4-Flute Carbide TiSiN Flat End Mill | CNC Milling Cutter
4-Flute Carbide TiSiN Flat End Mill | CNC Milling Cutter
4-Flute Tungsten Carbide Flat End Mill with TiSiN Nano Coating
Engineered for high-performance CNC machining, this tungsten carbide flat end mill delivers exceptional cutting precision across hardened steel, alloys, molds, and hard workpieces. Featuring a premium TiSiN (Titanium Silicon Nitride) nano coating and a precision-ground 4-flute spiral design, this end mill is built to outlast standard tooling while maintaining superior surface finishes — even at elevated cutting speeds.
Made in Mainland China.
Key Features
- Exceptional Cutting Hardness: Constructed from solid carbide material, offering outstanding hardness and high-temperature resistance for stable cutting of hardened steel, alloys, and tough workpieces — effectively extending tool service life.
- Anti-Wear TiSiN Nano Coating: The cutting edge is coated with a premium TiSiN nano coating that reduces the friction coefficient during processing, improves overall wear resistance, and allows higher cutting speeds — reducing long-term tooling costs.
- Efficient 4-Flute Chip Removal: The precision-ground 4-flute spiral design guides chips smoothly out of the cutting zone, prevents chip clogging, reduces vibration, and delivers a high-quality machined surface finish — no extra polishing required.
- High-Precision Ground Shank: Ultra-low runout error achieved through fine-grinding of the shank ensures compatibility with most CNC machines and milling equipment, guaranteeing processing accuracy and slip-free high-speed operation.

Frequently Asked Questions
Q: What materials can this carbide flat end mill cut?
A: This 4-flute tungsten carbide end mill is designed for cutting hardened steel, stainless steel, alloys, mold steel, and other hard workpieces commonly encountered in CNC machining and precision engineering applications.
Q: What is TiSiN nano coating and why does it matter?
A: TiSiN (Titanium Silicon Nitride) is an advanced nano coating applied to the cutting edge of the end mill. It significantly reduces friction during cutting, improves wear resistance, enables higher cutting speeds, and extends the overall service life of the tool — lowering your long-term tooling costs.
Q: Is this end mill compatible with standard CNC milling machines?
A: Yes. The shank is precision-ground to an ultra-low runout tolerance, making it compatible with most CNC machining centers and milling equipment. Its high-precision fit ensures stable, slip-free performance during high-speed operations.
Q: How many flutes does this end mill have, and why does that matter?
A: This end mill features a 4-flute spiral design. The 4-flute configuration provides excellent chip evacuation, reduced cutting vibration, and a superior surface finish compared to 2-flute designs — making it ideal for finishing passes and hard material milling.
