Bull Nose End Mill Specification Options
A bull nose end mill has a flat cutting bottom with a defined corner radius at the outside cutting edge. Tooling catalogs also commonly list this geometry as a 코너 반경 엔드밀.
General Dimensions
Use the following dimensions to specify the tool:
| Symbol | 차원 |
|---|---|
| 디 | 커터 직경 |
| 아르 자형 | 코너 반경 |
| LOC | 절단 길이 |
| 디 | 생크 직경 |
| 오알 | 전체 길이 |
| Z | 플루트 수 |
Check these dimensions together when selecting a standard tool or confirming a non-standard design.
비표준 도구용, send a drawing when available.
3-Flute Aluminum Series
OMIST offers a standard 3-flute series for aluminum and aluminum-alloy machining.
The confirmed series covers cutter diameters of approximately Ø1~Ø20mm, with corner radii from R0.2 to R4 across the series. LOC, 생크 직경, and OAL vary by cutter diameter and tool design.
하지만, not every diameter is available with every radius or length combination. OMIST confirms flute finish, surface treatment, and cutting geometry according to the actual machining requirement.
4-Flute Standard Series
The confirmed 4-flute series covers cutter diameters of approximately Ø1~Ø20mm.
Corner radii represented across the series include:
R0.2 / R0.3 / R0.5 / R1 / R2
Not every radius is available with every cutter diameter. The table below shows representative confirmed configurations rather than a complete model list.
| 디 (mm) | 아르 자형 (mm) | LOC (mm) | Shank d (mm) | 오알 (mm) | 플루트 |
|---|---|---|---|---|---|
| 1 | 0.2 | 3 | 4 | 50 | 4에프 |
| 4 | 0.5 | 10 | 4 | 50 | 4에프 |
| 6 | 1 | 18 | 6 | 75 | 4에프 |
| 8 | 1 | 24 | 8 | 75 | 4에프 |
| 10 | 1 | 30 | 10 | 100 | 4에프 |
| 12 | 1 | 36 | 12 | 100 | 4에프 |
| 14 | 2 | 35 | 14 | 100 | 4에프 |
| 16 | 1 | 40 | 16 | 100 | 4에프 |
| 20 | 1 | 40 | 20 | 100 | 4에프 |
Other D, 아르 자형, LOC, 정강이, and OAL combinations depend on the required tool geometry and machining application.
표준 및 사용자 정의 옵션
OMIST offers standard 3F and 4F 시리즈.
For applications outside the standard range, we can manufacture non-standard sizes and geometries. 2에프, 5에프, 6에프, extended-length tools, and other flute configurations are available for custom requirements.
Custom options may include diameter, 코너 반경, LOC, 오알, 생크 크기, 플루트 수, helix, 코팅 또는 표면 처리, 절단 형상, 센터 커팅 디자인, 공차 요구 사항.
게다가, 선택된 150 mm OAL configurations are available according to cutter diameter, 도달하다, 기하학과.
We confirm final manufacturability after reviewing the required dimensions and application.
응용 및 선택
The 3-flute standard series is mainly intended for aluminum and aluminum-alloy machining.
The 4-flute series provides the main standard range for other machining requirements. 철강용, 스테인레스 스틸, 금형강, or hardened-steel applications, OMIST reviews material hardness, 도구 치수, 가공 작업, 도달하다, and cutting conditions before confirming the final configuration.
We also select coating or surface treatment according to the actual application rather than using one fixed specification for the whole product family.
일반적인 응용 분야는 다음과 같습니다.:
- 윤곽 밀링
- 프로파일 밀링
- 준마무리
- 마무리 손질
- 금형 및 다이 가공
- 캐비티 가공
- Pocket machining where a corner radius is acceptable
For applications that require a sharp cutting corner, 보다 불 노즈 vs 플랫 엔드밀.
평면 바닥 반경 커터와 완전히 둥근 절삭 엔드 사이의 차이점, 보다 Bull Nose vs Ball Nose End Mill.
Corner rounding form cutters are a different tool type used to produce an external workpiece radius. 보다 코너 반경과 코너 라운딩 엔드 밀.
주요 특징
- Flat Bottom with Corner Radius: Combines a flat cutting end with a defined corner radius.
- Standard 3F and 4F Series: Covers multiple metric diameter, 반지름, and length combinations.
- Application-Matched Configuration: Tool geometry and surface treatment depend on the workpiece and machining conditions.
- 맞춤형 제조: 비표준 치수, 플루트 구성, and cutting geometry can be produced from customer requirements or drawings.
Custom Bull Nose End Mill Manufacturing
OMIST supports standard and custom solid carbide bull nose end mills for machining companies, 유통업체, 및 OEM 요구 사항.
비표준 도구용, we review the required dimensions, 기하학, center-cutting requirement, and dimensional or radius tolerance against the drawing and machining application.
If a standard size does not fit the part, send the required dimensions, 그림, 견본, or reference image for manufacturability review.
For quotation, please provide the main tool dimensions, 공작물 재료, 가공 작업, 수량. A drawing is preferred for non-standard requirements, but we can also make an initial review from the available dimensions and machining information.
We confirm MOQ, achievable tolerance, and lead time after reviewing the specification and quantity.
FAQ
불 노즈 엔드밀은 코너 반경 엔드밀과 동일합니까??
For the flat-bottom, radiused-corner geometry covered on this page, “bull nose end mill” is a common market name, while tooling catalogs often use “corner radius end mill.” Confirm the exact tool by its dimensions and geometry.
What flute counts are available?
The standard ranges include a 3-flute aluminum series and a 4-flute series. OMIST can also produce 2F, 5에프, 6에프, and other flute configurations for custom requirements.
What standard sizes and corner radii are available?
The 3-flute aluminum series covers approximately Ø1~Ø20mm, ~와 함께 R0.2–R4 across the series.
The confirmed 4-flute range also covers approximately Ø1~Ø20mm, ~와 함께 R0.2, R0.3, R0.5, R1, and R2 represented across the series.
Actual diameter, 반지름, and length combinations vary by tool size and design.
Can custom bull nose end mills be manufactured from a drawing?
예. OMIST can review non-standard dimensions and geometry from a drawing, 필수 치수, 견본, or machining information.
How should I request a quotation?
Send the main tool dimensions, 공작물 재료, 가공 작업, 수량. For a non-standard tool, include a drawing or reference image when available.
