Many people say that they "don't make things like they used to." Here at Chapman, our famous midget 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 midget 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.
