I've had a heck of a time with drill bits today. Needed 1/8, 3/16, and 1/4. I had some HF crappy of the two small sizes, couldn't even get them to go through 1/8 1080 at the slowest speed on my craftsman drill press (usually can get a couple of holes out of each bit). Went to Lowes and got those three sizes in the "Black Gold" bits, and a 1/8 in the DeWalt. The dewalt worked well, drilled about 20 holes so far with no problems. The 3/16 smoked on the first hole, chasing a 1/8 inch drilled pilot. Same with the 1/4. I was able to finally get another 3/16 to work, but still have some 1/4 holes to drill. Any ideas why I should have so much trouble in the bigger sizes? Any readily available bits that would work better? GRRR on drill bits!
