I'm pretty sure you should have to clean up each bit yourself, because I feel like I should have paid the asking price just to ship this much.
I can now give my neighbor a 15/16" drill bit if I borrow one, knowing that I won't feel bad if I break, bend, or lose one.
I noticed that some reviews said the drill bits were not sharp, but that was not true.
I almost spent three or four times more for "name brand" bits, but I am really glad that I didn't, because they seem to work like new and will not need replacing or sharpening any time soon.
I bought this drill set from this company and I have to say I am very happy with it. The drill bits are beautiful, the case is quality, and it even came with a free bottle opener just to say thank you, try getting that from a set priced three times higher than this
Question & Answers
Q:
Will they be able to drill hard stainless steel?
A:
The bit set I received did not drill aluminum until I used a fine diamond file to hone the cutting edge, which had small burrs.
Q:
Is it possible for it to drill through Brick?
A:
They are mostly used for drilling metal but they are not designed for drilling masonry which includes concrete, concrete blocks, and brick.
Q:
Why don't they say hss-co or m35/m42 if they are actually cobalt?
A:
I bought the worst bits from Amazon and half of them were bent. The ones that were straight were very sharp the first use.
Q:
Is this me or the bit, when running at 760rpm drilling aluminum with a pilot hole, is it walking?
A:
I ran the 5/8" bit down a 1/4" pilot for 16 holes in mild steel and it worked well for me. If you resharpen them as I did, you will lose the split point.
Q:
Will these bits fit a jaw chuck?
A:
Measure your brace chuck inner diameter and note the 1/2" shank dia. on the drills.
