Are SpeTool spiral router bits made of solid carbide?

🔍 Yes – SpeTool spiral bits are made from **industrial-grade solid carbide** for durability and precision. Solid carbide construction means the entire cutting portion is carbide (not just a coating), which allows for sharper cutting edges and complex flute geometries. This is one reason these bits stay sharp longer and cut cleaner. For example, the SpeTool down-cut spiral bits use a solid carbide body with a special SPE-X coating for extended life:contentReference[oaicite:7]{index=7}. Solid carbide bits can handle tough materials and high router speeds without rapidly dulling, so you can expect long life and consistent performance from SpeTool’s spiral bits.
