CoroMill 316 Grade 1730 High Toughness Chamfer Milling Head with 45° Chamfer Geometry and EH16 Quick-Change Interface

316-16CM210-16045G 1730 is authentic Swedish S Coromant CoroMill 316 series modular replaceable solid carbide chamfer milling head, specially developed for universal 45° chamfering, edge deburring and light semi-finish profiling of steel, stainless steel, cast iron and superalloy workpieces. Equipped with standard Coromant EH16 quick-change interface, symmetrical 2-flute optimized chip flute and wide 1.5–16mm variable cutting diameter range, one single milling head covers multi-size hole edge chamfer and outer contour deburring tasks. Adopting grade 1730 anti-wear TiAlN PVD coated ultra-fine grain carbide substrate, it perfectly matches EH16 modular shanks, supports quick tool head replacement without full tool disassembly, adapts to smooth continuous finishing and mild interrupted cutting of uneven forged and cast blanks. Widely applied on vertical & horizontal CNC machining centers for automotive shaft chamfer, injection mold edge deburr, hydraulic valve port chamfer and general machinery multi-size hole mass finishing production

• Modular quick-change split design (carbide head + separate EH shank), only replace worn milling head instead of the whole tool, drastically reduces workshop long-term cutting tool procurement cost
• Standard Coromant EH16 precision locking interface, high concentricity after quick replacement, eliminates runout error causing uneven chamfer size and surface defects
• Exclusive CM 45° fixed chamfer geometry, uniform edge breaking effect for outer contours, through holes and blind holes, avoids secondary manual deburring processes
• Symmetrical double spiral flute structure, smooth large-volume chip evacuation channel quickly discharges fine metal chips, prevents chip accumulation scratching finished workpiece edges
• Grade 1730 nano TiAlN multi-layer PVD coating with strong substrate bonding force, outstanding high-temperature wear resistance and anti-adhesion performance, solves stainless steel chip sticking and edge burr problems
• HC ultra-fine grain solid carbide blank, integral forming without welding, high bending strength and micro edge toughness, resists edge micro chipping during mild interrupted deburring of scaled blanks
• Wide variable cutting diameter range DC1.5–DCX16, one milling head handles tiny micro hole chamfer and large outer part edge breaking, simplifies workshop tool inventory quantity
• Precision micro edge honing treatment on cutting edge, enhances impact resistance under light intermittent cutting, extends service life under long-cycle mass production
• Optimized maximum cutting depth 7.23mm, supports deep hole inner edge chamfering unreachable by standard short chamfer tools, improves mold and hydraulic part processing efficiency

• Mild carbon steel, medium carbon structural steel, alloy structural steel, 304/316 austenitic stainless steel, grey cast iron, ductile iron, low-hardness heat-resistant superalloys, pre-hardened mold steel

• 45° through/blind hole inner edge chamfering, outer contour edge deburring, hydraulic valve port rounding, mold sharp edge breaking, light semi-finish profiling
