เอ็นมิลล์บูลโนสคืออะไร?
A bull nose end mill is a milling cutter with a flat bottom and a corner radius. It combines the cutting ability of a square end mill with better corner strength. ดังนั้น, it is widely used in CNC machining where both dimensional stability and surface quality are important.
Bull nose end mills are also called corner radius end mills, ดอกเอ็นมิลล์รัศมี, or radiused end mills. These names usually refer to the same tool geometry: a flat-bottom end mill with a rounded corner radius.
This design gives the tool better corner strength than a sharp square end mill, while still keeping a flatter cutting bottom than a ball nose end mill. ดังนั้น, it is widely used for CNC milling, mold machining, การกัดรูปร่าง, กึ่งสำเร็จ, และการดำเนินการขั้นสุดท้าย.
Compared with a sharp-corner end mill, a bull nose end mill helps reduce corner chipping and improve tool life. ส่งผลให้, it is a practical choice for semi-finishing, ตกแต่ง, การกัดรูปร่าง, and mold-related applications.

ดอกเอ็นมิลล์บูลโนส, ดอกกัดเอ็นมิลรัศมีมุม, and Radius End Mill
A bull nose end mill, ดอกเอ็นมิลล์รัศมีมุม, and radius end mill usually describe the same type of CNC milling cutter. The tool has a flat cutting bottom and a rounded corner radius. This structure helps reduce corner chipping, improve edge strength, and create smoother transitions during machining.
Compared with a square end mill, a bull nose end mill offers better corner durability. Compared with a ball nose end mill, it keeps more flat-bottom cutting ability. ส่งผลให้, it is a practical choice for steel, สแตนเลส, alloy parts, โพรงแม่พิมพ์, and precision profiles.
Key Features of Our Bull Nose End Mill
Corner Radius for Better Edge Strength
The rounded corner strengthens the cutting edge and lowers the risk of chipping. Because of this, the tool performs more reliably in demanding machining conditions.
Solid Carbide for Stable CNC Performance
Our carbide bull nose end mill is designed for stable cutting, อายุการใช้งานยาวนาน, and consistent dimensional control. It is suitable for CNC machining centers that require repeatable performance.
High Precision Cutting Edge
A precise cutting edge helps improve surface finish and supports accurate contour milling. This is especially important for mold parts, พื้นผิวโค้ง, and detailed profiles.
ตัวเลือกการเคลือบหลายแบบ
Different coatings are available for different workpiece materials and cutting conditions. This helps improve wear resistance, ทนความร้อน, and overall productivity.
Custom Manufacturing Support
We support custom diameter, รัศมีมุม, การออกแบบขลุ่ย, การเคลือบ, and overall geometry based on your drawing or application requirements.
Bull Nose End Mill Sizes and Radius Options
We offer a wide range of bull nose end mill specifications for different machining tasks.
Common Size Range
- เส้นผ่านศูนย์กลาง: 1 mm to 20 มม
- ขลุ่ย: 2 ขลุ่ย / 4 ขลุ่ย
- รัศมีมุม: R0.5 to R5
- Hardness range: HRC45 / HRC55 / HRC60 / HRC65+
Smaller diameters are suitable for detailed contour work and fine features. Larger sizes are better for stronger cutting and improved rigidity.
How to Choose the Right Radius
A smaller corner radius is useful for finer profiles and tighter tool paths. ในทางตรงกันข้าม, a larger radius provides better edge strength and is often preferred for heavier cutting or longer tool life.

How to Choose a Bull Nose End Mill by Material
Choosing the right bull nose end mill depends on the workpiece material, cutting method, and finish requirement.
For Steel
For general steel machining, a carbide bull nose end mill with the right coating can deliver stable cutting performance and good wear resistance. It is suitable for contour milling, การกัดข้าง, and semi-finishing.
For Stainless Steel
Stainless steel requires good heat resistance and edge stability. ดังนั้น, a properly coated bull nose end mill with suitable flute geometry is often a better option for consistent cutting.
For Alloy and Hardened Materials
For high-hardness alloys or hardened steel, tool rigidity and coating performance become even more important. In these cases, the right corner radius can help reduce edge breakage and improve tool life.
โดยนับขลุ่ย
ก 2 flute design may be suitable for better chip evacuation in some conditions, while a 4 flute design is often preferred for stronger cutting and improved finish in harder materials.
Typical Applications of Bull Nose End Mill
A bull nose end mill is widely used in precision CNC machining because it offers a good balance between cutting efficiency and edge protection.
Contour Milling
It is suitable for contour milling where smooth transitions and stable cutting are required.
Semi-Finishing and Finishing
The corner radius helps reduce stress concentration, so the tool performs well in semi-finishing and finishing operations.
Mold and Die Machining
Bull nose end mills are commonly used in mold cavities, พื้นผิวโค้ง, and profile machining where both accuracy and surface finish are important.
General Precision Part Machining
They are also used for machining steel parts, stainless steel components, alloy workpieces, and other precision industrial parts.
