Hertel E2053024 Square End Mill 0.375 in 4 Flute Cobalt

Product Description

The HERTEL E2053024 is a cobalt square end mill designed for milling, slotting, and profiling operations on ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance in demanding cutting environments. The double-end design provides two usable cutting ends, extending tool life between changeovers. With a 0.375-inch diameter, 4-flute configuration, and 30-degree helix angle, this end mill balances chip evacuation with cutting edge strength. The spiral flute geometry and centercutting capability allow both peripheral and plunge cutting. It is an uncoated, right-hand cut tool with right-hand flute direction, weighing 0.1 pounds.

This end mill is suited for use in manual mills, CNC machining centers, and knee mills in job shop, toolroom, and production environments. Machinists and tool-and-die professionals use this style of end mill for general-purpose milling tasks including face milling, side milling, and full-slot cutting. The regular length classification makes it appropriate for standard reach applications where rigidity is a priority over extended projection.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully powered down and locked before inserting or removing the end mill. Use a properly sized collet or end mill holder torqued to the machine tool manufacturer's specification to prevent slippage. Inspect the cutting edges for wear or chipping before each use.
