Hertel 750003 Square End Mill 5/32 in 3 Flute Carbide

Product Description

The HERTEL 750003 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. With a 5/32 inch (0.1563 inch) cutting diameter and a 9/16 inch (0.5625 inch) length of cut, this single-end tool handles slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The micrograin carbide construction provides rigidity and edge retention at higher cutting speeds. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This tool is installed and operated by machinists and CNC operators working in job shops, tool rooms, and production environments.

The 750003 suits regular-length milling work where a compact, rigid setup is needed. The 3/16 inch shank diameter fits standard collets and end mill holders used on vertical machining centers, knee mills, and CNC routers. Its 2 inch overall length keeps deflection low during light-to-medium stock removal passes. The centercutting capability allows plunge entry directly into the workpiece, expanding its use in pocket milling and ramping operations. No extended reach is built into this design, making it best suited for open-face and shallow-pocket work.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• 3 flutes with right-hand cut and right-hand flute direction
• 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Bright/uncoated finish suits a wide range of general-purpose materials
• Regular length (2 inch OAL) minimizes deflection in shallow milling operations

Compatibility

Designed for use with standard 3/16 inch collets and end mill holders on vertical machining centers, knee mills, and compatible CNC milling equipment.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Seat the shank fully into the collet or end mill holder and torque the retention hardware to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before each use, as carbide tools are brittle and should not be used if the edge is compromised.
