Mentioning this because obviously these have never been worth $45. I'm not saying that wasn't once a price, just that they are mediocre bits.
You can see in the reviews that you'll only make it a millimeter or two into aluminum before needing to replace the bit.
That is, if you don't use cutting oil like those dumb reviewers. But if you do use a lot of cutting oil they'll easily go through aluminum.
Yeah this seems like about the average price, nothing amazing

Not really. The sizes stop at 1/4" and the value is in the larger up to 1/2"
For consumer DeWalt bits, I would and have used this split point 14pc DWA1184 set[amazon.com] for $15.
This Bosch CO14B[amazon.com] 14pc set for $27 is now a low for Amazon, but has been less ($20 last month) by a third party. Being M42 cobalt, they are superior to the DeWalt before getting into better and more costly brands like Morse, Hanson, Triumph, etc. This set is also in the discount deal for Bosch tools.
There is nothing the matter with the OP, except for that I cannot resharpen that pilot point so easily as say, a split point or regular 135 degree. The 'titanium' is mostly a sales gimmick, as it is a plating that quickly wears off, but does help a little with metal shaving removal... a little. Proper speed and lubrication are imperative for the longevity of any bit.

It depends on the type, thickness, hole size and speed. Drilling .250 or thicker type 6061 or 6063 with up to 1/2" hole at up to 2500 rpm, we use a wax lubricant that helps bits last longer between sharpening. For .125 and thinner at same or less speed, no lubricant. I hate cleaning the lubricant off that will catch metal chips that will scratch the powder coated or anodized finish if not very careful.
If using soft drill bits on mill finish aluminum, I suppose oil would help, but by the time I clean up the mess oil causes for where it shows, I could resharpen multiple bits. We have used this brand of wax[amazon.com] for drill bits, metal cutting saw blades and hole saws, drill taps, metal and wood screws, etc., for several decades. The 6"x6"x6" size is wrong, as these are about 2" x 11" .... I cut the tube in half for saws and in thirds for everything else. There are other brands, but know this one that minimizes the mess over using oil on most anything we do; including steel that is to be welded and/or painted.

Who uses cutting oil on aluminum?
