Simultaneously matched with DEWALT taps to make tapping pre-drilled trailer holes easier and faster. This bit went through about a hundred holes before finally breaking. The only reason it broke was because it didn't hold the drill straight when backing out of the hole. DEWALT didn't even make two threaded holes. The beveled end of the drill is great, but it means you always have to pull the drill out of the hole. collect them all. Worth the money knowing they break often.
