Hertel E103013201 Square End Mill 1-1/2 in 2 Flute Hss

Product Description

The HERTEL E103013201 is a square end mill designed for general-purpose milling operations in metal-cutting environments. Built from M7 high speed steel, it features a 1-1/2 inch cutting diameter with a 1-1/2 inch length of cut and a 3/4 inch shank diameter, giving it a rigid profile suited for slotting, profiling, and peripheral milling. The 2-flute configuration promotes chip evacuation in softer metals and non-ferrous materials. With a 30-degree helix angle, right-hand cut, and right-hand spiral flute geometry, this end mill runs in standard spindle-forward rotation on vertical and horizontal milling machines.

This end mill is intended for use in manual mills, CNC machining centers, and knee mills where a large-diameter HSS tool is appropriate. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled hole. Typical applications include roughing and semi-finishing passes on aluminum, brass, mild steel, and similar machinable materials. It is sold individually and is well-suited for machine shops, tool-and-die operations, and maintenance machining environments where HSS tooling is preferred over carbide.

Key Features

• 1-1/2 inch cutting diameter with 1-1/2 inch length of cut for substantial material removal
• M7 high speed steel construction provides toughness and re-sharpenability
• 2-flute spiral design promotes chip clearance in slotting and plunge operations
• 30-degree helix angle balances cutting efficiency with edge strength
• Centercutting geometry enables direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute for standard spindle rotation
• Uncoated finish — compatible with re-sharpening and custom coating workflows

Compatibility

Designed as a standard-geometry square end mill with a 3/4 inch straight shank, compatible with ER, R8, Weldon, and other common 3/4 inch milling tool holders used on vertical and horizontal machining equipment.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware per the tool holder manufacturer's specification. Verify runout at the cutting diameter before beginning production cuts.
