Hertel E1033012 Square End Mill 3/16 in 2 Flute Hss

Product Description

The HERTEL E1033012 is a 2-flute square end mill manufactured from M7 high speed steel. It carries a 3/16-inch cutting diameter with a 1/2-inch length of cut and a 3/8-inch shank diameter, giving the tool a compact profile suited to close-tolerance slotting and peripheral milling. The overall length measures 2-11/16 inches, placing it in the long-length category with a 1-1/8-inch reach. The spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. The tool is uncoated and centercutting, allowing direct plunge entry without a pre-drilled hole. It is installed by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is suited to ferrous and non-ferrous machining operations including slotting, profiling, and pocket milling on steel, aluminum, brass, and similar materials. The long-length configuration extends reach into deeper features where standard-length tools cannot access. The 2-flute design provides generous chip clearance, making it a practical choice for aluminum and softer alloys where chip evacuation is a priority. It is equally usable in light-duty steel applications at appropriate feed and speed parameters.

Key Features

• Centercutting geometry allows direct plunge milling without a starter hole
• M7 high speed steel construction provides toughness for interrupted cuts and manual machining
• 30-degree helix angle spiral flute promotes smooth cutting action and efficient chip evacuation
• Long-length classification with 1-1/8-inch reach extends access into deep pockets and features
• Right-hand cut, right-hand flute orientation for standard spindle rotation on conventional and CNC mills
• Uncoated finish maintains sharp edge geometry for regrinding and resharpening

Compatibility

Designed as a general-purpose replacement or stock end mill for manual knee mills and CNC machining centers accepting a 3/8-inch straight shank. Verify spindle collet or end mill holder bore matches the 3/8-inch shank diameter before installation.

Installation Notes

A licensed machinist or qualified shop technician should install and operate this tool. Power down and lock out the spindle drive before securing or changing the end mill in the holder or collet. Confirm shank seating depth meets the tool holder manufacturer minimum engagement requirement. Do not exceed the tool manufacturer recommended feeds and speeds for the work material.
