Kreg tools fill a unique niche in woodworking tools, making specialty tools that create solutions to tough jobs. I'm a fan of theirs because they think outside the box and look for solutions it seems. This is just one of their basic tools, consisting of two 3" hardened steel bits for tight holes and 6" bits for easy use. I bought them as a backup as they come with some kits. I have many tools and screws for systems. These tools always exceed my expectations. I hate to say it but I have no particular complaints about these instruments as they are well made. I also recommend them all, so feel free to try them out. I'm giving them 4 stars because they're nothing special, but I think this is a good score for boring old beats.
