Отзыв о Набор сверл EZARC с зенковкой по дереву (шестигранный хвостовик 1/4 дюйма) - 4, 6, 8 и 10 конических сверл с сверлильным резаком для деревообработки от William Mahajan

I tried these in my drill press and discovered some wobbles on the two longest drills. This is not a big deal as the drill part of the cutter is only the guide for the actual hole cutter. They were not as sharp as some I’ve had for years in my shop. The plug cutter took a lot of pressure just to get it to penetrate the wood 3/8 of an inch. I tried these on oak as well as pine and was pretty disappointed. I would not recommend using these in a drill motor. A drill press is your best option because of the extra pressure a press delivers.
