Hertel 750126 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The HERTEL 750126 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering plastics. It features a 5/16 inch diameter with a 4-flute, right-hand spiral geometry and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate delivers the edge retention and rigidity required for demanding cuts in tough materials. With a 1-1/8 inch length of cut and a 3 inch overall length, this tool is suited for standard-depth slotting, profiling, and peripheral milling tasks performed by machinists and toolroom professionals.

This end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where a 5/16 inch shank fits the collet or holder directly. The centercutting geometry allows plunge entry without a pre-drilled pilot hole, expanding its use in pocketing and ramping operations. The bright uncoated finish is appropriate for non-ferrous metals and general-purpose applications where coating-related heat buildup or adhesion to workpiece material is a concern. It runs as a single-end tool, so once the cutting end is worn, the tool is replaced rather than flipped.

Key Features

• Solid micrograin carbide construction for superior edge retention and rigidity
• 4-flute, right-hand spiral design with 30-degree helix angle for efficient chip flow
• Centercutting geometry enables direct plunge entry and pocketing operations
• Bright uncoated finish suited for non-ferrous metals and general-purpose milling
• Matching 5/16 inch shank and cutter diameter simplifies collet selection
• Single-end configuration; 3 inch overall length fits standard tool holders

Compatibility

Designed for use with 5/16 inch collets or end mill holders on CNC machining centers and manual milling machines. Part of the HERTEL HSQSC4-CC series of solid carbide square end mills.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention hardware per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces surface finish quality.
