CBN Corner Radius End Mills
Finishing hardened-steel floors, profiles and fillet transitions.
A corner radius CBN cutter combines a flat-bottom form with a radiused outer corner. It is reviewed for floors and transition surfaces where the drawing allows that radius. Define the finished fillet and remaining stock before comparing it with a square or ball nose tool.

Application guide
Where cbn corner radius end mills fit.
Use the part feature and its acceptance requirements to narrow the tool choice.
Shoulder fillets
Match the cutter corner to the permitted component radius.
Profile finishing
Identify changes in engagement around corners and contours.
Selection & configuration
Define the details that change the tool.
Check the corner radius against the smallest fillet on the drawing and identify any interrupted edges that could shock the cutting tip.
| Decision | What to specify | Why it matters |
|---|---|---|
| Corner radius | Finished fillet and tool-radius requirement | A large tool radius may leave unwanted material. |
| Flat diameter | Cutter diameter and usable flat portion | The corner radius changes the bottom profile. |
| Stock variation | Allowance along the transition | Local excess stock changes edge loading. |

Build your configuration brief
Include these details so the tool dimensions and application can be reviewed together.
- Steel grade
- Actual hardness
- Cutter diameter
- Radius
- Finishing allowance
- Surface requirement
From drawing to inspection
Agree on what needs to be measured.
A tool specification should describe both the cutting geometry and the acceptance requirements. Mark critical dimensions on the drawing and discuss how they will be checked before ordering.
- Geometry reviewConfirm the profile, working length, access and critical dimensions.
- Inspection requirementsSpecify dimensional or profile checks and any reporting requirements.
- Application verificationAgree on sample evaluation where a new material, geometry or process needs a trial.
Selection questions
Before you order.
Practical answers for cbn corner radius end mills.
Does a corner radius tool produce the same surface as a ball nose?
No. It retains a flat-bottom region with a radiused corner, while a ball nose has a continuous rounded end. Match the form to the surface.
What should I include when requesting cbn corner radius end mills?
Steel grade; actual hardness; cutter diameter; radius; finishing allowance; surface requirement. Add the quantity and delivery destination. A drawing or marked part section helps identify critical dimensions and clearance constraints.
How are dimensions and delivery confirmed?
The quotation and agreed drawing define the tool configuration, inspection scope, quantity and delivery schedule. Reference images show the tool family; use the confirmed specification for ordering.
