Concave Half-Round Router Bit R4 – R60 mm | Convex Wood Profile – HSS M2 / HW (K40)

🔧 MAIN FEATURES:

• Efficient Machining: the concave profile of the cutter produces a uniform and aesthetic convex result on wood, across the entire R4–R60 mm radius range.
• Durable Blades: 4 brazed teeth made of HSS M2 or HW (K40), resistant to intensive use.
• HW (K40) for Composites: metallic carbide inserts resist the abrasive wear of synthetic binders in MDF, chipboard, and HDF, where HSS would wear prematurely.
• High Precision: ideal for fine details and decorative work.
• Versatility: suitable for furniture, frames, panels, or hobby projects.
• Long-Term Investment: inserts can be successively resharpened at a specialized center (to maintain the attack angle), and in case of advanced wear, the cutter body can be re-brazed with new inserts.
• Black Oxide Finish: the cutter steel is treated with black oxidation (bluing), a treatment that gives it its characteristic black color and additional protection against corrosion.
• Compatible with Classic Table Routers and 4-Sided Machines: mounts on both classic table routers with spindles and 4-sided machines, for flexible integration into the workshop's production flow.
• Custom Radius on Request: if your project requires a specific radius outside the standard range, you can contact us with the technical drawing of your project.
