Hertel E1050023 Square End Mill 23/64 Inch 2 Flute Hss

Product Description

The HERTEL E1050023 is a double-end, square-profile end mill designed for milling, slotting, and profiling operations on metal and general-purpose materials. Built from M7 high speed steel, this uncoated tool features a 30-degree spiral flute geometry that promotes efficient chip evacuation and smooth cutting action. With a 23/64-inch cutting diameter and a 9/16-inch length of cut, it handles light to medium material removal in both manual and CNC machining setups. The centercutting design allows plunge entry directly into the workpiece. Two flutes keep the tool rigid at this diameter while maintaining adequate chip clearance. At 0.01 pounds, the tool is lightweight and balanced for precise spindle performance.

This end mill is suited for job shops, tool rooms, and production environments where M7 HSS tooling is preferred over carbide for interrupted cuts or softer workpiece materials. The 3/8-inch shank diameter fits standard ER collets, side-lock holders, and end mill adapters common in vertical mills and CNC machining centers. Its regular-length configuration makes it a practical choice for standard-depth pockets, slots, and peripheral profiles in ferrous and non-ferrous materials.

Key Features

• M7 high speed steel construction provides toughness in interrupted and impact-prone cuts
• Double-end design delivers two usable cutting ends, extending tool life value
• Centercutting geometry enables direct plunge milling without a pre-drilled entry hole
• 30-degree helix angle promotes smooth chip flow and reduces cutting forces
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Uncoated finish suits applications where coating buildup or heat sensitivity is a concern

Compatibility

Designed as a standard replacement or stock end mill for any machine tool accepting a 3/8-inch straight shank, including vertical knee mills, benchtop mills, and CNC machining centers using ER or end mill collet systems.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the spindle fully powered down and locked out before tool changes. Ensure the shank seating depth meets the holder manufacturer's minimum engagement specification. Inspect collet or holder runout before securing the tool to avoid premature edge wear. Follow machine tool manufacturer guidelines and applicable shop safety procedures during setup.
