Hertel 750592 Carbide Square End Mill 0.25in 2 Flute Altin

Product Description

The HERTEL 750592 is a solid carbide square end mill designed for precision metal removal in milling operations. It features a 0.25 inch cutting diameter with a 1.5 inch length of cut, a 0.25 inch shank diameter, and a 4 inch overall length. The two-flute geometry paired with a 30-degree helix angle promotes efficient chip evacuation, making it well suited for slotting, profiling, and pocketing in a range of ferrous and non-ferrous materials. The AlTiN (aluminum titanium nitride) coating extends tool life at elevated cutting temperatures. This end mill is single-end, center-cutting, and right-hand cut, and is installed by machinists and CNC operators in job shop and production environments.

The HERTEL 750592 is used in vertical and horizontal milling machines as well as CNC machining centers. Its center-cutting design allows plunge entry directly into the workpiece, adding versatility to complex part programs. The 0.25 inch diameter and two-flute configuration are commonly applied to fine-detail features, narrow slots, and contour passes in steel, stainless steel, cast iron, and hardened alloys. The AlTiN finish makes it particularly effective in dry or semi-dry cutting conditions where heat buildup is a concern.

Key Features

• 0.25 inch cutting diameter with 1.5 inch length of cut for deep-feature access
• Solid carbide construction provides rigidity and wear resistance over high-speed tool steels
• AlTiN coating resists oxidation and thermal wear in high-temperature cutting environments
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Center-cutting design permits direct plunge milling without pre-drilled entry
• Right-hand cut, single-end configuration compatible with standard ER and end mill holders

Compatibility

Designed as a direct-fit replacement end mill for standard 0.25 inch end mill holders and collet chucks used in CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by machinists using an ER collet chuck, side-lock holder, or shrink-fit toolholder rated for the shank diameter. Ensure the machine spindle is fully stopped and locked before changing tooling. Confirm runout with a dial indicator after seating the tool to avoid premature edge wear. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and coating type.
