Hertel E1035108 Square End Mill 1-1/8 in 6 Flute Hss

Product Description

The HERTEL E1035108 is a single-end, square-profile end mill designed for milling operations on machining centers and manual mills. It features a 1-1/8 inch cutting diameter, a 4 inch length of cut, and a 1 inch straight shank, giving it a 6-1/2 inch overall length. Constructed from M7 high speed steel in an uncoated finish, this tool is built for general-purpose slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. Six spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. This is a long-series configuration, suited for applications requiring extended reach beyond standard-length tooling.

This end mill is intended for use in production and job-shop environments where a long-reach, large-diameter HSS tool is required. The right-hand cut, right-hand flute geometry is the standard configuration compatible with conventional CNC machining centers, knee mills, and horizontal mills. It is not center-cutting, so it is not intended for direct plunge operations. Typical applications include deep-pocket roughing, shoulder milling, and side milling passes where the 4 inch length of cut provides clearance in deep-walled fixtures or workpieces.

Key Features

• 1-1/8 inch cutting diameter with 4 inch length of cut for deep-reach milling
• Six spiral flutes at a 30-degree helix angle for smooth chip flow and reduced cutting force
• M7 high speed steel construction provides toughness and resistance to edge chipping
• Long-series overall length of 6-1/2 inches with a 1 inch shank for rigid tool holding
• Right-hand cut and right-hand flute direction — standard orientation for most mill setups
• Uncoated finish — suitable for regrinding and compatible with cutting fluid applications

Compatibility

Designed as an OEM-style replacement or direct-application square end mill for use in standard 1 inch collet chucks, end mill holders, or Weldon-style side-lock holders on vertical and horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of burrs before seating the shank. Verify that the 1 inch shank is secured to the full recommended engagement depth in the holder to minimize runout. Because this tool is not center-cutting, avoid direct plunge cuts — use ramping or helical interpolation entry strategies instead.
