4 Flute Carbide End Mill Overview
UN 4 flute carbide end mill combines four cutting edges with a strong solid carbide core. This design provides good rigidity, résistance à l'usure, and stable cutting performance when machining steel, acier inoxydable, acier allié, et acier à outils.
Its flat or square cutting end produces flat-bottom features, straight side walls, mesures, machines à sous, et épaules carrées. Entre-temps, 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. Par conséquent, it works well for flat-bottom slots, poches, mesures, profils, et épaules carrées.
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. Donc, the cutter can support vertical plunging, ramp entry, helical interpolation, side entry, and light slotting.
The suitable entry method depends on the cutting diameter, longueur de flûte, matériau de la pièce à usiner, rigidité de la machine, et paramètres de coupe. 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
La nuance carbure, revêtement, and cutting geometry should match the workpiece material and hardness. The following table provides general selection guidance.
| Matériau de la pièce | Typical Workpiece Hardness | Recommended Coating | Applications courantes |
|---|---|---|---|
| General Steel | Jusqu'au HRC 45 | TiN or TiAlN | Fraisage latéral, fraisage de profil, et finition |
| Acier inoxydable | Jusqu'au HRC 45 | TiAlN or AlTiN | Fraisage de profil, semi-finition, et fraisage latéral contrôlé |
| Acier allié | Jusqu'au HRC 50 | TiAlN or AlTiN | Finition, fraisage de contours, et usinage CNC général |
| Acier à outils / Acier pré-trempé | Jusqu'au HRC 55 | AlTiN or TiSiN | Composants du moule, profils, et finition de précision |
| Acier trempé / Die Steel | Jusqu'au 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, conditions du liquide de refroidissement, rigidité de la machine, tenue de l'outil, et durée de vie requise de l'outil.
Stainless steel can generate heat and work hardening. Donc, 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.
Options de spécification
We supply common metric sizes and can also evaluate inch-size and custom requirements.
| Spécification | Available Range or Option |

| Custom Dimensions | Available according to requirements or drawings |
Common shank diameters include 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, et 20 mm. Common overall lengths include 50 mm, 60 mm, 75 mm, et 100 mm.
Actual availability depends on the complete combination of cutting diameter, longueur de flûte, diamètre de la tige, revêtement, et géométrie. 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.
Géométrie de coupe centrale, corner chamfers, corner radii, revêtements, and other non-standard features can also be produced according to your drawing or machining requirements.
A longer tool may have lower rigidity. Donc, the cutting depth, atteindre, 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, fraisage de profil, fraisage de contours, finition, semi-finition, square-shoulder machining, and light slotting.
Its center-cutting design also supports plunging, rampe, and helical entry under suitable machining conditions.
Four flutes provide good rigidity and surface stability. Cependant, they offer less space for chip evacuation than a two-flute design. Donc, deep slots, aluminium, and other chip-intensive operations may require a lower flute count.

Aluminum machining considerations are explained in sont 4 fraises à flûte bonnes pour l'aluminium.
For finishing-focused flute selection, lire 4 flûte contre 6 fraise à cannelure.
UN 6 fraise en bout de carbure de cannelure may suit lighter finishing cuts that require more cutting edges.
Heavy material removal is better handled with dedicated fraises d'ébauche.
Cutting Performance and Quality
Solid carbide provides high hardness, résistance à l'usure, and cutting-edge stability. Entre-temps, the four-flute design creates a strong core for stable machining of steel and stainless steel.
This combination can improve cutting rigidity, qualité de surface, cohérence dimensionnelle, and tool life under suitable machining conditions.
Cependant, final performance also depends on the tool geometry, revêtement, titulaire, méthode de refroidissement, état de la machine, et paramètres de coupe.
Dimensional and Runout Inspection
We inspect key dimensions, arêtes de coupe, and runout before shipment to help maintain consistent product quality.

Foire aux questions
What materials can a 4 flute carbide end mill machine?
It can machine general steel, acier inoxydable, acier allié, acier à outils, acier pré-trempé, and selected hardened steels.
The suitable carbide grade, revêtement, and geometry depend on the workpiece material and hardness.
Is this 4 flute square end mill center cutting?
Oui. Its center-cutting geometry allows the cutting edges to extend across the tool center.
Donc, it can support plunging, rampe, 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, liquide de refroidissement, profondeur de coupe, and tool life requirements.
