Seco 17003612 Square End Mill 0.5in 5 Flute Carbide S545

Product Description

The SECO 17003612 is a single-end square end mill designed for high-performance material removal in demanding machining applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness retention and heat resistance during aggressive cuts. The 5-flute geometry with a 45-degree right-hand helix provides efficient chip evacuation and a smooth surface finish. At 0.5 inches in diameter with a 1.25-inch length of cut and 3-inch overall length, it fits standard toolholding setups used in milling centers across production and job shop environments. This tool is center-cutting and runs in a right-hand cutting direction with a straight shank.

This end mill is engineered for machining steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. It fits the ISO material group classifications P, M, K, S, N, and H, making it a versatile choice for shops running mixed workpiece materials on CNC vertical or horizontal machining centers. The Series S545 designation targets applications where tool life and edge stability under high-speed or high-feed conditions are a priority. It is suited for slotting, profiling, and peripheral milling passes where a 5-flute carbide tool is specified.

Key Features

• Micrograin solid carbide substrate for rigidity and edge retention
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• 5 right-hand spiral flutes with 45-degree helix for efficient chip flow and reduced chatter
• Center-cutting design allows plunge entry without a pilot hole
• Straight 0.5-inch shank fits standard ER and hydraulic toolholders
• Mill diameter tolerance of -0.0000 / -0.0020 inches ensures consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC milling applications requiring a 0.5-inch diameter, 5-flute solid carbide square end mill with a straight shank in the SECO Series S545 family.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and the tool carousel is in a safe state before changing tooling. Verify toolholder runout does not exceed the 0.0005-inch maximum TIR specification before committing to production cuts. Confirm proper torque on collet nuts or set screws per the toolholder manufacturer's guidelines.
