Hertel E1052024 Square End Mill 3/8 in 3 Flute Hss

Product Description

The HERTEL E1052024 is a double-end, square-profile end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel and left uncoated, this tool delivers consistent cutting performance without the added cost of a coating. It runs a 3/8 inch cutting diameter with a 3/4 inch length of cut, a 30-degree helix angle, and a right-hand cut with right-hand spiral flutes. The centercutting geometry allows direct plunge entry into the workpiece. Machinists and tool and die professionals working on CNC mills, manual knee mills, or bridgeport-style machines will find this a dependable choice for slotting, profiling, and step milling.

This end mill suits light to moderate material removal in shop and production environments. The 3-flute configuration balances chip evacuation and surface finish, making it effective on aluminum, mild steel, and similar machinable alloys. The double-end design extends tool life by providing a second cutting end once the first is worn. At 3-1/2 inches overall length with a 3/8 inch shank diameter, it fits standard ER and straight-bore collet systems commonly found in vertical machining centers and manual mills.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general-purpose milling
• Double-end design doubles usable tool life per unit
• 3-flute spiral flute geometry improves chip flow and finish quality
• 30-degree helix angle supports smooth cutting action and reduced chatter
• Centercutting capability allows direct plunge milling without a pilot hole
• Uncoated finish suits applications where coating is not required or where regrinding is anticipated

Compatibility

Designed as a standard OEM-style replacement or direct-use end mill for vertical milling machines and CNC machining centers that accept 3/8 inch straight shank tooling in ER collets or straight-bore holders.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention nut to the tool holder specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and degrades surface finish.
