Hertel 91196949 Roughing End Mill 2 in 8 Flute Cobalt

Product Description

The HERTEL 91196949 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers extended tool life and heat resistance under heavy cutting loads. The 2-inch diameter cutter features 8 fine-pitch flutes arranged in a right-hand cutting, right-hand flute configuration. It is not center-cutting, which makes it suited for peripheral and side milling rather than plunge operations. Machinists and toolroom professionals use this tool on mills and machining centers where stock removal rates and tool durability are the priority.

This roughing end mill is appropriate for use in both production shop and job-shop environments where ferrous and high-temperature alloy materials require rapid stock removal. The TiN coating reduces friction and improves chip evacuation, supporting longer run times between tool changes. With a 1-1/4-inch shank diameter and a 2-inch length of cut, it fits standard toolholders commonly found in vertical and horizontal milling setups. No extended reach and no variable helix keep the geometry predictable and rigid.

Key Features

• M42 cobalt HSS construction for high heat and wear resistance
• Titanium Nitride (TiN) coating reduces friction and extends tool life
• 8 fine-pitch flutes for efficient chip load and smooth cutting action
• Right-hand cutting and right-hand flute direction for standard milling spindles
• Single-end design with 2-inch length of cut maximizes rigidity
• Not center-cutting — optimized for peripheral and side milling passes

Compatibility

Designed for use in standard milling toolholders accepting a 1-1/4-inch shank diameter. Suited for vertical and horizontal milling machines used in production and toolroom applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and locked out before mounting or removing the end mill. Use a properly sized collet or end mill holder rated for the 1-1/4-inch shank to prevent runout and tool pullout under load. Confirm that the machine spindle direction matches the right-hand cutting requirement of this tool before starting a cut.
