Combination Carbide Internal End Mill Overview
This 4-flute solid carbide combination end mill integrates radius-forming and chamfering geometry into one tool for components that require both rounded transitions and edge chamfers. The combined cutting profile allows compatible radius and chamfer features to be machined within one tooling setup, making the cutter suitable for mold cavities, precision mechanical components, valve bodies and other parts with multi-feature edge geometry. The 4-flute solid carbide construction provides a rigid cutting platform, while radius, chamfer angle, tool dimensions and coating can be selected according to the workpiece material and component drawing.

Combination Radius & Chamfer Geometry
Radius-Forming Profile
The formed cutting section produces the specified radius or rounded transition according to the component geometry and required profile.
Integrated Chamfering Edge
The chamfering section can be configured for 30°, 45°, 60° or drawing-defined edge geometry where radius and chamfer features are required together.
Single-Tool Combination Machining
Combining the radius and chamfer features in one cutter can reduce separate tooling operations when the component geometry and machining sequence are suitable.
Application-Specific Advantages
Combined Operations
Radius forming and chamfering can be integrated into one application-specific cutting profile.
4-Flute Geometry
Four cutting edges support repeated engagement during combined profile machining.
Flexible Chamfer Geometry
30°, 45° and 60° chamfer configurations cover common edge-forming requirements.
Custom Combination Profile
Radius, chamfer angle, feature position, diameter and length can be reviewed from drawings.

Tool Nomenclature & Dimensions
Reference dimensions for the 4-flute solid carbide combination corner-rounding and chamfering end mill. The radius, chamfer geometry and their axial relationship should be confirmed together because both cutting features are integrated into one tool. A component drawing is recommended for non-standard combination profiles.

Combination Machining Guidance
- Profile Matching: Confirm both the radius and chamfer dimensions from the component drawing before selecting or manufacturing the cutter.
- Axial Position: The relationship between the radius and chamfer features depends on accurate cutter positioning and the axial spacing built into the tool profile.
- Toolholding: Use a low-runout precision holder and the shortest practical overhang to maintain profile consistency.
- Material Configuration: Select cutting-edge preparation and coating according to the actual steel, stainless, aluminum or plastic grade.
- Custom Tools: For non-standard combination profiles, provide a component drawing showing the radius, chamfer angle, chamfer width and axial feature positions.
Combination Internal End Mill Customization
Radius size, chamfer angle, chamfer width, combination-profile geometry, feature position, cutter dimensions, shank configuration, overall length, cutting-edge preparation and coating can be configured according to the component drawing and machining application. Standard 4-flute configurations cover R1–R6 mm radius sizes, while 30°, 45° and 60° chamfer angles are available as reference options. Non-standard combination profiles can be reviewed according to the workpiece material, required radius-to-chamfer relationship, machining depth, feature clearance and dimensional requirements.
| PARAMETER | MANUFACTURING CAPABILITIES |
|---|---|
| Radius Size | Current standard 4-flute configurations include R1, R1.5, R2, R2.5, R3, R4, R5 and R6 mm. Smaller or non-standard radii can be reviewed separately according to the required profile and flute configuration. |
| Chamfer Angle | 30°, 45° and 60° chamfer angles are available as reference configurations. Non-standard angles can be reviewed according to the component drawing and required edge geometry. |
| Chamfer Width | Chamfer width can be configured according to the finished component requirement, cutter diameter and available profile length. |
| Combination Profile | Radius-forming and chamfering sections can be integrated into one cutting profile. The relationship between both features should be defined from the component drawing for accurate tool design. |
| Feature Position & Spacing | Axial position and spacing between the radius and chamfer features can be reviewed according to the workpiece geometry, machining depth and required transition position. |
| Flute Count | Standard 4-flute solid carbide configuration for combination profile machining. |
| Cutter Diameter | Reference product diameter range is Ø3–Ø16 mm. Non-standard cutter dimensions can be reviewed according to the required radius, chamfer geometry and component clearance. |
| Helix Geometry | A 38°–42° variable-helix configuration is available as a reference design. Final helix geometry can be selected according to workpiece material, chip evacuation and cutting engagement. |
| Konfigurasi Shank | Precision cylindrical shank dimensions can be selected according to tool size, holder compatibility, clamping length and required machining reach. |
| Panjang Keseluruhan | Standard and drawing-defined overall lengths can be reviewed according to machining depth, toolholder clearance and required tool rigidity. |
| Cutting-Edge Preparation | Radius-forming edges, chamfering edges, relief geometry and edge preparation can be matched to the workpiece material, cutting load and required profile finish. |
| Coating Selection | TiAlN, AlTiN or DLC configurations can be reviewed according to workpiece material and machining conditions. Steel and stainless-steel applications normally require a different coating strategy from aluminum and other non-ferrous materials. |
| Bahan Benda Kerja | Configurations can be reviewed for mold steel, stainless steel, aluminum alloys and selected engineering plastics. Cutting geometry and coating should be matched to the actual material rather than using one universal configuration. |
| Machining Application | Suitable configurations can be developed for combined radius forming, edge chamfering, profile finishing, cavity-edge machining and other multi-feature operations. |
| Profile & Dimensional Tolerance | Drawing-defined requirements can be reviewed for radius geometry, chamfer angle, chamfer width, feature spacing, cutter diameter, shank diameter, overall length and tool runout. |
