Hertel E1036040 Square End Mill 0.625in 4 Flute Hss

Product Description

The HERTEL E1036040 is a single-end, square-profile end mill designed for general milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel, it features a 0.625-inch cutting diameter, a 4-inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. The right-hand cut and right-hand flute orientation suit standard vertical and horizontal milling machine setups. At 6.125 inches overall length with a 0.625-inch straight shank, it fits conventional ER and straight-bore toolholders common in job shop and production environments. Machinists and toolroom technicians are the primary users.

This end mill is suited for peripheral and slot milling passes on mild steel, alloy steel, cast iron, and similar materials where HSS tooling is preferred over carbide. The uncoated finish and non-centercutting geometry mean it is intended for side milling and profiling cuts rather than plunge entry. Typical applications include keyway cutting, shoulder milling, and contour work on manual mills and CNC machining centers operating at speeds appropriate for M7 HSS. The 4-inch length of cut supports deeper cavity work where a shorter end mill would not reach.

Key Features

• M7 high speed steel construction for toughness in interrupted and general-purpose cuts
• 4-flute spiral design improves surface finish and chip evacuation compared to 2-flute geometry
• 30-degree helix angle balances cutting efficiency with tool rigidity
• Right-hand cut, right-hand flute for standard spindle direction compatibility
• Uncoated finish allows easy regrinding and suits oil-based cutting fluid applications
• Non-centercutting design — use for side milling and profiling, not plunge entry

Compatibility

Designed as a standard straight-shank square end mill compatible with ER collet chucks, straight-bore end mill holders, and Weldon-style holders accepting a 0.625-inch shank diameter on vertical mills, knee mills, and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the toolholder to the recommended minimum engagement depth before tightening. Power down and lock out the spindle before changing tooling. Do not use this end mill for plunge cutting, as it is a non-centercutting design; pre-drill or use a ramping entry strategy instead.
