QRC TM -2000 Reamer Blade
To remove the reamer blade, place the 9/16” (14mm)
spanner wrench, part no. QRC-440, on the hex flats
at the end of the extension shaft and the QRC-441
wrench on the top of the reamer blade.
The cutter is removed by turning counterclockwise
when viewed from above. Considerable force may be
required to loosen the reamer blade since it tightens
naturally as the reamer operates.
Please refer to Table 1 for reamer blade options.
