E-Z Change Replaceable Head Bits
E-Z Change replaceable head router bits from Amana are an economical alternative to standard router bits. They feature replaceable head carbide tipped cutters, saving you money by replaceing only the cutters when the knives become dull, instead of the entire tool. You won't need a second bit while yours is being sharpened - just swap the cutter head and it will always match up with the bearing. You won't lose your setup because the EZ-Change cutters can be replaced without removing the arbor from the router collet. Interlocking hex design guarantees that the cutting surfaces will not slip during use.
Replaces OCEMCO system also know as Paso Robles Carbide.
