Amana Tool 46244-K is the exact two-flute solid-carbide Spektra™ down-cut spiral plunge router bit shown on its dedicated official product page. It combines a 3/32-inch cutting diameter, 1/4-inch cutting height, 1/4-inch shank, and 2-inch overall length in a compact precision-routing format.

Spiral flutes combine a shearing action at the cutting edge with an augering action for chip clearance. Amana Tool states that the down-cut direction cuts from the surface downward, leaving a smooth edge at the workpiece surface. The tool is suited to grooves and dado cuts in particleboard, plywood, laminate, melamine, MDF, cork, veneered plywood, and wood.

The solid-carbide body uses a specialized carbide grade with increased-clearance geometry, polished flutes, and sharp cutting edges. Spektra™ nACo® nanocomposite ceramic coating is designed to help retain edge sharpness and lubricity while resisting heat and oxidation. The official chart identifies 46244-K as a two-flute 3/32-inch down-cut tool and publishes an 18,000 RPM CNC operating reference.
