Hertel 88245337 Roughing End Mill 1 in 5 Flute Cobalt Ticn

Product Description

The HERTEL 88245337 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 TiCN for improved wear resistance and heat dissipation, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The coarse pitch, 5-flute geometry breaks chips efficiently and reduces chatter during heavy cuts. With a 1-inch cutting diameter, a 2-inch length of cut, and a 4.5-inch overall length, this tool fits standard milling machine spindles and CNC machining center setups. Licensed machinists and toolroom professionals are the primary users.

This end mill is suited for roughing passes on steel, stainless steel, and similar alloys in both job-shop and production environments. The 1-inch shank diameter seats directly into ER or side-lock holders without a reduction collet. The regular-length body keeps deflection manageable in typical vertical milling and CNC knee-mill setups. Right-hand cut and right-hand flute direction are standard for conventional milling machine spindle rotation.

Key Features

• M42 cobalt steel construction for elevated red-hardness and tool life over standard M2 HSS
• TiCN coating reduces friction and extends cutting life in abrasive materials
• Coarse pitch, 5-flute design promotes efficient chip evacuation during heavy roughing passes
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• 1-inch shank diameter matches cutting diameter for direct collet or side-lock mounting
• Right-hand cut and right-hand helix for standard spindle rotation compatibility

Compatibility

Designed as a direct-fit roughing end mill for standard 1-inch tool holders, ER collet chucks, and side-lock holders used in vertical mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank to the recommended gauge depth in the holder and verify runout with a dial indicator before initiating a cut. Follow the tool manufacturer and machine manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.
