Stainless steel is difficult to machine due to its strength, heat resistance, and tendency to harden during cutting. Dohre end mills are specifically engineered for stainless steel, combining high-hardness carbide substrates, precise geometries, and advanced coatings to achieve superior durability, excellent surface finishes, and long tool life.
Machining stainless steel involves high cutting forces and poor heat dissipation. The material tends to work harden quickly, increasing tool wear and the risk of built-up edges. Dohre’s end mills address these issues with optimized flute designs, sharp cutting edges, and temperature-resistant coatings.
High cutting resistance: Requires reinforced core and edge toughness.
Poor thermal conductivity: Demands coatings with superior heat resistance.
Chip adhesion: Special flute polishing minimizes built-up edge.
Work-hardening: Needs aggressive geometry to maintain chip flow.
Ideal for slotting, side milling, and face milling with stable performance and long life.
Perfect for 3D contouring and die finishing, delivering excellent surface accuracy.
Reduce edge chipping and extend life during semi-finishing operations.
Chip-splitter design reduces cutting load and improves stability for roughing stainless steel blocks.
Variable pitch and helix control vibration during high-speed cutting.
TiAlN, AlTiN, or DLC coatings ensure heat resistance and anti-adhesion performance.
100% virgin micro-grain tungsten carbide for superior hardness.
Advanced CNC grinding for edge precision and concentricity.
Polished flutes improve chip evacuation and reduce friction.
Coating technology ensures longer life under high temperature.
Custom geometry and coatings available for specific grades (304, 316, 17-4PH).
| Material | Vc (m/min) | fz (mm/tooth) | ap (mm) | Coolant |
|---|---|---|---|---|
| 304 | 80–120 | 0.03–0.08 | 0.5–2.0 | Flood/MQL |
| 316L | 70–110 | 0.02–0.06 | 0.5–1.5 | Flood cooling |
