Ultra-Shear 4-Flute Solid Carbide End Mills
Engineered for Precision. Built for Performance.
Whether you're machining tool steel, mild steel, or alloy steel, the Ultra-Shear 4-Flute Solid Carbide End Mills deliver consistent, high-quality results cut after cut. Designed for general-purpose steel cutting, these end mills feature an optimized geometry that balances efficient material removal with superior surface finishes—saving you time in both machining and post-processing.
Key Features That Maximize Performance
🔹 4-Flute Design
Optimized to deliver fast stock removal while maintaining a clean, smooth finish on floors and walls—perfect for profile milling, slotting, and contouring in steel.
🔹 30° Helix Angle
Strikes the ideal balance between cutting force and finish quality, improving tool life while reducing vibration and chatter during operation.
🔹 Center-Cutting Geometry
Allows for precise plunging, ramping, and helical entry, increasing versatility in your milling strategies.
🔹 Uncoated Solid Carbide
Perfect for general-purpose steel machining—ideal when coolant is used or coating isn't needed. Made from high-grade American solid carbide for long tool life and consistent results.
🔹 Precision Ground Tolerances
- Shank Tolerance: H6
- Diameter Tolerance: +.0000" / –.0005"
These tight tolerances ensure repeatable, reliable performance in CNC, manual, and semi-automatic setups.
Available Sizes
- 1/8" Diameter
• Cut Length: 3/8" or 1/2" - 1/4" Diameter
• Cut Length: 3/4"
All with standard 4-flute geometry and center-cutting capability.
