sideloading the bit. Number drills especially don't handle this very well.

Warren, are they for a hand drill or for a drill press?
I use mainly Bosch bits, and they are not bad.

Hi Warren

You may want to pickup some subby drill bits they are very short and with a 135 deg.grind on them they are made just for drilling metal you can also try this little trick, put the drill bit all the way in the chuck and just have about 1/2" of the bit sticking out of the chuck,if it can't bend it will not break..the norm.

I have in the pass cut off the drill bits just for that type of job..
If you have a Drill Doctor you can make your own stubby set, quick and easy and for about 1/4 of the normal price.
Just cut off the point and than put on a new point, about a 2 min.job with the Drill Doctor.. i.e. 1/2" drill bit 2 1/4" long with a 1" long flute.


Drill Doctor and worth every dime,the lower price one (50.oo) will work just fine for most drill bits, the best money you can spend for your shop.

Ahhhh...yes. Thanks fellas. Some excellent ideas, especially the one about loading bit deeper in chuck. And I think I may very well have been off center yesterday and that broke one of the bits. The bits are being using in Makita and P-Cable LI drills (very niiccceee!). I had pretty much concluded that my last hope was Bosch. I already KNOW that some of the big name bits are useless.
I am not fanatically opposed to Chinese products: I have several radios and other devices that will knock your socks off-but I really DO dislike our big name companies selling out so totallly that they seem to have forgotten what quality control is all about. I have some nearly indestructible tools with a big M on them and they are great. But try their drill bits. I was always a fan of those yellow D drills and stuff too. But try their drill bits and some of their other stuff now. Oh sure-they'll send you a new one when it breaks! Why not; they're making ten times as much on the drill now as they were.

Hi Peter

I use the belt sander ( Balldor 2 HP ,2" x 48' belt) and I use the 40 to 320 grit belts..make most of my bits from jobber size bits.

Here's a snapshot of some of them,see below

I have made a few. Check out the boughten one, and try to duplicate it. I use a die grinder and a cut off wheel to grind. I will also come behind with the dremal tool and finish it off with it. They do a good job. If You are using a older bit, it is been sharpened already a few times, I also grind the inside of the flutes a little.It makes it easier to grind the point, and get a good edge. Be sure to follow the origional shape of the bit, just grind it so the space between the flukes isnt as thick.

Baldors are nice. I'm seeing the point but not the spurs. Howard's idea with a Dremel, or in my case a Proxxon, to cut them makes sense. I wonder how they do them commercially?
