I reviewed the 3" long version of this endmill of the same type from the same seller, and I'm quite happy with it. This one is titled "extra long reach" which is technically true, and it is 4" long as described, however the picture with this item is of a different end mill, a 4x3/8", so it looks significantly longer if you are assuming it is the 1/2" endmill in the title. I was expecting more like a 4.5-5x1/2" cutter based on the photo, so that's my own fault for not reading carefully. No complaints with the product, as it's doing a fine job. The photo, however, should be swapped with the appropriate 4x1/2" tool that is actually described to avoid customer confusion.

Good value, 2 bits for less than one compared to other retailers.
