Round Nose End Mills

Taizhou OYT has made its mark in Taizhou's mechanical tooling sector. Specializing in tool manufacturing, the company takes particular pride in its round nose end mills. These precision tools combine premium materials with skilled craftsmanship to handle complex machining tasks like chamfers and fillets with excellent accuracy. Mold makers and aerospace manufacturers regularly choose OYT's tools for their consistent cutting quality and impressive durability. Through ongoing innovation and product refinement, OYT continues to deliver high-performance tools that meet the demanding needs of modern machining operations.

OYT Machining's products will not disappoint you. OYT's Round Nose End Mills are forged from ultra-fine tungsten steel (tungsten content ≥90%) and vacuum sintered to a hardness of HRC 78-82. Their flexural strength exceeds 3200 MPa. Their uniform microstructure ensures excellent fatigue resistance even at high speeds of 10,000-25,000 rpm. A nano-coating (2800-3500 HV) ensures stable chip control at cutting speeds of 80-180 m/min and feed rates of 0.1-0.3 mm/tooth. Furthermore, the reinforced cutting edge design, with its thickened support and negative chamfer, significantly improves impact resistance, effectively preventing chipping when roughing large molds (HRC 30-45 steel) and significantly increasing material removal rates. These tools are a must-have for your tooling needs.

Round Nose End Mills

OYT Round Nose End Mills feature an arc-edged geometry that optimizes cutting force distribution. Compared to flat-end mills, this design reduces radial forces by >30%, minimizing workpiece deformation risk—critical for mold cavities and aerospace thin walls.  

OYT Round Nose End Mills The continuous cutting edge maintains surface roughness (Ra) at 0.4–1.6μm, frequently eliminating secondary polishing on precision components.  

Forging from ultra-fine tungsten steel (≥90% WC) yields HRC 78-82 hardness and >3200MPa bending strength post vacuum sintering. The homogeneous microstructure provides superior fatigue resistance at 10,000–25,000rpm.  

OYT Round Nose End Mills Nano coatings (2800-3500 HV) ensure consistent chip control across 80–180m/min cutting speeds and 0.1–0.3mm/tooth feed rates. Suitable for full-process machining of steels, stainless, hardened materials (≤HRC 45), and high-temp alloys.
