Hertel E8053048 Square End Mill 3/4in 4 Flute Hss Tin

Product Description

The HERTEL E8053048 is a double-end, square-profile end mill designed for milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel with a titanium nitride (TiN) coating, it provides increased surface hardness and improved wear resistance over uncoated HSS tooling. The cutter measures 3/4 inches in diameter with a 1-5/8 inch length of cut, a matching 3/4 inch shank diameter, and a 5-5/8 inch overall length. Four right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation. Centercutting geometry allows plunge entry as well as conventional side milling and slotting. Machinists and tool-and-die tradespeople use this tool in manual and CNC milling setups.

This end mill is suited for general-purpose milling in job shops, maintenance departments, and production environments. The double-end configuration extends tool life by providing two usable cutting ends before the tool is retired. Right-hand cutting direction is standard for conventional milling machine spindles. The 30-degree helix angle balances cutting forces for stable performance across a range of work materials including mild steel, alloy steel, aluminum, and plastics. Typical applications include profiling, slotting, and peripheral milling at moderate depths of cut.

Key Features

• M7 high speed steel construction for toughness in interrupted and general milling cuts
• TiN coating adds surface hardness and reduces friction at the cutting edge
• Double-end design provides two cutting ends, extending tool service life
• Centercutting capability allows direct plunge entry into workpiece material
• 30-degree right-hand spiral flutes for efficient chip flow and reduced heat buildup
• Four flutes deliver a good balance of chip clearance and surface finish

Compatibility

Designed for use in standard milling machine collet chucks, end mill holders, and CNC tool holders accepting a 3/4 inch straight shank. Compatible with manual knee mills and CNC machining centers running right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter. Seat the shank to the full recommended engagement depth in the holder to prevent pullout under cutting loads. Inspect the cutting edges for chipping or wear before each use, and do not exceed the rated length-of-cut range of 1.5 to 2.0 inches for this tool diameter class.
