Our famous stainless steel mini ratchet provides about 200 in lbs of torque with a 20 tooth gear and an 18 degree working arc.
- Customers tell us that this "is the ratchet used to feed lube through a Lyman lube and sizer"
- Two tone ratchets have a silver front (drive in) and a colored back (drive out) so it's easy to tell whether you're driving in or out
- The painted halves are electroplated with the same wear resistant paint used on handcuffs
New! 4 Pack is great for lean manufacturing or 4 commonly used insert bits
- Bright coatings are useful as they stand out if they're left in a machine/cluttered work bench (Materials and workmanship warranty applies, but does not cover scratches or gouges in the coating).
New! Flame treated ratchets!
- This is how our ratchets were made in 1930's and 1940's. The Flame treating is purely cosmetic and makes each ratchet unique.
New! Green & Silver Powder Coated ratchets!
- Unlike our other two tone ratchets, this ratchet is colorized by using a durable powder coating.
- This ratchet has a Green front (drive in) and a silver (drive out) so it's easy to tell whether you're driving in or out
Please note: Chapman ratchets are designed to be used with Chapman bits. While they may fit other 1/4" Hex drive bits or extensions, they are not guaranteed to work as a universal tool. Replacement colored ratchets of the same color cannot be guaranteed.
CM-13 mini ratchet is rated at 200" lbs of torque, which is the typical torque of 4 large screwdrivers. Most of our bits are rated at less than 200" lbs based on the torque of the screws they fit.

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.
