Uncoated Solid Carbide Inner R End Mills

Unmatched Technical Advantages

✅ Full Solid Carbide Construction
Ultra-fine micrograin tungsten carbide (German powder metallurgy) delivers exceptional hardness (HRA≥93) and fracture resistance (TRS≥4200MPa) – unleashing raw material potential.

✅ Bare Substrate Excellence
• Nano-honed cutting edges ensure ultra-sharpness for burr-free finishing
• Zero coating delamination risk in non-ferrous alloys (Al/Cu/Mg) & hardened steels (HRC50+)
• Ideal for medical-grade surface finishes (Ra≤0.2μm)

✅ Anti-Vibration Geometry
• High rigidity core + reduced neck length combat chatter in deep cavities
• 45° high helix enhances chip flow in internal contours
• Radial runout ≤3μm guarantees ±0.01mm profile accuracy

Industry-Specific Solutions

⮞ Aerospace: Blade root fillets & engine casings
⮞ Automotive: Transmission housing radii & die undercuts
⮞ Medical: Implant concave surfaces & surgical tool cavities
⮞ Electronics: 5G heatsink channels & aluminum enclosure radii

Cutting-Edge Capabilities

▷ High-speed machining (HSM): Up to 30,000 RPM
▷ Hard milling: Compatible with HRC65 materials
▷ Radius range: R0.1-R15mm (customizable)
▷ Coolant options: Through-tool coolant/Ejector system

Engineering Bulletin: These uncoated Inner R tools outperform coated alternatives in titanium alloys and glass-filled polymers with 40% longer tool life due to superior heat dissipation.
