Amana’s E-Z Change replaceable head router bits let you swap out a cutting head without changing an entire router bit or sharpening the cutting edges. The disposable carbide-tipped cutters are mounted on alloy steel arbors and come in plunging/template, flushtrim, dado cleanout, bevel and no-file profiles. Each contains a shank body, carbide-tipped cutter and a bearing. (Replacement parts are also available for each profile.) The E-Change profiles offer woodworkers a less expensive option for router bits, with prices in 2010 starting at $18.75 for the template profile.
