| 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. |
HNCarbide provides carbide end mill cutter tools for a wide range of materials: carbon steel, alloy steel, stainless steel, cast iron, tool steel, hardened steel, aluminum and non-ferrous alloys. Different series are optimized for specific hardness ranges (e.g. 55HRC, 60HRC, 65HRC) and applications such as roughing, semi-finishing and finishing. By choosing the right grade, geometry and coating, one end mill carbide cutter can deliver stable performance on multiple materials in your CNC shop.
Flute number is directly related to chip evacuation and rigidity. 2-flute carbide end mill cutter designs are ideal for aluminum and non-ferrous materials where larger chip pockets are needed. 3-flute and 4-flute end mill carbide cutter tools offer higher rigidity and more cutting edges per revolution, which is better for steel, stainless steel and hardened steel.

| Nano-Blue | Blue surface layer: may contain AlCrN (aluminium-chromium nitride) or TiSiN (titanium–silicon nitride); the blue colour comes from nano-structured interference. Nanomultilayer structure: alternating layers such as TiN/AlN (individual layer thickness ＜50 nm) to increase hardness and thermal stability. | Hardness: 3000–4000 HV (nano-indentation). Friction coefficient: 0.1–0.3 (lower when combined with DLC). Heat resistance: stable up to 1000°C (oxidation starts above 800°C). Adhesion strength: ≥70 N (critical load in scratch test). Surface roughness: Ra ＜0.05 μm (after polishing). | Blue appearance: achieved by nano-optical thin-film design, and can serve as wear indicator (colour change shows coating loss). Self-lubricating: some Si- or WC-containing nanocoatings can form a silica-based lubricating layer at high temperature. | Recommended workpiece materials High-hardness steels (HRC＞50, such as mould steel, bearing steel). High-temperature alloys (nickel-based / titanium alloys, relying on coating heat resistance). Non-ferrous metals (aluminium and copper alloys, requiring low-friction coating to prevent built-up edge). Composites (CFRP, avoiding adverse reactions between coating and fibres). Typical application fields Aerospace: machining turbine-blade dovetails, milling titanium-alloy structural parts. Automotive moulds: high-precision cavity milling, balancing efficiency and surface quality. Medical devices: micro-machining of cobalt-chromium artificial joints. |
Our Corner Radius End Mill Solid Carbide drawings clearly show key Corner Radius End Mill Solid Carbide dimensions such as diameter, radius, flute length and overall length. This helps you confirm the right Corner Radius End Mill Solid Carbide sizes for your CNC setup and machining depth before ordering.
HNCarbide provides carbide end mill cutter tools for a wide range of materials: carbon steel, alloy steel, stainless steel, cast iron, tool steel, hardened steel, aluminum and non-ferrous alloys. Different series are optimized for specific hardness ranges (e.g. 55HRC, 60HRC, 65HRC) and applications such as roughing, semi-finishing and finishing. By choosing the right grade, geometry and coating, one end mill carbide cutter can deliver stable performance on multiple materials in your CNC shop.
Flute number is directly related to chip evacuation and rigidity. 2-flute carbide end mill cutter designs are ideal for aluminum and non-ferrous materials where larger chip pockets are needed. 3-flute and 4-flute end mill carbide cutter tools offer higher rigidity and more cutting edges per revolution, which is better for steel, stainless steel and hardened steel. For slotting or roughing you may use fewer flutes; for finishing and side milling, higher flute counts often provide better surface finish.
For distributors and regular customers, we can offer a structured carbide end mill cutter price list based on series, coating and order quantity. For new users, carbide end mill cutter price is usually quoted according to size range, material grade and customization level. Most standard items have low MOQ and we can provide sample pieces for testing before bulk order, helping you verify performance in your own CNC machining conditions.

A corner radius solid carbide end mill cutter has reinforced edges that reduce chipping and extend tool life, especially in hard materials. It also helps improve fatigue strength and surface transition in pockets and shoulders, making it more stable than a standard square end in many HRC65 applications.
This tool is commonly used in mold and die machining, precision tooling, and high-accuracy components with shoulders, pockets, and 3D edges. It is ideal wherever a durable radius end mill is required to achieve good surface finish and tight tolerances.
Recommended parameters depend on material hardness, machine rigidity, and toolholder type. As a guideline, start with conservative values for solid carbide end mill cutting speed, use sufficient coolant or air blow, and then fine-tune feeds and speeds based on tool wear and surface finish.
