Hertel E1032902 Square End Mill 1-1/2 in 6 Flute Hss

Product Description

The HERTEL E1032902 is a 6-flute square end mill designed for material removal and finishing operations in ferrous and non-ferrous metals. Manufactured from M7 high speed steel, it features a 1.5 inch cutting diameter, a 2 inch length of cut, and a 4.5 inch overall length with a 1 inch shank diameter. The 30-degree helix angle and right-hand spiral flute geometry promote efficient chip evacuation. This end mill is uncoated and non-centercutting, making it suited for peripheral milling and slotting applications where plunge cutting is not required. Machinists and tool-and-die professionals are the primary installers.

This end mill is used in manual knee mills, CNC machining centers, and horizontal milling setups where a large-diameter, heavy-duty cutter is needed. The 6-flute design increases the number of cutting edges in contact with the workpiece, improving surface finish at appropriate feed rates. It is well-suited for finishing passes on steel, tool steel, and similar materials in both job shop and production environments. The 1 inch shank fits standard R8, CAT, BT, and HSK toolholders sized for 1 inch bore collets or end mill holders.

Key Features

• 1.5 inch cutting diameter with 2 inch length of cut for deep peripheral passes
• 6-flute configuration improves surface finish and supports higher feed rates
• M7 high speed steel construction provides toughness and wear resistance without coating
• 30-degree right-hand spiral flute promotes upward chip flow and reduces heat buildup
• Right-hand cut geometry compatible with standard spindle rotation on conventional milling machines
• Non-centercutting design — not intended for plunge or ramp entry without pre-drilled clearance

Compatibility

Designed as a standard-shank square end mill for use in 1 inch bore end mill holders, collet chucks, and milling arbors on manual and CNC milling machines.

Installation Notes

Installation is performed by a machinist or tool-and-die technician. Power down and lock out the machine spindle before changing tooling. Seat the 1 inch shank fully into the toolholder and torque the retention fastener per the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, and verify that the toolholder bore is clean and free of chips or burrs before seating the shank.
