The professional R25 concave quarter-round router bit is designed for precise wood processing, ideal for creating flutes, decorative grooves, and deep rounds. The brazed HSS M2 (6.5% tungsten) inserts ensure a clean cut, high wear resistance, and durability in intensive use.

⚠️ The cutter is available in two working directions:

Right (above the wood) and Left (below the wood) – allowing you to choose the optimal option for your feed direction and machine configuration.

Features and Benefits:

25 mm Concave Radius – ideal for deep profiles, flutes, and decorative shapes

Premium HSS M2 – durable inserts, consistent performance, and long lifespan

Clean and Precise Cut – optimized geometry for a smooth finish without fiber tearing

High Versatility – suitable for furniture, architectural elements, and artisanal woodworking

Working Stability – balanced body, ideal for professional machines with standard bore

📌 Choose the appropriate working direction (right or left) and achieve perfect contours for solid wood projects.

⚠️ Usage Limitations:

❌ We do not recommend the HSS version for chipboard, MDF, HDF, or very hard exotic wood.

❌ For composite materials or demanding applications, choose the version with Carbide inserts

HSS COMPATIBILITY:

The router bit can be mounted on most standard milling machines, suitable for both manual work and CNC machines with moderate feed rates.

Compatibility Explanations (%):

90–80%: Optimal performance, the cutter works efficiently and durably.

79–60%: Good processing, but requires maintenance (sharpening or cooling).

<60%: Wood is too hard or oily, leading to rapid wear of the HSS M2 cutter.

Recommendation: For exotic or very hard woods, carbide (Widia) cutters would be a more suitable choice.
