In processing ≤ HRC65 alloy steel, hardened steel, tool steel, and cast iron 600 At this time, tool stability, wear resistance, and cutting efficiency are the top concerns for every workshop. Materials such as quenched steel and die steel have high hardness and significant cutting resistance, placing considerable demands on the tool’s substrate, geometric structure, and process stability.
The tungsten steel introduced today 65 degree 4 Flat-end milling cutter Made from high-quality, ultra-fine-grain bar stock and formed using dry bag isostatic pressing, combined with the stringent process controls of the Lizhou HuaTuo series, this is a high-performance milling cutter that delivers stable cutting performance specifically tailored for high-hardness materials. It is suitable for a wide variety of applications. CNC Processing scenario.
1. Uses ultra-fine-grain bar stock, suitable for ≤ HRC65 Hardness material
Machining high-hardness steels places extremely high demands on the tool’s hardness, toughness, and wear resistance. This series of end mills features:
Ultrafine-grain cemented carbide
Dry Bag Isostatic Pressing Process
The bar stock has a denser microstructure and higher toughness, enabling the tool to... HRC65 It still exhibits excellent chipping resistance and stable tool life on high-hardness materials.
Applicable scope includes:
HRC60 – 65 Quenched steel
Various types of mold steels and tool steels
High-hardness alloy steel
Cast iron 600 Ductile iron
2. Four-blade cutter head design, featuring high rigidity, minimal vibration, and superior surface finish.
Four-flute flat-end tools offer superior structural rigidity and are particularly well-suited for stable cutting of hard materials.
The tool has better overall rigidity and is less likely to experience chatter.
The cutting path is smooth, and the dimensions are more accurate.
Better surface roughness
More suitable for high-speed machining
Compared to two-blade and three-blade designs, a four-blade cutter head delivers more stable performance on hard steel and is particularly well-suited for:
Side machining
Step machining
Roughing and Semi-Finishing for Right-Angle Slots
Mold steel planar machining
Three, You Groove + Double-edged flute design ensures smooth chip removal and more stable machining.
✔ You Slot design (large chip evacuation space)
The chips produced by hard steel are short and brittle, but the cutting resistance is high. If chip removal is not smooth, it will accelerate tool wear. You The groove design provides greater chip evacuation space, enabling chips to be quickly removed: reducing machining heat generation, preventing secondary friction of chips, extending tool life, and maintaining smooth cutting performance.
✔ Double-edged belt structure (for more stable guidance)
When machining side walls on hardened steel, a double-edged cutting edge can improve straightness and dimensional accuracy, while reducing issues such as "tool wandering, side-wall tool marks, and step marks."
4. Flat-head design, compatible with a variety of... CNC Processing requirements
Flat-end milling cutters are the most widely used and are almost indispensable tools in machining workshops:
Side cutting (rough machining of external shape) + Semi-finishing)
Step machining (sharp right angles)
Right-angle groove machining
Planar finishing
Mold contour machining
For HRC65 Despite being made of a hard material, this tool still maintains excellent dimensional consistency and cutting stability, making it a highly “worry-free” general-purpose tool for machining high-hardness steels.
5. Complete range of specifications, supports non-standard customization.
The LIZHOU HUATUO series offers:
Complete standard size
Customized special blade length and handle length
Special blade angle
Special coating
Extended neck, slender handle, and deep-groove blade structures
OEM/ODM
Whether it's deep cavity machining, complex structures, or special mold dimensions, we can provide customized tooling solutions.
Six: Why more and more processing plants are choosing Lizhou. 65 degree 4 Flat-end face milling cutter?
From the customer's perspective, its advantages are very straightforward:
In HRC65 Still stable and wear-resistant on hard materials.
Smooth cutting, not easy to chip the blade.
The machined surface is smooth, reducing the need for secondary polishing.
Longer tool life, reducing the number of tool changes.
Good chip removal, no chip clogging, and no tool burning.
No preference for machine tools—both high-speed machines and machining centers are suitable.
Complete specifications and customizable, with strong adaptability.
It’s a solid steel end mill that is truly “stable, worry-free, and durable.”
