Hertel E8030016 Square End Mill 1/4 in 2 Flute Hss Tin

Product Description

The HERTEL E8030016 is a 2-flute square end mill designed for general-purpose milling operations in a wide range of shop environments. Built from M7 high speed steel with a TiN (titanium nitride) coating, it delivers solid wear resistance and surface hardness for cutting ferrous and non-ferrous materials. The cutter features a 30-degree helix angle with spiral fluting, a right-hand cut, and right-hand flute direction. At 0.25 inches in diameter with a 0.5-inch length of cut and a 3/8-inch shank, this end mill is well suited for slotting, profiling, and light pocket milling where a smaller-diameter tool is required. It weighs approximately 0.1 pounds.

This end mill is used in vertical machining centers, knee mills, and manual or CNC milling machines in job shop, maintenance, and production environments. The centercutting geometry allows direct plunge entry into a workpiece without pre-drilling. The 3/8-inch shank fits standard collets and end mill holders commonly found in both manual and CNC setups. It is typically installed and used by machinists and tool-and-die professionals handling light to medium material removal in steel, aluminum, brass, and similar materials.

Key Features

• M7 high speed steel construction for toughness and wear resistance
• TiN finish increases surface hardness and extends tool life
• 30-degree helix angle with spiral flute geometry for smooth chip evacuation
• Centercutting design allows direct plunge cutting without pre-drilling
• Right-hand cut and right-hand flute direction for standard milling applications
• 2-flute configuration suited for slotting and milling in softer or gummy materials

Compatibility

Designed as an OEM-style replacement or standard tooling selection for milling applications requiring a 1/4-inch diameter, 2-flute square end mill with a 3/8-inch shank in M7 high speed steel.

Installation Notes

This end mill is installed by qualified machinists in a collet or end mill holder sized for a 3/8-inch shank. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Follow shop-standard torque practices when tightening the collet nut — do not over-tighten with a hammer or improvised tools. Confirm runout and tool projection before beginning the cut.
