Value Collection 720-3069 Square End Mill 3/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3069 is a single-end, 4-flute square end mill machined from M2 high speed steel (HSS). It carries a 3/4-inch cutting diameter with a 1-5/8-inch length of cut and a 3-3/4-inch overall length. The bright, uncoated finish leaves the steel in its natural state, which suits general-purpose milling operations where re-sharpening is a priority. The 30-degree helix angle and right-hand spiral flute geometry support efficient chip evacuation on ferrous and non-ferrous workpiece materials. This tool is sized for standard milling machines and CNC machining centers used in job shops, maintenance shops, and production environments.

This end mill fits standard 3/4-inch diameter toolholders including collet chucks, end mill holders, and Weldon-style holders. It is suited for slotting, profiling, and peripheral milling in a regular-length reach configuration. Applications include milling mild steel, alloy steel, aluminum, brass, and similar machinable materials at conventional cutting speeds. The non-centercutting geometry means it is not intended for direct plunge cutting into solid material without a pre-drilled entry point.

Key Features

• M2 high speed steel construction for durability and resharpening capability
• 4-flute design provides a good balance of chip clearance and surface finish
• 30-degree helix angle promotes smooth cutting and efficient chip evacuation
• Bright, uncoated finish suitable for general-purpose milling and regrinding
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Regular-length configuration keeps overhang minimal for improved rigidity

Compatibility

Designed for use in standard 3/4-inch diameter toolholding systems on vertical milling machines and CNC machining centers. Compatible with collet chucks, end mill holders, and Weldon-flat holders accepting a 3/4-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out. Ensure the shank is seated to the full grip depth recommended by the toolholder manufacturer before torquing set screws or collet nuts. Inspect the toolholder bore and shank for chips or burrs before seating. Because this end mill is non-centercutting, pre-drill or ramp-entry techniques must be used when initiating a pocket or slot from solid material.
