Many people say that they "don't make things like they used to." Here at Chapman, our famous mini ratchet and screwdriver bits are essentially unchanged since 1936. We've added more tools and different types of bits since our inception, but the basic assemblies are unchanged.
We precision mill our screwdriver bits on modern equipment that hold tight critical tolerances and produce screwdriver bits with sharp corners, flat ends and no burrs to fit straight and snug into fastener heads. They're heat treated to specific tolerances and then finished with a rust inhibitor black oxide coating.
Our famous mini ratchets are punched from USA stainless steel, hand assembled, inspected and tested before placed into a tool set.
Each set is then also hand inspected, assembled and the accompanying brochure is signed by the assembler. Every kit and part shipped out of our shop is inspected again by a different team member before shipment.

"I bought this set to get all the different bits, I have several other Chapman sets, including my father’s and great uncle’s sets I think that they bought in the 40’s or early 50’s . My dad’s and uncle’s are smaller sets but have the ratchet handles with the beautiful case hardened finish,however I do like the stainless in the new sets. I am very happy with my purchase"

"Best set of screw drivers ever. My wife and I share these tools. She restores Vintage sewing machines and desperately needed the right screwdriver blades for those old machines loaded with machine screws. This our second set of Chapman screw drivers. I bought my first set in the ‘70s and still use them."

"Received the toolkit faster than expected and in great condition. The new kit is an upgrade of a smaller Chapman toolkit I've used for about 40 years and the quality of both kits is outstanding. The new kit will expand it's use to a weekly if not daily basis. Great product and outstanding quality!"

"I purchased my Chapman set at the suggestion by a an acquaintance. It is a very welcomed addition to my toolset. I like the tool case that it comes with. It's made of a seemingly durable plastic. I am impressed by the build quality and the robustness of the materials used to machine the tools. I have not experienced any rounding of my Allen or Torx bits. I hope that this kit is one that I can rely upon for decades to come."

"A very useful tool set that can help you do things ordinary screwdrivers cannot not do. In the short time I have owned the set it has proven it was well worth the cost by enabling me to work in tight quarters without stripping tiny screw heads. Highly recommend this set."
— Forest J. (5/5)
