Seco 17013502 Roughing End Mill 7/8 in 5 Flute Cobalt

Product Description

The SECO 17013502 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with titanium carbonitride (TiCN), this tool handles tough ferrous and non-ferrous materials while resisting heat and wear. The 5-flute, right-hand spiral configuration with a 30-degree maximum helix angle drives efficient chip evacuation during heavy roughing passes. With a 7/8 inch mill diameter and 3.5 inch length of cut, it covers substantial axial depths in a single setup. Machinists and tool-and-die professionals install this end mill in manual and CNC vertical mills as a primary roughing tool before finish passes.

The 17013502 suits roughing operations on steel, stainless, and alloy materials in job shop and production environments. The long flute configuration supports deep-pocket and side-milling applications where shorter tools cannot reach. The 7/8 inch straight shank fits standard ER collet chucks, end mill holders, and Weldon-style side-lock holders commonly used in both manual knee mills and CNC machining centers. This is a single-end tool, so once the cutting end is worn, the tool is replaced rather than flipped.

Key Features

• M42 cobalt construction resists heat buildup during aggressive roughing cuts
• TiCN coating extends tool life on ferrous and abrasion-prone workpiece materials
• 5-flute right-hand spiral geometry promotes efficient chip evacuation
• 30-degree maximum helix angle balances cutting force and surface finish
• Long-length series (REM710) with 3.5 inch length of cut for deep-reach applications
• Right-hand cutting direction compatible with standard spindle rotation on most mills

Compatibility

Designed as an OEM-style roughing end mill for use in standard 7/8 inch end mill holders, ER collet chucks, and side-lock holders on manual and CNC milling machines.

Installation Notes

A qualified machinist should install and set tool length offset before cutting. Power down and lock out the spindle before changing tooling. Ensure the holder and collet are clean and free of chips before seating the shank, and torque the retention hardware to the holder manufacturer's specification. Do not use this tool for plunge cutting, as this is a non-centercutting end mill.
