Key Specifications & Features:

Strengths
- Spiral geometry produces a shearing cut rather than a chopping cut -- significantly smoother surface
- Solid carbide (not just carbide tips) for maximum hardness and edge retention
- Shear cut dramatically reduces tearout in difficult grain directions
- The professional choice for fine furniture template routing where surface quality is critical
Limitations
- Solid carbide is more brittle -- requires careful handling

- Freud's TiCo carbide and consistent manufacturing ensure clean bearing-guided cuts
- The correct bit for routing full-thickness furniture parts against a template
Limitations
- Higher price than smaller-diameter flush trim bits
- Tall cutting height makes it inappropriate for shallow cuts -- too much cutter exposed
