Precision Milling Cutters,Cutting Tools for CNC Machining Every Material
Product Overview
The Corner Rounding End Mill is a specialized cutting tool designed for machining precise radial edges on metal workpieces. With its unique flute geometry, it efficiently creates smooth radius transitions, eliminates sharp edges, and enhances part durability and safety. Furthermore, it is ideal for high-quality CNC machining, mold manufacturing, aerospace components, and other precision industrial applications.
Key Features of Our Corner Rounding End Mill
Premium Carbide Material & Coating
Crafted from submicron grain carbide and PVD-coated with TiAlN or AlCrN, this tool offers exceptional wear resistance and thermal stability, significantly extending its service life.Optimized Chip Evacuation Design
Featuring multi-flute options (2-4 flutes) and advanced helix and chip pocket designs, it enables smooth cutting and efficient chip removal, reducing clogging and re-cutting.High Precision & Consistency
The cutting edges are precision-ground to ensure accurate radius profiles and superior surface finishes, meeting stringent requirements in aerospace, automotive, and medical industries.Rigid Geometric Tool Design
Specially engineered cutting edge geometry balances shear efficiency and tool rigidity, minimizing vibration during operation and improving machining stability and part quality.Stringent Quality Assurance
Each tool undergoes dynamic balancing testing to ensure reliable high-speed performance, low vibration, and consistent results across diverse applications.

Industry Applications
Mold & Die Making: Precision radius machining and edge finishing for injection molds, die-cast molds, and stamping dies.
Automotive Manufacturing: High-accuracy edge radiusing for engine, transmission, and chassis components.
Aerospace Engineering: Machining high-strength alloy parts with strict tolerances and surface quality requirements.
Medical Device Production: Contour machining for surgical tools, implants, and diagnostic equipment.
General Precision Engineering: Deburring and edge processing for electronics, energy equipment, and industrial machinery.
How to Select the Right Corner Rounding End Mill
Match Coating to Material: Choose TiAlN for carbon steel, AlCrN for stainless steel or high-temperature alloys, and uncoated tools for non-ferrous materials like aluminum.
Select Size Based on Radius: Smaller radii require shorter flute tools; larger radii work best with multi-flute extended-reach designs.
Choose Flute Count per Operation: Use 2-flute end mills for roughing and deep slots; opt for 4-flute tools for finishing and light milling.
Consider Machine Tool Compatibility: Smaller machines work best with compact diameters; high-power CNC centers support larger tools. Use hydraulic or heat-shrink holders for high-speed applications and collet chucks for general use.
Request Customization When Needed: Custom flute angles, shank dimensions, and coatings are available for specialized uses in medical, 3C, and other industries.
