As stated earlier, drilling is an acquired skill. Basically you need to have a general knowledge of what you are drilling. If thick material, slow speeds & cutting fluid or oil. Thin materials usually don't require cutting fluid, or oil. The faster you run it & the more pressure you use determines the life expectancy of the bit. I had a rookie helper working for me drilling metal top plates with a hole saw in an office area. He ran the drill "full tilt boogie" he burned up the pilot bit & the hole saw. All he accomplished was costing me money for new bits & hole saws, & work hardening the metal he was trying to drill through.
I used to run automatic screw machines and it was amazing how long a drill would stay sharp with the right spindle speed and feed rate. Even drilling 6" stainless idler gear blanks. The shavings were treacherous though. LOL

Little chart I found on the net Drill Speed Guide
As much as liked the old electric hand drills, having variable speed control in the trigger is just great!!
OTH Reverse switch can be a curse. When we were teaching young adults in woodwork skills, it was hard to get them not to reverse.

My Mac dealer guarantee 1/8 bits. I feel guilty. Snap-on double 1/8 inch bits are badass but no warranty. Everyone should have step drills. I stay away from all of the titanium cobalt stuff. Good old high speed with a break guarantee over 1/4 inch seems fair to me. Learn to sharpen.

I use Klutch from Northern tool, if you lube them up before you use them they will last a long time.
And neither look good to me
Cobalt
not "Kobalt"
I've found that cobalt bits are way less likely to over heat and blue the end.
My local Lowes lists an index set for $32
The singles I've been buying nearly all have a pilot point.
That's cool, too.
They are 35-40% more than the "titanium" bits but are well worth it as one cobalt bit used correctly will last longer then 5 or more lesser bits.
Slow, and big chip.
You can tell it's working.

When possible, I use my HF drill press. Just cuts better than by hand.

Lol, The HF's walk off project as soon as the motor turns the bit. The Ryobi starts making chips.
