This is an expansion, or adjustable, hand reamer. These reamers are designed to be expandable to a size for situations where the exact diameter reamer may not be available. This reamer can be used for a stock appearing carburetor with a larger bore.

Reamer has a range of 19.75mm (.781) to a maximum of 21.50mm (.850)

Couple tips for these reamers:
Only remove small amounts of material with each pass. Most builders will secure the reamer in a bench vise and turn the body of the carburetor onto the reamer.

If working with larger amounts of material or performing the same size reaming operation a number of different times, use a second reamer as the adjustable blade reamer working up to the final finish, and keep one reamer set as your final/finish reamer set-up for maximum bore size.
