I'm heading to HF today. What are the best type of drill bits to get to drilling out rivets and such. I see they have titanium and carbide plus a few others. I'm using a drill press. Also if anyone has a 20% off coupon could you attach it to your post.

Ive had luck with both of those kinds of bits. The real trick, is to run the drill press on a slow speed, and use lot of oil when drilling. Go slow and stop the drill to clear the metal shavings often. When drilling the long trunion rivets, only do maybe 1/8 of an inch before you stop to clear the bit & the hole. This also gives your bit a chance to cool down a bit, and of course add a little more oil to the bit. Good luck. After you get the hang of it, it actually goes fairly quickly. Also, start with a small bit and after you drill the entire length, then step up to a slightly larger bit and enlarge the hole. You may have to step up 2 or 3 times.

I have a set of the HF cheap drills that work just fine for me. Like the man said, just drill slow and use oil, making sure to clear the hole frequently.

They have bits of the same size in packs of 8 or 10, for like 4 dollars thatis what I use.

I got a complete cheap set of titanium set that I use. They work great. I also have a carbide bit I use for drilling out those long yugo rivets. Yeah, you will probably pay $2-$3 for a carbide bit, but it will last for more kits than you can ever have the time to put togeather.

I ran a machine shop for years and I would suggest that you buy quality and buy once. A good set of carbide bits should cost you around $75.00 They should last a lifetime.

Never bought good quality ones before, a good bit last a lifetime? Do you have to resharpen or they just last?

Don't forget to get a Drill Doctor. Your bits will last forever. I have sharpened dull bits that cut better than new with a $10 garage sale Drill Doctor.
