$3 coupon for this review. and I have a feeling that as long as you have other cutting tools like HSS or drill bits to cut large chunks of material you will enjoy the nice finish it gives (with the right feed and speed of course). I would like this to be part of a set with other carbide cutting tools. Otherwise I'm happy. I haven't had to call customer service yet as Prime came two days later. I will not buy again because the reason I bought this one is so I can easily replace these inserts. Getting the earbuds is my only concern as I don't know who makes them but they are reasonably priced at the moment. I hope it will match carbide inserts from other manufacturers. Bottom line: if this drill is still working in a year, I'll be happy with my purchase.
