We used Dormer short length split point HSS when I worked trailer wreck rebuild. That's drilling thousands of holes weekly. When I fabbed a trailer wall that is 3000 holes drilled in aluminum, steel, and stainless. They are quality bits. If you burn them up you are doing it wrong.Learned the hard way on cheap shop tools.
drill bits for example. I need HSS bits so I pay for quality. bought a Drill Hog set....was disappointed and told them so ....so they sent me their "Premium" set and was disappointed with them as well.
My Dad gave me some quality HSS bits that work great. Don't know the brand.
If anyone here has a recommendation for great drill bits , let me know.......and not ones that work great for 3-4 times and then get dull ( I do use cutting oil ). I don't need a set. I only need 3-4 specific sizes .
I have had good luck with quality Dewalt bits.
