Seco 17010407 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The SECO 17010407 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool handles tough ferrous and non-ferrous materials where heat resistance and edge retention matter. The 5-flute spiral design with a 30-degree maximum helix angle produces a chip-breaking cut pattern that reduces cutting forces and controls vibration during heavy roughing passes. The 1-inch mill diameter paired with a 3/4-inch shank diameter makes it compatible with standard R8, CAT, and ER collet toolholders common in job shop and production environments. Right-hand cutting and right-hand flute direction are standard for conventional milling setups.

This end mill is suited for roughing operations on machining centers, knee mills, and CNC vertical mills in job shop, toolroom, and production settings. The 1-1/2-inch length of cut accommodates moderate-depth slotting, peripheral milling, and step milling on steel, stainless, and high-temperature alloys. It is not center-cutting, so plunge entry is not recommended without a pre-drilled pilot hole or ramping entry strategy. Machinists and toolroom operators running roughing programs on general-purpose materials will find this tool fits directly into standard tooling setups without modification.

Key Features

• M42 cobalt HSS construction for improved heat resistance and edge toughness in ferrous materials
• 5-flute spiral geometry for high feed rates and efficient chip evacuation during roughing
• 30-degree maximum helix angle reduces cutting forces and dampens vibration
• Bright, uncoated finish suitable for regrinding and use without supplemental coatings
• Right-hand cut and right-hand flute direction for standard milling machine setups
• Series REM445 single-end configuration with 3/4-inch shank for broad toolholder compatibility

Compatibility

Designed as a direct-fit roughing end mill for standard 3/4-inch bore toolholders including R8 collets, ER collet chucks, and side-lock holders used on vertical milling machines and CNC machining centers. No specific OEM system compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Seat the 3/4-inch shank fully into the toolholder and verify runout with a dial indicator before cutting. This tool is not center-cutting and requires a ramping entry or pre-drilled pilot hole for plunge operations.
