Hertel 750700 Square End Mill 0.25in 4 Flute Solid Carbide

Product Description

The HERTEL 750700 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite materials. With a 0.25-inch cutting diameter, a 1.5-inch length of cut, and a 6-inch overall length, this tool is built for extended-reach applications that require rigidity and edge retention. The 4-flute geometry with a 30-degree spiral helix promotes efficient chip evacuation and smooth surface finishes. A TiN (titanium nitride) finish extends tool life by reducing friction and heat buildup at the cutting edge. This end mill is centercutting, allowing direct plunge entry without a pre-drilled hole.

This end mill is suited for vertical machining centers, CNC mills, and manual knee mills used in job shops, toolrooms, and production environments. It fits standard 0.25-inch collets and tool holders, making it a direct drop-in for setups already running quarter-inch tooling. Right-hand cut orientation makes it compatible with conventional spindle rotation. Typical applications include slotting, profiling, and peripheral milling in ferrous and non-ferrous metals.

Key Features

• Solid carbide construction for high rigidity and wear resistance in demanding cuts
• 4 flutes with 30-degree helix angle for balanced chip evacuation and surface finish quality
• TiN coating reduces friction and extends cutting edge life
• Centercutting design allows plunge milling without a pilot hole
• Right-hand cut, spiral flute geometry compatible with standard CNC and manual mill spindles
• 0.25-inch shank diameter fits common collet systems without adapters

Compatibility

Designed as an OEM-style replacement or direct substitute for 0.25-inch square end mills used in standard collet-style tool holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or tool holder and torque the drawbar or collet nut to the machine manufacturer's specification. Inspect the cutting edges for chips or damage before each use; a damaged edge on solid carbide can fracture unexpectedly under load.
