Title: Mixed feelings at best
Product review: I have been using these bits on red oak for a project today. They work fine if I am drilling through 3/4 in boards but when drilling into end grain the fluting does not clear out quickly enough and then they discolor and come out with burnt material and smoke rolling off. This happens less on low speed for my drill, on high speed it is near flames. Happens on my cordless drill so I tried my drill press and had the same result. Again, pre-drilling the boards and countersinking them the bit is great as for going full depth in hardwood - not so much; I went back to a regular bits. Also note, when using the drill press - raising the bit out of the hole 3 times during drilling minimize the burning as it cleared out the bit - that is not the intent of this for me since it was meant to be used on a cordless drill.
Would you say this review depicts the product in a flattering or unflattering light?
