Good Drill Bits... Why?
Why is it so hard to find good drill bits?
What's your favorite, long lasting drill bit?
All these titanium bits that are supposed to cut steel well don't impress me very much.

I agree quality makes a big difference. I've never found decent ones locally, but often order Ruko brand online and have been extremely pleased.

With drill bits one usually gets what they pay for. I get el-cheapos for drilling through plastic and sheetmetal but if it is drilling though frame rails I'll splurge on the best ones I can find.

Guys, that's what I am saying... I can't find GOOD ones. I didn't say anything about cost or buying them "low cost" or cheap.
I'll pay for a good set of drill bits that actually last longer than one (or half of one) project.
Got a link to where you buy the RUKO? I've not heard of them.

Learn to sharpen them. Its not that hard. 30 secs, Its all in the twist of the arm. You want the back of the point to be lower than front as you twist it. Look at a new one and see how the bevel on the point looks.
Enco Supply you can buy different grade and in bulk and size of your choice

Shop someplace besides Lowes or Home Depot. All they carry is junk.
Dh used to buy them at Grainger.

I haven't found a good set of drill bits in local stores for a very long time.
I would imagine I could at a good industrial supply house that supplies tools for folks at the plants and refineries, but I don't get to those places much.
This place might have some good ones, I'll likely try a set from there next time I need one.

Those twist drills that they say are titanium, are many times plated. Titanium itself doesn't have the flexability to make tools from. When the outer layer is sharpened or wears off, all you have is a cheap high carbon, twist drill.
I have a set of cobalt twist drills, made by Starrett, that work really well.
I agree with Txrider's statement about being able to find a good set at industrial supply stores. Ask at the local machine shop for a good source.

Going to add, proper drill speed for the material.
I get mine through work and we order from Production Tool Supply.
And keep them sharp

A million years ago I worked for a company that made drill bits. Spent a lot of time testing bits and bit coatings. As I recall, at no time did a coated bit cut any better than an uncoated bit, and usually it was slower. Coatings dull a cutting edge.
Bosch bits are available at Home Depot and the like, and do work well.
Care and maintenance are another part of the equation. People, including me, spin their bits too fast, push too hard, don't lubricate, and push harder as the bit starts to dull, overheating it and burning the edge right off. Slow down, lighten up, lubricate, and sharpen. Your bits will last longer and cut far better. That includes cheap ones.
My drill doctor is my friend. Oh, I can sharpen bits by hand, I've done it for years. But the drill doctor does a fine job and requires no special operator skills.
