Hertel 750449 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The HERTEL 750449 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. The tool features a 0.25-inch mill diameter, a 1.25-inch length of cut, and a 2.5-inch overall length. Built from micrograin solid carbide, it delivers rigidity and edge retention under demanding cutting conditions. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Centercutting geometry allows plunge milling in addition to peripheral and slot milling. This end mill is installed and used by machinists and CNC operators in production and job-shop environments.

This end mill is suited for slotting, profiling, and plunge cutting operations on mills and machining centers. The extra-long length-of-cut classification makes it appropriate for deeper cavity work where standard-length tools cannot reach. The 0.25-inch shank diameter fits standard ER collets and end mill holders common in both manual and CNC milling setups. Right-hand cut and right-hand flute direction are standard for conventional milling center configurations. The uncoated finish makes it a cost-effective choice for aluminum, brass, and other non-ferrous materials as well as softer steels.

Key Features

• Micrograin solid carbide construction for improved hardness and edge retention
• 30-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design enables direct plunge entry without pre-drilling
• 2-flute configuration maximizes chip clearance in softer materials and slots
• Extra-long length of cut at 1.25 inches suits deeper cavity and reach applications
• Right-hand cut, right-hand flute, uncoated for versatile general-purpose use

Compatibility

Designed as a direct-fit replacement or standard tooling option for any milling setup accepting a 0.25-inch shank diameter via ER collet, end mill holder, or equivalent toolholding system.

Installation Notes

Install and torque toolholders according to the machine manufacturer specifications and the toolholder manufacturer guidelines. Verify shank runout with a dial indicator before production cutting. Power down and lock out the spindle before changing or adjusting tooling. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine rigidity.
