Hertel 750273 Square End Mill 1/4 in 4 Flute Carbide Tin

Product Description

The HERTEL 750273 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 1/4 inch diameter and a 1-1/8 inch length of cut, it handles slotting, profiling, and peripheral milling in a single-end configuration. The micrograin carbide substrate provides rigidity and edge retention, while the Titanium Nitride (TiN) coating reduces friction and extends tool life. A 30-degree helix angle and four right-hand spiral flutes support efficient chip evacuation. Overall length is 3 inches with a 1/4 inch shank diameter. This tool is installed by machinists and CNC operators working in job shops, tool rooms, and production machining cells.

This end mill is suited for milling ferrous and non-ferrous metals in both manual and CNC milling machines. Its centercutting geometry allows plunge entry as well as conventional milling passes. The 1/4 inch shank is compatible with standard collet chucks, end mill holders, and shrink-fit tooling systems commonly found in vertical machining centers and knee mills. It is a single-end tool, meaning the working end is on one side only.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiN coating reduces friction and extends tool life in ferrous applications
• 4 right-hand spiral flutes with 30-degree helix angle for effective chip removal
• Centercutting design supports both plunge and peripheral milling
• Right-hand cutting direction compatible with standard spindle rotation
• Single-end configuration with 1/4 inch straight shank

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems used in CNC vertical machining centers and conventional knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the toolholder to the recommended gauge depth before tightening. Ensure the spindle is fully stopped and the machine control is in a safe state before changing tooling. Follow the machine manufacturer and toolholder manufacturer torque specifications for collet nut or set screw engagement.
