Seco 17003625 Solid Carbide Square End Mill 1in 5 Flute

Product Description

The SECO 17003625 is a solid carbide square end mill designed for high-performance milling in demanding metalworking applications. Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it delivers excellent wear resistance and heat tolerance at elevated cutting speeds. The tool features a 1 inch mill diameter, a 2 inch length of cut, and a 4 inch overall length. The 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of ferrous and non-ferrous workpiece materials. This is a single-end tool with a straight 1 inch shank.

The 17003625 is suited for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. The Series S545 designation places it in a short-length geometry category, making it appropriate for rigid setups where minimizing deflection is critical. It is a right-hand cut, right-hand flute tool with spiral fluting and is centercutting, allowing plunge entry. Machinists and tool-and-die professionals will find it well-matched to CNC vertical and horizontal machining center operations where close tolerances and surface finish quality are required.

Key Features

• AlTiN coating provides high hardness and oxidation resistance for extended tool life in ferrous materials
• Micrograin carbide substrate supports sharp edges and fine surface finishes
• 45-degree helix angle promotes efficient chip flow and reduces chatter
• Centercutting geometry allows direct plunge milling without pre-drilled entry
• Right-hand cut and right-hand flute configuration for standard CNC spindle use
• Tight tolerances: mill diameter -0.0000/-0.0020 inches, shank diameter -0.0001/-0.0004 inches, OAL plus or minus 0.0015 inches

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers accepting a 1 inch straight shank; compatible with standard ER or end mill holder tooling systems accommodating that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle and tool holder are clean and free of chips before seating the shank. Torque the end mill holder or collet nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator prior to cutting; maximum TIR for this tool is 0.0005 inches.
