Split Sleeve for 1/4″ Router Bit Adapters

The AC303 is a split sleeve for fitting 1/4-inch shank router bits in the Schmidt router bit adapter system. Router bit adapters (AC300-302) allow standard router bits to be mounted in a mortising machine or similar equipment; the split sleeve reduces the adapter bore to accept a 1/4-inch router bit shank, clamping the shank securely in the adapter. Source data for AC303 is minimal — the title shows only partial information. Contact Schmidt to confirm which adapter(s) the AC303 split sleeve is compatible with (AC300, AC301, AC302, or all three) and the full sleeve dimensions. For the Powermatic adapter, see AC300.
