Seco 17014245 Roughing End Mill 1-1/4 in 6 Flute Cobalt

Product Description

The SECO 17014245 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers durability and heat resistance during heavy cuts. The 1.25-inch mill diameter, 6-flute spiral configuration, and 30-degree maximum helix angle work together to produce a shearing, chip-breaking action that reduces vibration and cutting forces. This tool is suited for machinists and toolroom professionals running conventional milling operations on steel, stainless, and other ferrous materials where rough stock removal is the priority.

This roughing end mill fits standard milling machines, CNC machining centers, and manual mills in job shop and production environments. The 0.75-inch shank diameter accommodates common end mill holders and collet chucks. With a 1.5-inch length of cut and 3.75-inch overall length, it is sized for moderate-depth passes in roughing cycles. The right-hand cutting and right-hand flute direction suit standard spindle setups. It is a single-end tool, meaning once the cutting end is worn, the tool is replaced rather than indexed.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• 6-flute spiral design for efficient chip evacuation and reduced chatter during roughing passes
• 30-degree maximum helix angle for smooth, shearing cut action
• Bright, uncoated finish — compatible with standard cutting fluids and coolant flood applications
• Right-hand cut and right-hand flute direction for standard milling setups
• Non-centercutting design — requires a pre-drilled or pre-bored entry point; not for plunge cutting

Compatibility

Designed as an OEM-style replacement or direct sourcing option for 0.75-inch shank end mill holders and ER-series collet chucks used in standard milling machine and CNC machining center setups requiring a 1.25-inch diameter roughing end mill.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 0.75-inch shank fully into the end mill holder or collet chuck and torque to the machine tool manufacturer's specification before engaging the spindle. This tool is non-centercutting — always begin cuts from a pre-drilled hole or at the workpiece edge. Confirm spindle direction is set to right-hand rotation before starting the cut.
