Hertel 750045 Square End Mill 5/8 Inch 4 Flute Carbide

Product Description

The HERTEL 750045 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 5/8-inch cutting diameter with a 4-flute, spiral-flute geometry and a 30-degree helix angle. The single-end configuration runs right-hand cut with right-hand flutes, making it compatible with standard vertical and horizontal milling setups. The bright, uncoated finish suits general-purpose use across a range of ferrous and non-ferrous materials. The micrograin carbide substrate provides the edge retention and rigidity needed for consistent performance in production environments. Machinists and CNC operators install this tool in standard 5/8-inch collets or end mill holders.

This end mill fits standard CNC machining centers, knee mills, and manual milling machines where a 5/8-inch shank is required. The centercutting design allows plunge entry, giving the operator flexibility for pocketing, slotting, and profiling operations. With a 3/4-inch length of cut and a 3-inch overall length, it is well suited for shallow-to-mid-depth passes in general production work. The HSQSC4-CC series targets applications demanding consistent geometry and tight tolerances in fractional-inch tooling setups.

Key Features

• Solid micrograin carbide construction for enhanced edge retention and rigidity
• 4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry for pocketing and slotting
• Right-hand cut, right-hand flute configuration for standard milling spindle direction
• Bright, uncoated finish suitable for a wide range of general-purpose materials
• Single-end design in HERTEL HSQSC4-CC series for fractional-inch tooling applications

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/8-inch collet chucks and end mill holders used on CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout specifications. Ensure the spindle is fully stopped and locked before inserting or removing the end mill from the holder. Verify collet size and holder condition before tightening to prevent tool pullout during cutting. Follow applicable shop safety protocols and machine-specific procedures for tool changes.
