Precision Engineered for High-Performance Steel Machining

Our 3.7mm 4-flute carbide flat end mill is manufactured from ultra-fine grain tungsten carbide with optional TiCN or AlTiN coatings for exceptional durability in demanding CNC operations. The optimized 4-flute design balances material removal rate and surface finish quality, ideal for mold making, die manufacturing, and precision machining of steels up to HRC 55.

Key Features

Superior Tool Geometry: True 4-flute design with 30° helix angle, precision ground cutting edges (±0.005mm), and flat bottom design with <0.1mm corner radius
Advanced Material Technology: Sub-micron carbide substrate (0.5μm grain size) with TiCN or AlTiN coating options and polished flutes
Performance Advantages: 3-5× longer tool life vs HSS, 20% higher feed rates, superior surface finish (Ra 0.8μm), and reduced power consumption
Customization Options: Special diameters (3.5-4.0mm), various cutting lengths, multiple shank configurations, and special geometries

Applications

Mold & Die Industry: Precision cavities in P20, H13 mold steels, EDM electrode machining
Automotive Components: Transmission gear machining, engine block detailing
General Metalworking: Carbon steel fixture manufacturing, alloy steel prototype machining
Tool & Die Maintenance: Die repair and refurbishment, precision slot cutting
