Most helpful customer reviews0 of 0 people found the following review helpful.not the quality i expectedBy Nicholas SmithLet me preface this review by saying that I am a self-employed contractor who owns a TON of DeWalt tools and swear by the brand, and that I also own other forstner style bits by both Freud and Irwin.This item had three major flaws:a) The cutting edge (which is usually sharp as a razor) looked like someone had dropped it or banged it on something twice and had two large (3/8" wide) dings, one rounded and one with a squared edge. Due to the inexpensive price, this leads me to believe it may have been a factory second?b) The replaceable bit in the center which guides and feeds the cutter came loose about every third hole it drilled.c) Due to the flaws in the cutting edge (in my opinion) it put so much extra torque and drag on the drill that it burned up the motor on a heavy duty gear-reduced 1/2" DeWalt drill which stated that it was made to run this style of bit, and then sheared a 3/4" drive spindle on a 2 ton drill press (in a factory used to fabricate scaffolding) when allowed to self-feed. It also started splitting my lumber down the middle when the hole was only halfway through (always on the dinged up cutting edge, even after being roughly straightened with a file).Needless to say, this one is on the shelf with NO plans to use it again unless absolutely necessary.I LOVE my DeWalt tools, but DON'T buy this one unless you have a crazy oversized heavy duty machine to run it with!See all 1 customer reviews...
