Chapman Interchangeability

Chapman makes the most versatile USA miniature ratchet and insert bit sets on the market. People use our tools where a regular screwdriver or hex key will not fit or provide adequate torque. Each of our bits are designed to work independently, or in conjunction with our other interchangeable ratchets, screwdriver handles or extensions.

• Screwdriver bits have knurled ends to use for finger tightening. Learn more about our screwdriver bits
• Famous midget ratchet is under 4" long and provides over 200 inch/lbs or torque (equal to 4x the torque of a large screwdriver). Learn more about our ratchet
