Solid Carbide High-Performance Tools: Roughing & Finishing End Mills

Maximum Material Removal Rate Meets Highest Precision

For economical manufacturing, dividing processes into roughing and finishing is essential. We offer perfectly coordinated solid carbide solutions that increase your productivity and optimize workpiece quality.


1. Solid Carbide Roughing End Mills (HPC Roughing)

The powerhouses for rough work. These end mills are designed for maximum material removal rates.

  • Cord tooth pattern: Breaks chips into small segments, reduces cutting forces, and protects the machine.

  • Core stability: Reinforced core diameter for maximum stability at high feed rates.

  • Coating: Special heat-resistant coatings for dry high-performance machining.

2. Solid Carbide Finishing End Mills (High-Finish)

For surfaces like polished. When precision and aesthetics are paramount.

  • Multi-flute design: High number of teeth (Z=4 to Z=8) for extremely smooth surfaces and high peripheral speeds.

  • Unequal spacing: Prevents vibrations and oscillations to eliminate micro-cracks and chatter marks.

  • Tightest tolerances: Highest concentricity for dimensionally accurate fits.


Current Market Situation & Pricing (As of: February 2026)

The market for strategic raw materials, especially tungsten carbide, is currently experiencing extreme fluctuations. Compared to the previous year, we are seeing significant price dynamics driven by a shortage of global supplies and unstable supply chains.

As raw material costs constitute a significant portion of the manufacturing costs of solid carbide tools, this directly impacts our pricing.

Important note on pricing:

Due to the currently uncertain price development in the raw material market, we cannot list long-term fixed prices in our catalogs.

  • Prices are calculated daily and upon request only.

  • Price concessions only become valid with our written order confirmation.

  • However, we guarantee to always determine the best possible price-performance ratio for you through optimized inventory management and direct purchasing.
