My rotary hammer stopped working after about the 6th or 7th use. It doesn't make much sense to me to use a hammer drill, but when I do use it it's nice to have one. I contacted DeWalt customer service who was very friendly and helpful. They emailed me a return label. I printed it out and mailed it from my office. I see a lot of deliveries every day. A few days later I got a call from the warranty center. The young lady on the phone told me that she received the package. She then told me it would cost her $75 to fix the hammer drill. I said this drill comes with a 3 year limited warranty. I've only used this drill 6 or 7 times since buying it. I asked her how it couldn't be a factory defect? I kept asking her what was wrong with the drill? She informed me that she had no such information. I told her to send the drill back to me. After receiving the drill back, I checked the decals on the drill. All were in place, the drill wasn't even taken apart for inspection. How could the warranty center tell me it wasn't a factory defect when they didn't even check the drill? In the picture above there is a protective sticker under the battery. The notch in the corner is the one I made to see if they opened the drill. I will no longer buy this brand or any other brands they have. I pay a name premium because I thought they stood behind their products. I have bought many products from this brand. For my personal use. I bought 200 to 300 times more for the company I work for. I will no longer buy for myself or for my company if warranty service is provided in this manner.
