Product Details
Industrial HSS-Co Roughing End Mill (TiN Coated)
Maximum Toughness and Cost-Efficiency for Heavy Material Removal
Maximize your heavy-duty roughing operations without shattering your tooling budget. Xiaoman Tools' HSS-Co Roughing End Mills are engineered for workshops that require extreme toughness and resistance to chipping, especially on older or less rigid milling machines. Forged from premium Cobalt-alloyed High-Speed Steel (HSS-Co) and protected by a durable TiN (Titanium Nitride) coating, these cutters withstand significantly higher cutting temperatures than standard HSS. Featuring a specialized corrugated chip-breaker edge, they rapidly plow through alloy steels and cast iron. As a direct OEM manufacturer, we produce both Metric and Imperial sizes, offering complete customization for cutting diameters, overall reaches, and brand packaging.
Key Technical Advantages
- Premium HSS-Co Substrate: The addition of Cobalt drastically increases the tool's "red hardness" (ability to maintain a sharp edge at high temperatures) and provides superior shock resistance compared to solid carbide, preventing catastrophic failure in heavy interrupted cuts.
- Corrugated Chip-Breaker Profile: The wavy cutting edge fractures chips into small, easily evacuated pieces. This drastically reduces cutting forces and spindle vibration, allowing for deeper, more aggressive cuts.
- TiN (Titanium Nitride) Coating: The distinct golden TiN coating lowers the coefficient of friction and provides excellent surface hardness, significantly extending tool life and reducing edge buildup.
- High Cost-Performance Ratio: Offers an unbeatable balance of durability and price. Ideal for large-volume roughing jobs where the brittleness or high cost of solid carbide is not justified.
- Comprehensive OEM Capabilities: Whether your market demands standard Metric (D6-D32) or Imperial sizes (like 3/4"), or requires specific Weldon flats on the shank for extreme holding power, our factory manufactures exactly to your blueprints.
