Hertel E1037132 Square End Mill 1.5in 6 Flute Hss Extra Long

Product Description

The HERTEL E1037132 is a square end mill engineered for demanding material removal in metal cutting applications. Built from M7 high speed steel in an uncoated finish, this tool features a 1.5-inch cutting diameter, six spiral flutes with a 30-degree helix angle, and a right-hand cut with right-hand flute orientation. The extra-long configuration provides 8 inches of length of cut and a 10.5-inch overall length, making it well suited for deep-pocket milling and extended-reach operations where standard-length end mills fall short. Weighing 3.55 pounds, it mounts via a 1.25-inch straight shank.

This end mill is intended for professional machinists and toolroom operators working with steel, cast iron, and similar ferrous materials on manual mills and CNC machining centers. The extra-long reach is especially useful in mold and die work, aerospace fixturing, and any application requiring access to deep cavities or tall workpieces. The six-flute design supports higher feed rates in finishing and semi-finishing passes where chip load per tooth is moderate.

Key Features

• M7 high speed steel construction for durability in ferrous metal cutting
• Six spiral flutes with 30-degree helix angle for efficient chip evacuation
• Extra-long 8-inch length of cut for deep-pocket and extended-reach operations
• Right-hand cut and right-hand flute orientation, standard for most milling setups
• Uncoated finish suitable for use with cutting fluids and coolants
• Non-centercutting design — requires a pre-drilled or pre-milled entry point

Compatibility

Designed as a general-purpose square end mill for use in standard and CNC vertical milling machines accepting a 1.25-inch straight shank via collet, end mill holder, or hydraulic chuck.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the tool. Seat the shank fully into the holder to the recommended engagement depth and torque set screws per the holder manufacturer specifications. Because this is a non-centercutting end mill, always pre-drill or plunge with an appropriate center-cutting tool before engaging this end mill in a closed pocket.
