YG1 UGMF72903 | 0.3750" Diameter x 0.3750" Shank x 0.5000" LOC x 4.0000" OAL 4 Flute Y-Coated Carbide Corner Chamfer End Mill

Description

The YG1 UGMF72903 4 flute carbide end mill is a high-performance solid carbide cutting tool engineered for precision chamfering and fine feature milling across a variety of industrial machining applications where tight tolerances and smooth finishes are essential. This YG1 carbide corner chamfer end mill incorporates premium micro-grain carbide substrate with advanced Y-coating technology that improves wear resistance, heat tolerance, and edge strength for long tool life and consistent performance under demanding cutting conditions. With four precisely ground flutes, it offers balanced cutting action, efficient chip evacuation, and reduced vibration during high-speed and high-feed machining operations. The 0.3750" diameter and 0.3750" shank provide stability and rigidity, while the 0.5000" length of cut and 4.0000" overall length support deeper engagement and extended reach in precision machining tasks. Designed for corner chamfer work, this tool produces clean, accurate chamfers and edge blending with minimal burr formation and superior surface integrity. The carbide substrate delivers excellent hardness and toughness, making the tool suitable for a wide range of materials including steels, stainless steels, non-ferrous alloys, and engineered composites. As a YG1 UGMF72903 0.375" end mill, it balances rigidity and versatility for precision milling, profiling, and slotting operations. Its polished flutes and advanced coating reduce heat buildup and improve chip flow, extending cycle life and lowering the risk of premature wear. The tool’s corner chamfer profile supports consistent feature creation on workpieces requiring complex edge geometries or finish cleanup. Recognized among high performance carbide end mills, this cutter offers reliable repeatability and excellent finishing capability. It is commonly employed in mold and die work, aerospace component machining, and production environments calling for high quality, reproducible results. Careful setup and appropriate feed-rate selection further enhance cutting efficiency and surface quality during heavy-duty milling operations. This end mill is a reliable choice for precision chamfering and profile work in professional machine shop settings.
