Hertel 750305 Square End Mill 11/16 in 4 Flute Carbide

Product Description

The HERTEL 750305 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. With an 11/16-inch (0.6875-inch) mill diameter and a 3-inch length of cut, it delivers clean, flat-bottomed profiles in a single pass. The four-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation while maintaining a stable cutting edge. Micrograin carbide construction provides the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. It is a single-end, centercutting tool with a bright, uncoated finish.

This end mill is suited for general-purpose milling tasks including slotting, profiling, and pocketing on CNC machining centers and manual mills. The regular-length geometry and 3/4-inch shank diameter make it compatible with standard ER and side-lock toolholders commonly found in job shops and production environments. It is intended for use by machinists and CNC operators working on steel, aluminum, cast iron, and similar materials where a reliable, consistent cut is required.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 4-flute, right-hand spiral with 30-degree helix for efficient chip evacuation
• Centercutting design allows plunge entry into workpiece material
• 3-inch length of cut suits deep slotting and pocket milling
• Bright, uncoated finish for use across a broad range of materials
• Single-end tool with 3/4-inch shank for rigid toolholder fit

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard CNC and manual milling machine toolholders accepting a 3/4-inch shank diameter.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before changing tooling. Seat the shank fully in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, and confirm spindle speed and feed rate are appropriate for the workpiece material and depth of cut.
