| TiSiN | Ti (titanium): main element, forms TiN nanocrystalline phase. Si (silicon): usually 6–10%, forms amorphous Si₃N₄ phase, refines grains and increases hardness. N (nitrogen): combines with Ti and Si to form a composite structure. | Colour: TiSiN coatings usually appear bronze or dark grey-bronze; exact colour depends on Si content, deposition process (such as PVD) and thickness (1–4 μm). Hardness: 34–42 GPa (≈3400–4200 HV). Friction coefficient: 0.3–0.6 (against steel). Temperature resistance: 1000–1200°C (oxidation resistance). Coating thickness: 1–5 μm (typically 2–3 μm). Deposition temperature: 200–400°C (suitable for carbide tools). | Ultra-high hardness: amorphous Si₃N₄ phase suppresses dislocation movement, giving much higher hardness than TiN (~23 GPa) and TiAlN (~35 GPa). High-temperature stability: suitable for dry cutting and high-speed machining (e.g. quenched steels HRC 60+). Anti-adhesion: reduces built-up edge when machining aluminium alloys, stainless steels and other sticky materials. | Tool coatings: drills, mills (especially suitable for PCB routers, tool life increased by 2–3 times). High-speed cutting of quenched steels, titanium alloys and high-nickel alloys. Mould strengthening: die-casting moulds and stamping dies, improving wear resistance. Industrial parts: piston rings and other high-temperature wear parts. |

Large-volume orders are reinforced with double-wall cardboard boxes or wooden crates to maximize safety during international shipping.
We collaborate with reliable logistics partners to ensure goods are delivered quickly and securely to their destination via air freight, sea freight, or express courier.
A ball end mill has a rounded cutting edge for machining 3D contours, cavities and curved surfaces. It is ideal for moulds, dies and complex parts where sharp corners are not required but smooth transitions and fine surface finish are important.
A 2 flute ball end mill provides more space for chip evacuation, making it a good choice for softer materials and slotting or roughing operations. A 4-flute ball end mill offers stronger cutting edges and allows higher feed rates, giving better productivity and surface finish in stable steel machining.
Standard ball end mill sizes include small diameters such as 1mm ball end mill, 2mm ball end mill, 3mm ball end mill, and popular tools like 4mm ball end mill, 6mm ball end mill, 8mm ball end mill and 10mm ball end mill. Larger diameters, for example 18mm ball end mill, can be supplied for heavy milling and efficient roughing.
