The HS(200) 2 Flute Ball Nose End Mill uses 0.2 μm ultra-fine grain carbide with an AlTiCrSiN multi-element PVD coating. Designed for high-speed machining of hardened and mold steel up to 65 HRC, it also suits stainless steel, titanium alloys, nickel-based superalloys, and precision finishing.
The HS(200) 2 Flute Ball Nose End Mill is designed for high-speed machining of high-hardness and difficult-to-machine materials.
Its 0.2 μm ultra-fine grain carbide substrate provides a fine and stable cutting edge for demanding milling applications.
The tool is combined with an AlTiCrSiN multi-element PVD coating developed for elevated cutting temperatures.
The coating delivers high-temperature performance above approximately 1100°C, making the HS(200) suitable for high-speed, dry, and semi-dry cutting.
The ball nose geometry also supports applications where surface finish and contour accuracy are important.
Key Features & Benefits
0.2 μm Ultra-Fine Grain Carbide
The HS(200) uses 0.2 μm ultra-fine grain carbide, providing a fine cutting edge for precision milling.
Its substrate is designed to support edge stability and wear resistance during high-speed machining of hardened materials.
AlTiCrSiN Multi-Element PVD Coating
The AlTiCrSiN PVD coating provides high hardness and strong resistance to elevated cutting temperatures.
Its high-temperature performance above approximately 1100°C makes it suitable for demanding high-speed and dry machining conditions.
Designed for Hardened Steel up to 65 HRC
The HS(200) is developed for hardened steel and mold steel up to 65 HRC.
This makes it suitable for hard milling applications where conventional general-purpose tools may not provide sufficient wear resistance or thermal performance.
High-Speed, Dry, and Semi-Dry Machining
The HS(200) is particularly suited to high-speed dry and semi-dry cutting.
It can also be used with coolant when the machining process or workpiece requires coolant-assisted cutting.
Designed for Surface Finish
The ball nose profile is suitable for 3D contouring and finishing operations where surface quality is important.
The HS(200) is a practical choice for applications requiring a balance between high-hardness machining and a controlled surface finish.
Machining Challenges the HS(200) Helps Solve
Machining Steel Above 60 HRC
High-hardness steel places significant mechanical and thermal stress on the cutting edge.
With a 0.2 μm ultra-fine carbide substrate and AlTiCrSiN coating, the HS(200) is designed for machining hardened materials up to 65 HRC.
Cutting Heat During High-Speed Machining
High spindle speeds can increase cutting temperature, especially when machining hardened steel.
The AlTiCrSiN coating is designed to withstand elevated temperatures and support stable cutting performance above approximately 1100°C.
Maintaining Surface Quality
Finishing hardened materials requires controlled cutting action to achieve the required surface quality.
The ball nose geometry is suited to contour and finishing operations where surface finish is a key requirement.
Machining Difficult Alloys
Stainless steel, titanium alloys, and nickel-based superalloys can generate high cutting temperatures and accelerate tool wear.
The HS(200) provides a high-hardness coated option for demanding applications involving these materials.
