Seco 17003469 Square End Mill 3/4 in 5 Flute Solid Carbide

Product Description

The SECO 17003469 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. This single-end tool features a 3/4 inch cutting diameter, a 3-1/4 inch length of cut, and a 6 inch overall length with a matching 3/4 inch shank diameter. The 5-flute geometry paired with a 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin carbide and left uncoated in a bright finish, this end mill delivers consistent dimensional accuracy with a mill diameter tolerance of +0.0000 to -0.0020 inches. It belongs to the SECO S545 series and is center-cutting capable, allowing plunge entry into workpieces.

This end mill is suited for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining centers and manual knee mills. It is a single-end tool intended for production and job-shop environments where extended reach is not required and coolant is applied externally. Machinists and CNC operators working across ISO material groups P, M, K, S, N, and H will find this tool applicable to a broad range of roughing and finishing passes.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in ferrous and non-ferrous cutting
• 5-flute design with 45-degree helix angle for improved chip flow and surface finish
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Bright/uncoated finish suitable for aluminum and non-ferrous materials as well as general-purpose steel work
• Right-hand cut, right-hand flute configuration compatible with standard spindle rotation
• Series S545 with 3/4 inch shank for secure tool holding in standard ER, Weldon, and shrink-fit holders

Compatibility

Designed as an OEM-style solid carbide end mill for use in CNC machining centers, manual mills, and similar machine tool setups requiring a 3/4 inch straight shank with right-hand cut geometry.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet, Weldon side-lock, or shrink-fit holder rated for the 3/4 inch shank diameter and confirm runout is within acceptable limits before cutting. Do not exceed the manufacturer-recommended speeds and feeds for the workpiece material and depth of cut being used.
