Description

Tct carbide reversible knives-Carbide inserts 2 - ARUNDA

TCT Carbide Reversible Knives (Carbide Inserts with 2 cutting edges) for the Arunda System are high-precision, indexable replacement blades designed specifically for the heavy-duty router bits used in timber framing. The Arunda system relies on these premium tungsten carbide inserts to mill massive, structural wood dovetail joints cleanly and efficiently.

Technical Specifications & Features

Cutting Edges: 2-sided indexable design. When one side becomes dull, you loosen the clamping screw, flip the knife 180 degrees, and tighten it down to instantly deploy a fresh, razor-sharp edge.
Material Composite: Premium micro-grain Solid Tungsten Carbide (TCT). Carbide maintains its sharp cutting profile up to 10 times longer than traditional High-Speed Steel (HSS), making it ideal for the dense resin and tough grains of heavy timber.
System Compatibility: Designed specifically for the high-torque Mafell LO 65Ec Hand Router when paired with Arunda Dovetail System B-Class and N-Class milling templates.

Why the 2-Sided Design Matters for Arunda

Unlike 4-sided square inserts used in surface planers, the Arunda inserts are elongated rectangular blades. The 2-sided design ensures:

Maximized Structural Rigidity: Prevents the blade from shifting or vibrating under intense lateral forces during deep dovetail profiling.
Flawless Joint Alignment: High manufacturing tolerance (often down to 0.02mm) ensures both sides sit flush in the router head, preventing unsightly step-marks or loose-fitting joints.
Reduced Tear-out: Optimized cutting angles slice cleanly across both softwoods (like Pine and Spruce) and dense hardwoods (like Oak).
