HRC62 4 Flute ultra micro grain carbide end mills DESCRIPTION ▼
HRC62 4 Flute ultra micro grain carbide end mills are known for their excellent hardness and wear resistance. This makes them suitable for machining hard materials such as stainless steel, cast iron, and high temperature alloys. The HRC62 hardness ensures extended tool life and consistent cutting performance.
The HRC62 4 Flute ultra micro grain carbide end mill is very tough, resists wear and offers high cutting performance.
HRC62 4 Flute ultra micro grain carbide end mills Features：
These ultra micro grain carbide end mills were ground free again to be able to mill deeper and still have good stability.
Superhard Composite coating for high cutting speeds.
Without corner radius (sharp edges), the 4-flute carbide mill cutter design is suitable for both roughing and finishing operation
Hard carbide mill cutter for hardened and difficult-to-machine steels.
Optimized cutting-edge geometry ensures high precision and excellent chip evacuation, reducing the risk of tool breakage and increasing machining efficiency.

● Carbide micro end mills are designed for high-speed cutting of hardened steel (up to 62HRC)
● Carbide micro end mills with excellent workpiece surface finish.
ultra micro grain carbide end mills Application:
S136, SKD11 DC53, 440C, D2, Cr12MoV, H13, 42CrMoA, ASP30 etc.
High quality and stable milling performance with carbide ball nose end mill life by optimized design.
ultra micro grain carbide end mills features:
Unique tool structure, combined with an optimized groove design, achieves excellent cutting performance. ball nose end mill is generally of a rounded, ball-shaped tip with a radius equal to the radius of the tools, which provides successive curved cutting edges.
When machining intricate 3D shapes —such as rounded edges, complex geometries, etc. These ball nose end mills are widely used in mold and die-making, aerospace, automotive, and medical industries.
Ball bottom produces a uniform finish and smooth surface on curved contours for finishing operations and minimizes additional machining
Special surface post-treatment effectively reduces friction, chip removal more smooth, better surface quality.
Versatile Material Compatibility One of the significant advantages of using a ball nose end mill is its ability to machine a wide range of materials like steel, aluminum, plastics, and even exotic metals, enabling them versatility for various machining tasks.
Quality Control
Product quality assurance is the key to a business. Baiyang Micro Diameter Carbide Mill Cutter quality is manifested in the following aspects：
Dimensional Inspection: All our micro carbide mill cutters are measured according to strict tolerances to ensure compliance with international standards.
Hardness Testing: We have our own test CNC machines. The hardness of the micro carbide mill cutter is tested to verify that they meet the required standards before shipment
Performance Testing: Micro carbide mill cutter undergo performance tests to assess cutting efficiency, tool life, and surface finish quality.
