Seco 17007604 Roughing End Mill 3/8 in 5 Flute Solid Carbide

Product Description

The SECO 17007604 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from solid carbide with an AlTiN coating, it delivers high heat resistance and extended tool life in ferrous and hard materials. The 3/8 inch diameter cutter features 5 spiral flutes with a fine pitch geometry and a maximum helix angle of 45 degrees, producing efficient chip evacuation and reduced chatter during roughing passes. The center-cutting design allows plunge entry. Installed and operated by machinists and toolroom technicians, this end mill suits high-speed roughing on CNC machining centers and manual mills.

The 17007604 is suited for roughing operations on steel, stainless steel, and similar hard materials where heat buildup and tool wear are primary concerns. The AlTiN coating adds a hard, thermally resistant surface layer that extends cutting life in dry or minimum-quantity lubrication conditions. With a 1 inch length of cut and 2.5 inch overall length, it fits standard short-reach milling setups common in production and maintenance machining environments. Coolant-through capability is not included in this configuration.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides high-temperature resistance and extended tool life
• 5-flute fine pitch design promotes efficient chip evacuation and smooth cutting action
• 45-degree maximum helix angle reduces cutting forces and vibration
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Straight cylindrical shank with tight tolerance (-0.0001 to -0.0004 inches) for secure toolholder fit

Compatibility

Designed as an OEM-style solid carbide roughing end mill in the SR545 series, compatible with standard 3/8 inch collet chucks, end mill holders, and shrink-fit toolholders used on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning cuts. Do not exceed the rated helix angle or depth-of-cut parameters for the workpiece material.
