Our TEX Series corner radius end mills are available from 1.0 mm to 12 mm in diameter, with corner radius options from R0.2 to R3.0. They offer strong versatility for everything from precise pocket features to high-load semi-finishing in stainless steel machining.
Different radius sizes support different cutting needs:
Small diameter + small radius (D1.0–D4.0 / R0.2–R1.0)
Ideal for internal pockets, step transitions, and fine profiles
→ Better accuracy and reduced burrs in SUS304 / SUS316
Medium-large diameter + larger radius (D6–D12 / R1.5–R3.0)
Increased edge strength for dynamic milling and heavy engagement
→ More stable cutting and longer tool life in stainless steel machining
This size range is especially suitable for:
• Pocket milling and bottom surface finishing
• Stainless steel components in medical, energy, and precision industries
• High-speed machining and dynamic toolpaths

Q1. What is a corner radius end mill used for?
Corner radius end mills are designed to improve tool strength at the corner area.
They are ideal for semi-finishing and finishing flat surfaces, shoulders, slots, and mild 3D contours with higher stability and longer tool life.
Q2. What types of stainless steel does it support?
•304 / 316 austenitic stainless
•410 / 420 martensitic stainless
•Duplex stainless steels
Q3. Do you support OEM customization?
Yes! We customize:
•Corner radius (e.g. R0.5 / R1 / R2…)
•Shank diameter
•Flute length & overall length
•Coating types and geometry
Support mold, medical and automation manufacturing.
Q4. Are standard sizes available in stock?
Yes, standard specifications are available for fast delivery with 1-3 days. Custom milling tools follow order schedule with 7-15 days.
Q5. Could we receive samples for performance testing?
For sample testing, please send us your tool list or application details. We will evaluate feasibility and provide a quotation or sample plan for your reference. If there are no problems, I will apply for free samples.
Q6. Can you provide 2 flute and 4 flute corner radius end mills?
Yes. Dohre CNC can provide both 2 flute and 4 flute options based on different machining requirements.
Q7. How do you handle quality control, and what is your procedure for handling complaints or claims?
We currently have three quality control processes. The tool profile is inspected using the German Helicheckplus testing equipment, and the appearance is inspected using a 2D 150x and 300x magnification microscope. Furthermore, our tool passivation uses a fluid blasting process, and the passivation value can be controlled within 3µm. The tool production also uses German Walter equipment, which effectively improves the precision and quality stability of the tools. Moreover, if there are any quality problems with our products, we will replace them free of charge.
