302 Z28 Another vote for the step drill, and also for The Drill Doctor. I don't buy drill bits any longer since I got a Drill Doctor for Christmas, unless I break one.

Old Fool Like others have stated, for common size holes drilled in light gauge metal you cannot beat a good step drill IMHO.

brucer69 i'm a tool &die maker by trade for the past 20 years.

i would recommend either cleveland or precision twist drills in cobalt. you'll pay more for the cobalt drills but they are far better than the regular high speed steel drills..

and a drill doctor can be your friend if you cant hand sharpen drills.

deidrea8 you can try ****** They seem to always have everything I need for home improvement.

trees My son just sent me a Drill Dr and it is a great tool. This one has a diamond wheel so it will handle HS, Carbide, Cobalt and Titainium. Unfortunately, I do not have the eyes to do the job the tool is capable of, but it sure beats what I can do on a grinder. Guess I will have to invest in a lighted magnifier now.

1ownerT Some of the best I have found are the Crown Point bits from Lawson Products, pricey though.

bentwings Ha ha Vince I was going to suggest a Drill Doctor too. I did my time in the machine shop and learned to sharpen drills early on. It is nice to have a dead perfect drill when you need it however.

The Unibits work great for most butchering jobs and the "long" drills will finish off the hole in thicker metal. (correct spelling)

schnitz Great post, Chuck.

4 Jaw Chuck I have a complete set of Cleveland drills in letter, fractional and number in a nice box. Cost me $180 for the whole set back 15 years ago.

I also have numerous sets of cheap drills that get used around the house when I don't want to risk breaking my Clevland drills such as drywall and woodwork etc. I don't think I have a single drill that hasn't been resharpened a hundred times, all done on a bench grinder by hand.

Without exception the cheap drills lose their hardness the farther you grind back, the Cleveland drills are hard all the way to the hilt. There is a time and place for all these drill bits in my box but when it comes time to drill a hole within 0.001" size in a material like 416 SS or 245 tool steel I don't bother with the cheap drills.

I guess what I am trying to say is most people don't need a drill bit like the Cleveland all the time, but when it comes time to modify one for use as an "old school" reamer I wouldn't even attempt such a thing with a cheap drill. The machine shops I worked in all used Cleveland drills, some even switched over when they seen how well they hold an edge when they seen the work mine could produce all day long.

The biggest problem is most people have no clue on how to use a drill bit properly or how to resharpen them and the risk of breakage is high, not a place for a $7 drill. One thing is for sure I have never seen an off center ground drill from Cleveland, they have exceptional quality control.

I have a cheap chinese set of fractional drills that look just horrible, the flutes look almost rough cast. However they are really tough and take abuse like no other drill I have ever used and just don't break. They get used for things like maganese castings that are full of scale and sand inclusions because they are so durable. For the same job the Cleveland drill would chip and possibly break.

There is a time and place for everything, just like life.

Almost makes me wonder which is worse. Those bits, or the 10 screwdrivers for $3.99 weekly special.......

True, but you do have to admit that a HF set (buddy of mine from maintenance bought them) is absolute JUNK. His set was the "high end" from them, and honestly, you could drill a hole in your foot trying to drill a hole in a wall. We could tilt a slab in the shop to a 45 degree angle, and the bit would slide, not roll, off it. I have a few Irwin bits, a set of DeWalt, and a set of Craftsman Split Point bits. So far, so good. Except the occasional 1/8" I break.....

4 Jaw Chuck Cleveland drills are the best drills I have ever used...period. They are expensive for a reason.

302 Z28 I bought a Drill Doctor and quit buying drill bits.
