Hertel E7050048 Square End Mill 3/4 in 2 Flute Cobalt

Product Description

The HERTEL E7050048 is a double-end cobalt square end mill designed for milling steel, stainless, and high-temperature alloys in demanding shop environments. Built from M42 cobalt high-speed steel, it carries a TiCN (titanium carbonitride) coating that extends tool life by reducing friction and heat buildup at the cutting edge. The 3/4 inch cutting diameter pairs with a 1-5/16 inch length of cut and a 5 inch overall length, giving machinists adequate reach for typical slotting, profiling, and peripheral milling operations. Two flutes with a 30-degree right-hand spiral helix provide efficient chip evacuation and a clean finish on most ferrous and non-ferrous workpieces. Installed by machinists and tool-and-die professionals on CNC machining centers and manual knee mills.

This end mill suits production and job-shop applications where a reliable, double-end cobalt tool reduces per-part cost. The centercutting geometry allows plunge entry directly into the workpiece without pre-drilling, supporting both slotting and ramping toolpaths. The 3/4 inch shank diameter fits standard R8, CAT, BT, and straight-bore collet toolholders common across vertical and horizontal machining centers. Right-hand cut and right-hand flute configuration is the industry-standard orientation for conventional and climb milling on CNC and manual equipment.

Key Features

• M42 cobalt HSS construction resists heat and wear in difficult-to-machine alloys
• TiCN coating reduces friction and extends cutting edge life versus uncoated tools
• Double-end design provides two usable cutting ends, lowering cost-per-edge
• Centercutting geometry allows direct plunge entry without pre-drilling
• 30-degree right-hand spiral flute promotes efficient chip evacuation
• Two-flute configuration suited for slotting and profiling in tougher materials

Compatibility

Designed as a standard-shank replacement end mill for use in 3/4 inch collet chucks, end mill holders, and milling adapters on CNC machining centers and manual knee mills requiring a 3/4 inch diameter square end geometry.

Installation Notes

Installation is performed by a machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each use, and confirm correct spindle rotation direction matches the right-hand cut geometry of this tool before starting the operation.
