Value Collection 720-8200 Square End Mill 20mm 4 Flute Hss

Product Description

The VALUE COLLECTION 720-8200 is a single-end, 4-flute square end mill manufactured from M2 high speed steel (HSS). It is designed for milling, slotting, and profiling operations on a wide range of metals and engineering materials. The cutter diameter is 20 mm (0.7874 inches), with a length of cut of 1.875 inches and an overall length of 4.125 inches. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish is standard for general-purpose HSS tooling. This end mill is installed and operated by machinists and tool-and-die professionals on vertical mills, CNC machining centers, and manual knee mills.

This end mill is suited for general-purpose milling in job shops, maintenance facilities, and production environments. The 20 mm cutter diameter and 1.875-inch length of cut make it appropriate for full-slot and peripheral milling passes at moderate depths. The 3/4-inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style holders common across vertical and horizontal milling setups. It is centercutting, allowing direct plunge entry into the workpiece without a pre-drilled pilot hole.

Compatibility

Designed as a general-purpose replacement or working-stock square end mill for standard milling machines and CNC machining centers accepting a 3/4-inch shank. Part of the VCCC-HSS-4 series.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the milling machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank to the full recommended insertion depth in the toolholder to prevent pullout under cutting load. Verify runout with a dial indicator after installation and before beginning a cut.
