But Good Anyway.By Jim McCorisonThe product description states "Two-cutter design on even the smallest bits for improved efficiency". The photos show two cutter bits as well. This is not true. What you receive is a set of single cutter bits. I don't know if it is Amazon that bungled it, or DeWalt pulled a fast one and downgraded the product without changing the model information. It doesn't really matter who botched it. What matters is the consumer doesn't get what they thought they were getting.What about the product I did receive? It is very good. Granted they are new and not yet had their first encounter with a nail, but boy do they chew through wood. I used the 2-9/16" bit first for some 2" waste plumbing. It dug through the wood very agressively. The work was remodel on older construction, so the 2x's were well dried. I then followed this with drilling a couple 1-1/4" holes at a 45 degree angle. The center feed spur is long enough that, at least for this size, it would start at that angle and pull the bit down in. Obviously this wouldn't work on the largest bits as the spur isn't long enough.So overall, I rate the product a 5. I added a -3 for false advertising. Thus a final rating of 2. It's a shame really, I probably would have ordered these bits anyway even if the product description and photos had been accurate.12 of 14 people found the following review helpful.Amature Electrician NHGBy A CustomerThese work great. Perfect hole every time. They even impressed my buddy who will only buy milwaukee. The Dewalt set is 10 dollars cheaper and you get 8 bits instead of 7. I would highly recommend this product.6 of 7 people found the following review helpful.OUTSTANDING !!By S. A. ShoreyAs a professional contractor I have been using hole saws for many years. I picked up this set as a back-up, however, it has become the most-used drill set that I reach for. With extra screw heads and the extention it is a truely nice product. Rugged and sharp, I expect many years of good service from these bits.See all 9 customer reviews...
