Hertel 750371 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The HERTEL 750371 is a solid carbide square end mill engineered for precision milling in ferrous and non-ferrous materials. At 1/4 inch in diameter with a 1/2 inch length of cut and a 30-degree helix angle, this centercutting tool handles slotting, side milling, and plunge operations. The TiCN (Titanium Carbonitride) coating adds surface hardness and lubricity, extending tool life in abrasive cutting environments. Micrograin carbide construction gives this stub-length end mill the rigidity needed for demanding shop-floor applications. The 1/4 inch shank and 2 inch overall length make it compatible with standard collet chucks and milling holders.

This end mill is suited for CNC machining centers and manual milling machines in job shops, tool rooms, and production environments. The 4-flute configuration balances material removal rate with chip evacuation, making it appropriate for finishing and light-to-moderate roughing passes in steel, stainless, cast iron, and similar materials. The right-hand cut and right-hand spiral flutes are the standard configuration for conventional milling setups. Its stub length improves rigidity in setups where deflection and chatter are concerns.

Key Features

• TiCN coating improves wear resistance and surface hardness for longer tool life in abrasive materials
• Solid micrograin carbide construction provides rigidity and edge retention
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 30-degree helix angle balances cutting forces across the flute length
• 4-flute spiral geometry suited for finishing passes and moderate stock removal
• Stub length reduces overhang and minimizes deflection in tight setups

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 on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Secure the shank to the full recommended grip depth in the holder and verify runout before beginning a cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
