4 Flute Carbide End Mill Overview
А 4 flute carbide end mill combines four cutting edges with a strong solid carbide core. This design provides good rigidity, износостойкость, and stable cutting performance when machining steel, нержавеющая сталь, легированная сталь, и инструментальная сталь.
Its flat or square cutting end produces flat-bottom features, прямые боковые стенки, шаги, слоты, и квадратные плечи. Тем временем, the four-flute structure supports consistent surface quality during finishing and semi-finishing operations.

4 Flute Square End Mill Design
Flat and Square End Geometry
The flat cutting end creates a level bottom surface and a clear transition between the bottom and side wall. Как результат, it works well for flat-bottom slots, карманы, шаги, профили, и квадратные плечи.
Sharp corners, small chamfers, corner radii, and other edge preparations can be selected according to the machining application. A sharp corner creates a clear square profile, while a chamfered or radiused corner can improve cutting-edge strength.

Center-Cutting and Helix Options
The cutting edges extend across the center of the tool. Поэтому, the cutter can support vertical plunging, ramp entry, винтовая интерполяция, боковой вход, and light slotting.
The suitable entry method depends on the cutting diameter, длина канавки, материал заготовки, жесткость машины, и параметры резки. Deep plunging or heavy slotting may require a different flute count or tool geometry.
Common helix angles range from 30° to 45°. A lower helix angle can provide a stronger cutting edge, while a higher helix angle may improve cutting smoothness and surface finish.
Variable-helix designs can also be evaluated when the application requires better vibration control.
4 Flute End Mill Material and Coating Selection
Марка твердого сплава, покрытие, and cutting geometry should match the workpiece material and hardness. The following table provides general selection guidance.
| Материал заготовки | Typical Workpiece Hardness | Рекомендуемое покрытие | Common Applications |
|---|---|---|---|
| General Steel | Up to HRC 45 | TiN or TiAlN | Боковое фрезерование, профильное фрезерование, и отделка |
| Нержавеющая сталь | Up to HRC 45 | TiAlN or AlTiN | Профильное фрезерование, получистовая обработка, и контролируемое боковое фрезерование |
| Легированная сталь | Up to HRC 50 | TiAlN or AlTiN | Отделка, контурное фрезерование, и общая обработка с ЧПУ |
| Инструментальная сталь / Предварительно закаленная сталь | Up to HRC 55 | AlTiN or TiSiN | Mold components, профили, и прецизионная отделка |
| Закалённая сталь / Die Steel | Up to HRC 65 | AlTiN or TiSiN | Light finishing with application-specific geometry |
These values are general recommendations rather than fixed machining limits. Final tool selection also depends on cutting depth, coolant conditions, жесткость машины, инструмент холдинг, и требуемый срок службы инструмента.
Stainless steel can generate heat and work hardening. Поэтому, stable tool holding and controlled overhang are important.
Hardened steel may require a special carbide grade and cutting-edge preparation. Please confirm the exact workpiece hardness during the quotation process.
Параметры спецификации
We supply common metric sizes and can also evaluate inch-size and custom requirements.

Common shank diameters include 4 миллиметр, 6 миллиметр, 8 миллиметр, 10 миллиметр, 12 миллиметр, 16 миллиметр, и 20 миллиметр. Common overall lengths include 50 миллиметр, 60 миллиметр, 75 миллиметр, и 100 миллиметр.
Actual availability depends on the complete combination of cutting diameter, длина канавки, диаметр хвостовика, покрытие, и геометрия. Common sizes may support faster delivery, while special combinations may require custom production.
Long and Special-Size Options
We can provide extended flute lengths, extra-long overall lengths, long-reach or reduced-neck designs, special shank sizes, custom helix angles, and metric or inch dimensions.
Центрорежущая геометрия, corner chamfers, corner radii, покрытия, and other non-standard features can also be produced according to your drawing or machining requirements.
A longer tool may have lower rigidity. Поэтому, the cutting depth, достигать, and machining operation should be considered when selecting an extended-length end mill.
Recommended Machining Applications
The strong four-flute core and square-end geometry suit side milling, профильное фрезерование, контурное фрезерование, отделка, получистовая обработка, square-shoulder machining, and light slotting.
Its center-cutting design also supports plunging, нарастание, and helical entry under suitable machining conditions.
Four flutes provide good rigidity and surface stability. Однако, they offer less space for chip evacuation than a two-flute design. Поэтому, deep slots, алюминий, and other chip-intensive operations may require a lower flute count.

А 6 Концевая фреза из твердого сплава канавок may suit lighter finishing cuts that require more cutting edges.
Heavy material removal is better handled with dedicated черновые концевые фрезы.
Cutting Performance and Quality
Solid carbide provides high hardness, износостойкость, and cutting-edge stability. Тем временем, the four-flute design creates a strong core for stable machining of steel and stainless steel.
This combination can improve cutting rigidity, качество поверхности, постоянство размеров, and tool life under suitable machining conditions.
Однако, final performance also depends on the tool geometry, покрытие, держатель, метод подачи охлаждающей жидкости, состояние машины, и параметры резки.

Часто задаваемые вопросы
What materials can a 4 flute carbide end mill machine?
It can machine general steel, нержавеющая сталь, легированная сталь, инструментальная сталь, предварительно закаленная сталь, and selected hardened steels.
The suitable carbide grade, покрытие, and geometry depend on the workpiece material and hardness.
Is this 4 flute square end mill center cutting?
Да. Its center-cutting geometry allows the cutting edges to extend across the tool center.
Поэтому, it can support plunging, нарастание, and helical entry under suitable machining conditions.
What coating should I choose for steel or stainless steel?
TiN or TiAlN can suit general steel. TiAlN and AlTiN are common options for stainless steel and alloy steel, while AlTiN or TiSiN may suit harder tool steels.
The final selection should also consider machining speed, охлаждающая жидкость, глубина резания, and tool life requirements.
