| 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.

HNCarbide HRC65 4 flute blue nano coated corner radius carbide end mill cutter is designed for high-speed machining of hardened steels, alloy steels and stainless steels up to 65HRC. Manufactured from ultra-fine grain solid carbide end mill cutter substrate and finished on advanced CNC grinding equipment, it provides excellent wear resistance, edge stability and dimensional accuracy at high cutting speeds.
The corner radius geometry on this 4 flute end mill carbide cutter reduces edge chipping, improves tool strength and helps achieve a smooth surface finish on shoulders, pockets and 3D profiles. Blue nano coating enhances heat resistance and anti-adhesion behaviour, keeping cutting edges sharp and chips flowing in continuous or light interrupted cuts. As a professional china cnc carbide end mill cutter supplier, HNCarbide offers this tungsten carbide end mill cutter in a wide range of metric and inch sizes, with optional flute length, shank style and coating for different CNC setups.
Grade HN44F is made from submicron WC powder, some special additives added.
It’s suitable for making drills and end mills, especially for machining steel,Al-based alloys and Ti-basedalloys.

| 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.

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.

In modern CNC workshops, the carbide end mill cutter has become a core tool for achieving high productivity, tight tolerances and excellent surface finish. Compared with traditional HSS tools, solid carbide end mill cutter solutions run at higher speeds, last longer and deliver more consistent results, especially on stainless steel, hardened steel and other difficult materials.
This article explains what a carbide end mill cutter is, the main types you will see in a catalog, how to read a carbide end mill cutter price list, and practical tips for choosing the right tool for your CNC operations.
A carbide end mill cutter is a rotary cutting tool used on milling machines and machining centers to remove material from a workpiece. It is made from tungsten carbide end mill cutter substrate, which offers:
Much higher hardness and wear resistance than HSS
Better performance at high cutting temperatures
More stable dimensional accuracy at high speeds
Because of these properties, carbide end mill cutter tools are widely used in mould and die making, automotive parts, aerospace components and precision engineering. A high-quality end mill carbide cutter allows you to increase spindle speed and feed rate without sacrificing tool life or surface finish.
Flat carbide end mill cutter tools are the most common choice for:
Slotting and side milling
Shoulder milling
General roughing and finishing
They create a flat bottom and sharp edges, which are ideal for pockets and steps.
Ball nose tungsten carbide end mill cutter designs are used for:
3D contouring and free-form surfaces
Mould cavities and die profiles
Finishing complex shapes
The spherical tip allows smooth transitions on curved surfaces and reduces the risk of leaving sharp marks.
Corner radius end mill cutter carbide tools combine a flat bottom with a small radius at the corner. Advantages include:
Less edge chipping in hardened steel
Longer tool life in heavy cutting
Better surface integrity on shoulders and pockets
They are popular for mould inserts and precision components where durability is important.
Start from the material:
Carbon and alloy steels
Stainless steel
Cast iron
Aluminum and non-ferrous alloys
Hardened steels up to 65 HRC
Match the tool grade and coating to the hardness range. A high-performance solid carbide end mill cutter for 60–65 HRC will not be economically ideal for soft steels, and a general-purpose tool may fail quickly in hardened steel.
Flute count has a strong impact on chip evacuation and rigidity:
2 flutes: more chip space, ideal for aluminum and non-ferrous materials
3 flutes: good balance between chip evacuation and strength
4 flutes and above: stronger core, better for steel, stainless and hard materials
Choose flute geometry according to operation: roughing, semi-finishing or finishing.
A good tungsten carbide end mill cutter combines:
Fine-grain carbide substrate (hardness + toughness)
PVD or nano coating (heat resistance + low friction)
Coating helps control heat and chip flow, especially in high-speed or dry machining.
When comparing suppliers, you will usually receive a carbide end mill cutter price list. Don’t only look at the lowest carbide end mill cutter price per piece. Also consider:
Substrate grade and coating type
Tolerance and quality level
Available stock and delivery time
Technical support and customization options
A well-designed china cnc carbide end mill cutter might cost slightly more, but if it offers longer tool life and higher cutting data, your cost per part will be lower.
Many users are familiar with international brands such as niagara cutter carbide end mill solutions. As a professional china cnc carbide end mill cutter manufacturer, HNCarbide focuses on:
Fine-grain solid carbide substrates
Advanced CNC grinding technology
Stable batch-to-batch quality
Flexible customization and reasonable pricing
This allows customers to build a tool library that balances performance and cost, without sacrificing reliability in demanding CNC applications.
To maximize the value of your carbide end mill cutter tools, keep these points in mind:
Use high-quality tool holders to minimize runout
Keep tool overhang as short as possible
Adjust feeds and speeds according to material hardness and tool diameter
Check wear patterns to fine-tune cutting parameters
Use proper coolant or air blast to remove chips from the cutting zone
Even the best solid carbide end mill cutter cannot perform well in poor setup conditions, so machine rigidity and clamping are just as important as tool selection.
