I'm considering buying one of those 115 piece drill bit sets with fractional, number, and letter sizes. I'm looking for bits that will hold up well even when drilling steel. I've got a "Drill Doctor" sharpener on order. Basically, I'm tired of not having the right size on hand and having to run to the hardware store when a bit goes dull. Using the sharpener, it seems like I want bits which have strong/hardened steel through and through rather than a surface coating.
I see that Harbor Freight sells two kinds:
Titanium nitride coated M2 (whatever that means) steel : $39.99
Cobalt : 79.99 (on sale regularly $99.99)
They're both made by Drill Master.
I'm not against spending more money for quality tools so I'm leaning towards the cobalt. However I'm not sure about Harbor Freight's offering. Does anyone out there have an idea about the quality of these bits? Perhaps there's a better place to get drill bits?
Thanks for any guidance.
