Hertel E1030912 Square End Mill 1-3/8 in 2 Flute Hss

Product Description

The HERTEL E1030912 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Manufactured from M7 high speed steel with a bright/uncoated finish, it measures 1.375 inches in diameter with a 1.625-inch length of cut and a 4.125-inch overall length. The 1-inch shank diameter fits standard toolholders and collet chucks common in vertical and horizontal milling setups. With a 30-degree helix angle and right-hand cutting direction, this tool is suited for slotting, profiling, and peripheral milling in production and job shop applications. Installation and use are performed by machinists and tool-and-die professionals.

This end mill is used in ferrous and non-ferrous metal removal operations where a bright, uncoated HSS tool is appropriate. The 2-flute design provides larger chip clearance, making it effective for slotting cuts and applications requiring efficient chip evacuation. The centercutting geometry allows the tool to plunge directly into a workpiece. The regular length classification and fixed helix make it a straightforward choice for standard milling programs on manual or CNC knee mills, bed mills, and machining centers.

Key Features

• M7 high speed steel construction for durability in general-purpose milling
• 1.375-inch mill diameter with 1.625-inch length of cut for substantial material removal
• 2-flute spiral design provides generous chip clearance for slotting operations
• Centercutting capable, allowing direct plunge entry without a pilot hole
• 30-degree right-hand helix with right-hand cutting direction for stable chip flow
• Bright/uncoated finish suitable for use with cutting fluids across a wide range of materials

Compatibility

Designed as a standard single-end square end mill with a 1-inch shank diameter, compatible with toolholders, collet chucks, and end mill holders sized for 1-inch straight shanks on vertical or horizontal milling machines.

Installation Notes

Installation is performed by a qualified machinist. Secure the 1-inch shank firmly in a properly sized collet or end mill holder before operation, and verify runout with a dial indicator prior to cutting. Power down and lock out the spindle before changing or adjusting tooling. Always apply appropriate cutting fluid and observe recommended feed and speed parameters for M7 HSS tooling based on the workpiece material.
