Hertel E199921286 Square End Mill 13/32 in 2 Flute Hss

Product Description

The HERTEL E199921286 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. It features a 13/32 inch (0.4063 inch) cutting diameter with a 1-3/4 inch length of cut, providing solid material removal in slots, pockets, and peripheral milling applications. Constructed from high speed steel (HSS), this end mill offers good toughness and grindability. The bright, uncoated finish is suitable for a range of workpiece materials where coating is not required. This tool is installed and used by machinists and tool-and-die professionals in manual and CNC milling setups.

This end mill is suited for light-to-medium duty milling in ferrous and non-ferrous materials. The 2-flute configuration provides good chip evacuation, making it a practical choice for slotting and plunge cuts in softer steels, aluminum, brass, and similar materials. With a 1/2 inch shank diameter and a 3-3/4 inch overall length, it fits standard ER and R8 collet systems common in knee mills, bridgeport-style machines, and CNC machining centers used in job shops and maintenance operations.

Key Features

• 13/32 inch (0.4063 inch) cutting diameter for precise slot and pocket milling
• 2-flute spiral design promotes chip evacuation, suited for slotting and plunge operations
• 30-degree right-hand helix with right-hand cutting direction for standard milling setups
• Centercutting geometry allows direct plunge entry without a pilot hole
• High speed steel construction provides toughness and easy resharpening in the field
• Bright uncoated finish — no additional coating to account for in speed and feed calculations

Compatibility

Designed as an OEM-style replacement or standard tooling option for 1/2 inch collet or chuck setups on knee mills, CNC vertical machining centers, and similar milling equipment requiring a 13/32 inch square end mill.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and at rest before changing tooling. Secure the shank in a properly sized collet or end mill holder torqued to the machine manufacturer specification, and verify runout with a dial indicator before engaging the workpiece. Follow applicable shop safety procedures and refer to the machine tool manual for speed and feed guidelines appropriate to the workpiece material.
