Hertel E1050054 Square End Mill 27/32 in 2 Flute Hss

Product Description

The HERTEL E1050054 is a double-end, square-profile end mill designed for general-purpose milling in ferrous and non-ferrous materials. It is manufactured from high speed steel (HSS) and left uncoated, making it well suited for applications where regrinding and resharpening are part of the shop workflow. The cutter measures 27/32 inches (0.8438 inches) in diameter with a 1-9/16-inch length of cut and a matching 7/8-inch shank diameter. With only 2 flutes, it provides excellent chip clearance in softer materials and slotting operations. The right-hand cut, right-hand spiral flute geometry promotes efficient chip evacuation and stable cutting action.

This end mill is suited for manual mills, CNC machining centers, and knee mills in job shops, maintenance departments, and tool rooms. Its centercutting capability allows it to plunge directly into the workpiece without a pre-drilled starting hole, expanding its utility in pocket milling and die work. The double-end design doubles usable tool life before the cutter is retired or sent for regrinding, a practical advantage in high-volume or cost-conscious environments. Machinists, tool-and-die makers, and maintenance technicians are the typical users.

Key Features

• Centercutting geometry allows direct plunge entry without a pilot hole
• Double-end design provides two cutting ends, extending tool life before replacement
• High speed steel construction supports regrinding and resharpening in the field
• 2-flute configuration maximizes chip clearance in slots and softer workpiece materials
• Right-hand cut with right-hand spiral flute for conventional milling setups
• Uncoated finish simplifies resharpening and reduces tooling cost

Compatibility

Designed as a standard straight-shank end mill compatible with 7/8-inch collets, end mill holders, and Weldon-style side-lock holders used on manual mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the holder and verify runout with a dial indicator before beginning a cut. Follow the machine manufacturer and tooling supplier recommendations for feed rates and spindle speeds appropriate to the workpiece material.
