Hertel EF080024 Square End Mill 3/8 in 2 Flute Hss Ticn

Product Description

The HERTEL EF080024 is a square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from high speed steel (HSS) with a TiCN (Titanium Carbonitride) coating, this 2-flute tool offers a 3/8 inch cutting diameter and a 1-1/2 inch length of cut. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a centercutting design, it is capable of plunge cutting in addition to peripheral and slot milling. Machinists and tool and die professionals working on CNC mills, knee mills, or manual milling machines are the primary users of this tool.

This end mill is suited for use on ferrous and non-ferrous materials where a standard 2-flute geometry is preferred for better chip clearance, particularly in slotting and profiling applications. The 3/8 inch shank diameter matches the cutting diameter, making it compatible with standard ER collet chucks, side-lock holders, and shrink-fit toolholders of the same bore size. The TiCN coating increases surface hardness and reduces friction compared to uncoated HSS, extending tool life in moderate-production environments.

Key Features

• 3/8 inch cutting diameter with matching 3/8 inch shank for straightforward toolholder setup
• TiCN coating improves wear resistance and heat tolerance over uncoated HSS
• 2-flute spiral design provides maximum chip clearance for slotting operations
• 30-degree right-hand helix with right-hand cutting direction for conventional milling setups
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• 3-1/4 inch overall length provides adequate reach for standard milling fixtures

Compatibility

Designed as a standard 3/8 inch shank square end mill compatible with ER collets, set-screw holders, and shrink-fit toolholders bored to 3/8 inch. No specific machine model compatibility is stated by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the toolholder. Verify that the shank is fully seated and the toolholder is torqued to the manufacturer's specification for the holder type in use. Inspect the cutting edges for chips or damage before each use, and do not exceed the recommended depth of cut for the material and machine rigidity.
