Seco 17010405 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The SECO 17010405 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it handles tough ferrous materials and demanding cutting conditions where standard HSS tooling falls short. The 1-inch diameter cutter carries five spiral flutes with a 30-degree maximum helix angle, delivering efficient chip evacuation and reduced cutting forces. With a 6-inch length of cut and an 8.5-inch overall length, this tool is suited for deep-pocket work and extended-reach applications. It ships bright and uncoated, ready for use in conventional or CNC milling setups. Licensed machinists and toolroom operators are the primary users.

This end mill is intended for use in horizontal and vertical milling machines, machining centers, and CNC knee mills where roughing passes are required on steel, cast iron, and similar ferrous workpieces. The right-hand cut and right-hand flute configuration matches standard spindle rotation on most production machines. The regular-length classification makes it a common choice for general shop roughing work before finishing passes are applied. No coolant-through capability means it relies on flood coolant or air blast directed externally at the cutting zone.

Key Features

• M42 cobalt steel construction for heat and wear resistance in demanding cuts
• Five spiral flutes with 30-degree helix angle for efficient chip evacuation
• 1-inch mill diameter with right-hand cut and right-hand flute direction
• 6-inch length of cut for deep-pocket and extended-reach milling
• Bright uncoated finish for compatibility with a wide range of cutting fluids
• Single-end design from the SECO REM445 series

Compatibility

Designed as an OEM-style roughing end mill for use in standard ER or end mill holders accepting a 1-inch straight shank on vertical or horizontal milling machines and CNC machining centers.

Installation Notes

Installation requires a properly sized end mill holder or collet chuck rated for a 1-inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Verify runout with a dial indicator after securing in the holder, as excessive runout accelerates wear on roughing geometry. Follow shop-standard feeds and speeds for M42 cobalt tooling in the workpiece material being cut.
