Precision Milling Cutters,Cutting Tools for CNC Machining Every Material
Our current factory range includes several configurations if you need an end mill for stainless steel, including flat, ball nose, and corner radius designs. These tools use solid carbide / tungsten carbide substrates with nano coating and cover both standard specifications and drawing-based custom requirements.
Specification Options
Representative Standard Ranges
Custom Sizes Available on Request
| Tool Type | Flutes | Representative Standard Range |
|---|---|---|
| Flat End Mill | 4F | Cutting diameter approx. 1–20 mm; flute length approx. 3–75 mm; OAL approx. 50–150 mm |
| Ball Nose End Mill | 2F | Ball radius approx. R0.5–R10; OAL approx. 50–150 mm |
| Corner Radius End Mill | 4F | Cutting diameter approx. 1–12 mm; standard radius examples include R0.2, R0.5 and R1; OAL approx. 50–100 mm |
These are representative standard specifications, not the complete manufacturing range or a statement of stock availability. If your required size falls outside these examples, we can review the cutting diameter, flute length, shank diameter, overall length, ball radius, or corner radius according to your dimensions or drawing.
Applications and Selection
The cutter geometry should match the feature being machined. Therefore, our current stainless steel end mill specifications cover three main configurations.
4-Flute Flat End Mills for Stainless Steel
The 4-flute flat configuration uses a solid carbide substrate with nano coating and suits machining features that require a flat cutting end.
Typical applications include:
- Flat surface milling
- Side milling
- Shoulder machining
- Flat-bottom machining
- Profiling
Representative factory specifications include cutting diameters from approximately 1 mm to 20 mm, with multiple flute-length and overall-length combinations.
For the complete product range and additional specifications, see our Flat End Mill.
2-Flute Ball Nose End Mills for Stainless Steel
The 2-flute ball nose configuration uses a rounded cutting end for curved or three-dimensional workpiece features.
Typical applications include:
- Curved surface machining
- 3D contouring
- Mold and cavity surfaces
- Profile finishing
- Complex surface machining
Representative standard specifications include ball radii from approximately R0.5 to R10 and overall lengths from approximately 50 mm to 150 mm.
For the complete product range, see our Ball Nose End Mills.
4-Flute Corner Radius End Mills for Stainless Steel
The 4-flute corner radius configuration combines a flat cutting end with an R-radius at the cutter corner.
For example, this geometry can suit workpiece features that require a specified corner radius.
Typical applications include:
- R-corner machining
- Pocket features with corner radii
- Side and bottom machining
- Profile machining
Representative specifications include cutting diameters from approximately 1 mm to 12 mm, with standard radius examples such as R0.2, R0.5, and R1.
For additional radius-type product options, see our Bull Nose End Mill.

Key Features
Solid Carbide Construction
The standard stainless steel end mills shown on this page use a solid carbide / tungsten carbide substrate.
Solid carbide provides a rigid tool body for CNC milling and supports the flat, ball nose, and corner radius geometries in the current range.
In addition, you can view our broader carbide tooling range on the Carbide End Mill Cutter page.
Nano-Coated Cutting Edges
The current factory specifications use nano coating for these stainless steel end mill configurations.
Factory product information describes the tools as sharp, wear-resistant, and durable. If your application requires a specific coating system, include that requirement in your inquiry so we can review it together with the workpiece material and tool specification.
Multiple End Geometries
The current standard range includes:
- Flat end geometry
- Ball nose geometry
- Corner radius geometry
These geometries cover flat, curved, and radius-type workpiece features while keeping each cutter type clearly separated by application.
Standard and Custom Dimensions
Standard specifications include multiple combinations of cutting diameter, flute length, shank diameter, overall length, ball radius, and corner radius.
However, the representative ranges shown above do not define the full manufacturing range. If you need another size, send us the required dimensions or drawing for review.
Custom End Mills for Stainless Steel
Standard specifications cover many common applications. For non-standard requirements, our factory can review tool dimensions and geometry according to the machining application, customer specifications, or drawings.
Custom Options
Key dimensions, radius features, lengths, and other drawing-defined details can vary by application. Therefore, we confirm the final specification according to the actual requirement before production.
What to Provide for Tool Evaluation
For quotation or technical review, please send the workpiece material, machining requirement, key tool dimensions, and a drawing if available. If you currently have a machining problem, you may also include it for reference.
Frequently Asked Questions
What types of end mills do you offer for stainless steel?
The current standard range includes 4-flute flat end mills, 2-flute ball nose end mills, and 4-flute corner radius end mills. The appropriate cutter type depends on the workpiece feature and machining operation.
Are your stainless steel end mills made from solid carbide?
Yes. The standard products shown on this page use a solid carbide / tungsten carbide substrate with nano coating.
What standard flute configurations are available?
The currently confirmed standard configurations are:
- Flat End Mill — 4 Flutes
- Ball Nose End Mill — 2 Flutes
- Corner Radius End Mill — 4 Flutes
These configurations match the current factory standard specifications. If you need another tool design, we can review the requirement separately.
Can you manufacture non-standard sizes or custom radii?
Yes. We can review non-standard dimensions, custom radii, and drawing-based geometries according to the application and customer requirements.
Can these end mills also machine other steel materials?
Yes. Current factory product information lists stainless steel, high-hardness steel, and general steel as applicable workpiece materials. However, the final tool selection should still match the actual material and machining requirement.
What information should I provide for a quotation?
Please send the workpiece material, machining operation, key tool dimensions, and a drawing if available. For custom applications, you can also provide the current machining problem or required result so we can review the tool requirement more accurately.
Request an End Mill for Your Stainless Steel Application
Send us your workpiece material, machining operation, required dimensions, and drawing if available. Our factory can review whether a standard 4-flute flat end mill, 2-flute ball nose end mill, 4-flute corner radius end mill, or custom solid carbide tool suits your application.
For non-standard requirements, simply provide the key dimensions and any relevant workpiece or tool drawings. We can confirm any additional information after reviewing your application.
