Amana Tool Spektra™ Solid Carbide 2-Flute Up-Cut Spiral Plunge Router Bit, 3/16" Diameter x 1" Cutting Height x 1/4" Shank
2-Flute Up-Cut
3/16-Inch Diameter
Amana Tool 48330-K is a two-flute solid-carbide up-cut spiral plunge router bit with a 3/16-inch diameter, 1-inch cutting height, 1/4-inch shank, and 3-inch overall length. The up-cut spiral pulls chips upward for efficient evacuation, deeper penetration with less stress on the tool, and clean mortising, groove, and dado work in wood and panel materials.
Main Product Description
Amana Tool 48330-K is the exact two-flute solid-carbide Spektra™ up-cut spiral plunge router bit shown on its dedicated official product page. It combines a 3/16-inch cutting diameter, 1-inch cutting height, 1/4-inch shank, and 3-inch overall length in a long-cut 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 up-cut direction shears from the bottom upward and pulls chips out of the cut, supporting deeper penetration with less stress on the tool. It is identified as an excellent choice for mortising and for grooves and dado cuts in particleboard, plywood, and laminate.
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 product page links the Spektra™ spiral-plunge family chart, which publishes an 18,000 RPM CNC operating reference.
Best Fit Applications
Product Highlights
Up-Cut Chip Evacuation
The verified up-cut direction pulls chips upward from the cut, supporting deeper penetration with less stress on the tool and making it an excellent mortising choice.
Clean Spiral-Plunge Geometry
Spiral-flute shearing action supports an accurate finish while the augering action clears chips during groove, dado, and production-routing applications.
Spektra™ nACo® Coating
The micro-thin nanocomposite ceramic coating helps retain cutting-edge sharpness and lubricity while resisting heat and oxidation in abrasive routing materials.
Compatibility & Installation Notes
Confirm exact SKU 48330-K, a compatible 1/4-inch collet, secure workholding, and sufficient clearance for the 1-inch cutting height and 3-inch overall length. The linked 18,000 RPM family chart is a recommendation and must be matched to the material, machine, tooling condition, and setup. Follow all Amana Tool and machine-manufacturer safety documentation.
