Premium Solid Carbide Construction: Made from micrograin carbide, Pro Edge Technology end mills offer exceptional hardness, wear resistance, and heat tolerance. The rigid carbide core minimizes deflection during high-speed operations, extending tool life and maintaining edge integrity even in demanding materials like hardened steels and alloys Advanced TiAlN Coating for Enhanced Durability: The titanium aluminum nitride (TiAlN) coating provides superior heat resistance (up to 800℃) ,oxidation resistance and reduced friction, significantly improving tool lifespan. This coating also enhances chip evacuation, reducing built-up edge and ensuring smoother cuts across prolonged machining sessions Versatile Material Compatibility: Designed for machining a wide range of metals, including carbon steel, stainless steel, cast iron, aluminum, and copper alloys. Whether roughing, finishing, or side milling, these end mills excel in aerospace, automotive, and mold-making industries Optimized for CNC & Benchtop Machines: Compatible with CNC machining centers, engraving machines, and benchtop mills, these end mills feature an up-cut spiral design for efficient chip removal. Their balanced geometry reduces vibration, making them ideal for high-RPM operations on both industrial and hobbyist equipment Precision Sizing & High Accuracy: Crafted with exacting tolerances, these square end mills feature a cutting diameter of 1/4". The precision-ground cutting edges and optimized helix angle (35°–38°) deliver clean, sharp finishes on flat surfaces, slots, and edges, ideal for applications demanding tight dimensional control, the U-shaped groove design greatly enhances chip removal performance and improves cutting efficiency End Mill Set: Cutting diameter: 1/8" - 3/8"(1/8"x2, 3/16"x1, 1/4"x1, 5/16"x1, 3/8"x1). The precision-ground cutting edges and optimized helix angle (35°–40°) deliver clean, sharp finishes on flat surfaces, slots, and edges, ideal for applications demanding tight dimensional control
