The Sutton R110 is a replacement blade set for the Sutton R109 adjustable hand reamer. Each set is matched to one reamer size, so when the cutting blades wear you can restore the reamer rather than replace the whole tool.There are 15 sizes in this listing, from MA (12.00 to 13.50 mm) to MO (69.75 to 85.00 mm), using the same size codes and ranges as the R109 reamer. Blades are listed for the larger reamer sizes only: MA to MO. The smaller R109 sizes (MA8 to MA2) have no separate blade set listed.Which size do I need?Match the size code of your R109 reamer, or the hole range it covers.
