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 مطحنة نهاية نصف قطرها الزاوية.

General Dimensions

Use the following dimensions to specify the tool:

Check these dimensions together when selecting a standard tool or confirming a non-standard design.

للأدوات غير القياسية, 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–Ø20 mm, with corner radii from R0.2 to R4 across the series. لوك, قطر عرقوب, and OAL vary by cutter diameter and tool design.

لكن, not every diameter is available with every radius or length combination. OMIST confirms flute finish, المعالجة السطحية, and cutting geometry according to the actual machining requirement.

4-Flute Standard Series

The confirmed 4-flute series covers cutter diameters of approximately Ø1–Ø20 mm.

Corner radii represented across the series include:

ص0.2 / 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.

Other D, R, لوك, عرقوب, and OAL combinations depend on the required tool geometry and machining application.

الخيارات القياسية والمخصصة

OMIST offers standard 3F and 4F مسلسل.

For applications outside the standard range, we can manufacture non-standard sizes and geometries. 2F, 5F, 6F, extended-length tools, and other flute configurations are available for custom requirements.

Custom options may include diameter, نصف قطر الزاوية, لوك, أول, حجم عرقوب, عدد الناي, helix, coating or surface treatment, هندسة القطع, center-cutting design, ومتطلبات التسامح.

فضلاً عن ذلك, selected 150 mm OAL configurations are available according to cutter diameter, يصل, والهندسة.

We confirm final manufacturability after reviewing the required dimensions and application.

التطبيقات والاختيار

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. للصلب, ستانلس ستيل, الصلب العفن, or hardened-steel applications, OMIST reviews material hardness, أبعاد الأداة, عملية التصنيع, يصل, 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.

وتشمل التطبيقات النموذجية:

• Contour milling
• طحن الملف الشخصي
• نصف تشطيب
• الانتهاء
• تصنيع القوالب والقالب
• Cavity machining
• Pocket machining where a corner radius is acceptable

Corner rounding form cutters are a different tool type used to produce an external workpiece radius. See نصف قطر الزاوية مقابل مطحنة نهاية التقريب الزاوية.

الميزات الرئيسية

• Flat Bottom with Corner Radius: Combines a flat cutting end with a defined corner radius.
• Standard 3F and 4F Series: Covers multiple metric diameter, نصف القطر, and length combinations.
• Application-Matched Configuration: Tool geometry and surface treatment depend on the workpiece and machining conditions.
• تصنيع مخصص: أبعاد غير قياسية, flute configurations, 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, الموزعين, and OEM requirements.

للأدوات غير القياسية, we review the required dimensions, هندسة, 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, رسم, عينة, or reference image for manufacturability review.

For quotation, please provide the main tool dimensions, مادة الشغل, عملية التصنيع, والكمية. 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.

الأسئلة المتداولة

هي مطحنة نهاية أنف الثور مثل مطحنة نهاية نصف قطر الزاوية?

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, 5F, 6F, and other flute configurations for custom requirements.

What standard sizes and corner radii are available?

The 3-flute aluminum series covers approximately Ø1–Ø20 mm, مع R0.2–R4 across the series.

The confirmed 4-flute range also covers approximately Ø1–Ø20 mm, مع ص0.2, R0.3, R0.5, R1, and R2 represented across the series.

Actual diameter, نصف القطر, and length combinations vary by tool size and design.

Can custom bull nose end mills be manufactured from a drawing?

نعم. OMIST can review non-standard dimensions and geometry from a drawing, الأبعاد المطلوبة, عينة, or machining information.

How should I request a quotation?

Send the main tool dimensions, مادة الشغل, عملية التصنيع, والكمية. For a non-standard tool, include a drawing or reference image when available.
