Hertel E8032903 Square End Mill 1-1/8 in 6 Flute Hss

Product Description

The HERTEL E8032903 is a 6-flute square end mill designed for milling operations in ferrous and non-ferrous metals. Built from high speed steel (HSS) with a titanium nitride (TiN) finish, it provides improved surface hardness and extended tool life compared to uncoated HSS tooling. The cutter measures 1.125 inches in diameter with a 2-inch length of cut and mounts on a 1-inch shank. Overall length is 4.5 inches. This is a single-end tool, meaning the cutting geometry is on one end only. It is suited for face milling, slotting, and peripheral milling in manual and CNC machining centers.

This end mill is intended for use in machine shop environments, tool rooms, and production milling applications where HSS tooling is specified. The 6-flute design increases the number of cutting edges in contact with the workpiece, which improves finish quality and allows for higher feed rates at moderate depths of cut. This tool is typically used by machinists and tool-and-die technicians on vertical milling machines and CNC machining centers requiring a 1-inch straight shank. It is not center-cutting, so it is not suited for direct plunge operations.

Key Features

• 1.125-inch milling diameter with a 2-inch length of cut for medium-depth milling passes
• 6-flute geometry improves surface finish and supports higher feed rates compared to 4-flute tooling
• High speed steel construction provides toughness in interrupted cuts and lower-speed machining
• TiN coating increases surface hardness and reduces heat buildup at the cutting edge
• 1-inch shank diameter fits standard ER and side-lock tool holders common to CNC and manual mills
• Non-center-cutting design — requires a pre-drilled hole or ramping entry for pocket operations

Compatibility

Designed for use in milling machines and CNC machining centers equipped with tool holders accepting a 1-inch straight shank. Suitable for slotting, profiling, and face milling applications in HSS-compatible cutting conditions.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before loading or unloading the tool. Seat the shank fully into the tool holder collet or end mill holder and torque the retention hardware to the tool holder manufacturer's specification. Confirm runout with a dial indicator before commencing the cut, as excessive runout will accelerate wear on all six flutes.
