Hertel E1035901 Square End Mill 1.25in 6 Flute Hss

Product Description

The HERTEL E1035901 is a 6-flute, high speed steel square end mill designed for milling flat surfaces, slots, and shoulders in ferrous and non-ferrous materials. Built from M7 high speed steel, this single-end tool runs a 30-degree helix angle with right-hand cut and right-hand spiral flutes. The 1.25-inch cutting diameter and 4-inch length of cut suit medium-to-heavy stock removal passes in production and job-shop environments. Machinists and tool-and-die technicians are the primary installers and operators. The uncoated finish makes it a straightforward choice where regrinding is part of the shop workflow.

This end mill is suited to vertical machining centers, manual knee mills, and horizontal mills where a 1-inch straight shank can be held in a collet, end mill holder, or Weldon-flat holder. The 6.5-inch overall length provides reach for deeper setups without excessive overhang. The non-centercutting geometry means this tool is intended for peripheral milling and slotting entries from the side, not for plunge drilling. It is a standard production choice for steel, cast iron, and aluminum applications where an uncoated M7 HSS tool is specified.

Key Features

• M7 high speed steel construction for toughness and regrindability
• 6 spiral flutes with 30-degree helix angle for efficient chip evacuation
• 1.25-inch mill diameter with 4-inch length of cut for medium-depth passes
• Right-hand cut, right-hand flute geometry — standard CNC and manual mill compatible
• Non-centercutting design — side entry and peripheral milling applications
• Uncoated finish — compatible with standard HSS regrinding services

Compatibility

Designed as an OEM-style replacement or direct-use square end mill for machines accepting a 1-inch straight shank in standard end mill holders, collet chucks, or Weldon-style holders on vertical or horizontal milling equipment.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank to the full recommended engagement depth in the holder and verify runout before cutting. Follow applicable shop safety standards and machine manufacturer guidelines for tool holding and speed-and-feed selection for M7 HSS at the given diameter.
