Product Overview: Tungsten Carbide Corner Radius End Mill – RTB Series
【Product Features & Why We Recommend It】
- Large Helix Angle Design: Features a 45° large helix angle for a noticeably lighter and sharper cutting feel. Recommended for machining high-toughness or adhesion-prone materials, as it significantly reduces cutting heat and promotes smoother chip evacuation.
- Anti-Chipping Protection: The ball nose (R-nose) design reinforces cutting edge strength, recommended for flat surface machining or curved surface semi-rough milling — reducing corner chipping caused by uneven load distribution and delivering better stability than standard square-end mills.
- Optimized for Difficult-to-Machine Materials: Manufactured with SMG0.6 tungsten carbide substrate and G10 coating, with hardness compatibility up to HRC55, offering toughness characteristics well-suited to variable machining environments.
- Enhanced Tool Longevity: The coating slows the rate of tool wear, making it a recommended choice for improving throughput — especially when machining materials prone to work hardening.
【Machining Applications】
- Primary Use: Stainless steel component machining, difficult-to-machine material curved surface milling, and flat surface anti-chipping cutting.
- Recommended Work Materials:
- M-Class (Stainless Steel): Materials such as SUS304 and SUS316 with high toughness and difficult chip breakage characteristics.
- S-Class (Superalloys / Titanium Alloys): Provides relatively stable cutting tool life for Ti-6Al-4V, pure titanium, and nickel-based superalloys with their characteristically hard and adhesive nature.
