Hertel 750081 Square End Mill 0.25in 2 Flute Solid Carbide

Product Description

The HERTEL 750081 is a solid carbide square end mill designed for precise milling operations in metal, composite, and engineering plastic workpiece materials. With a 0.25-inch cutting diameter, a 1.5-inch length of cut, and a 4-inch overall length, this tool delivers consistent material removal in a compact, rigid form factor. The 2-flute geometry promotes efficient chip evacuation, and the 30-degree spiral helix angle balances cutting pressure with surface finish quality. Machinists and CNC operators use this end mill for slotting, profiling, and peripheral milling in production and job-shop environments.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills equipped with a 0.25-inch collet or ER-style toolholder. The centercutting design allows plunge entry directly into the workpiece, eliminating the need for a pre-drilled pilot hole in many applications. Right-hand cut and right-hand spiral flute direction are standard for conventional CNC spindle rotation. The single-end, uncoated solid carbide construction is appropriate for shops that rely on regrinding programs or prefer uncoated tools for specific material applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 2-flute design promotes chip clearance in slotting and deep-pocket operations
• 30-degree helix angle balances cutting forces and surface finish
• Centercutting geometry allows direct plunge milling without a pilot hole
• Right-hand cut with spiral flute for standard CNC spindle compatibility
• Uncoated finish suitable for regrinding or material-specific applications

Compatibility

Designed for use in any 0.25-inch collet, ER collet chuck, or end mill holder with a 0.25-inch bore. Compatible with standard CNC machining centers and manual mills running right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in E-stop before changing tooling. Seat the 0.25-inch shank fully into the collet or holder to the recommended engagement depth and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a cut to protect both the tool and the workpiece.
