I love the way it was made in such precision. Thank you Grizzly Industrial Inc. Beside the price is amazing low. I ordered the extra long drill bits. Even more, the case the bits in it is prefect with the index lay out. & Amazon. I couldn't buy anything better than this.
when you need a litte extra, its great.bits are good quality but not excellent quality.well worth the investment
Whenever possible I try to drill a pilot hole using a standard size bit, and then use the 6" bit for the remaining depth. I bought this bit set a few years ago for those rare occasions when I need a bit that's a little longer than normal (pocket holes, etc). I have used them a few dozen times, only in wood (hard and soft), and mostly in a hand held electric drill - I have been pleased with the results.These are not the highest quality drill bits you can buy, but they are good enough for average work. This seems to minimize the flexing problem. Considering you get 13 bits for about the price of one or (maybe) two high quality ones, I think these are a pretty good deal.Regarding flexing, I don't think it's possible to make a thin, long bit that won't flex a little, and many of the bits in this set are thin.
They flex like crazy. So I got what I paid for. For that reason I give it 3 stars. I am impressed with some of the products being produced by Taiwan. If you need long drill bits only once in a while, and have a drill bit sharpener handy, they are not too bad.
These are in the junk category. More importantly, I used one to drill some holes in oak, which is wood, not metal, and they dulled after only a few drillings. I bought these on a whim. I need some long drill bits for a job I was doing, noticed these were the only ones available here at Amazon at the moment, and they were cheap.
Took the bit out and laid it flat on my granite surface plate to check its straightness. So I advise not to buy these drills. all were deflected, none really straight. upon stress the bit simply bent in my hand. I purchased these bits Aug 2004.
Put a bit in my delta drill press and noticed that the business end had a significant wobble. Significant deflection of straightness showed up. Decent bits are relatively ridged, stiff. poor materials, poorly made. Chinese made I believe.
checked several other of the drill bits. You will be disappointed. And.
