面向经销商和加工买家的圆鼻立铣刀与平底立铣刀对比指南。
A corner radius end mill and a square end mill can look similar in a catalog, but they solve different problems. The square tool creates a sharp internal corner, while the corner radius tool adds edge strength for heavier loads and longer life.
Compare the two product families
Corner Radius End Mills
Bull nose and corner radius carbide end mills for stronger edges and side milling.
Square End Mills
Square carbide end mills for slots, shoulders, flat bottoms and sharp corners.
OEM Carbide End Mills
Build a private-label end mill range with both square and corner radius geometry.
Quick comparison
| Geometry | Choose it when | Tradeoff |
|---|---|---|
| Square end mill | The part requires a sharp shoulder, slot corner or flat-bottom feature. | The sharp corner is more vulnerable under heavy load. |
| Corner radius end mill | Tool life, edge strength and profiling stability matter more than a sharp corner. | The part will have a small radius at the internal corner. |
| Ball nose end mill | The feature is curved, contoured or 3D finished. | Not intended for sharp shoulders or flat-bottom pockets. |
Catalog advice for distributors
- Carry square end mills as the general-purpose base range.
- Add corner radius tools for steel, stainless steel and higher-load machining.
- Define radius options clearly because buyers search by diameter and R value.
- Use separate landing pages and internal links so Google understands the geometry difference.
Send your target end mill catalog. We can help structure square and corner radius carbide end mills for distributor sourcing.
