Value Collection 720-3201 Square End Mill 1/8in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3201 is a single-end square end mill designed for precision milling operations in metal and general-purpose machining environments. Manufactured from M2 high speed steel with a bright/uncoated finish, this tool features a 1/8 inch cutting diameter and a 3/8 inch length of cut, making it well suited for light slotting, profiling, and peripheral milling passes. With four flutes and a 30-degree helix angle in a right-hand cutting direction, it delivers efficient chip evacuation and clean edge geometry on a variety of workpiece materials. The 3/8 inch shank diameter and 2-5/16 inch overall length fit standard tool holders used in CNC mills, manual knee mills, and machining centers.

This end mill is appropriate for job shops, tool rooms, and maintenance machining applications where small-diameter, fine-detail work is required. The regular-length designation and fractional inch sizing make it a common selection for setups involving aluminum, mild steel, brass, and plastics. It is a single-end tool, so the cutting end is not reversible, and it should be replaced once the cutting edges show wear rather than reground for reuse in most shop contexts.

Key Features

• M2 high speed steel construction for hardness and wear resistance in general-purpose machining
• Four flutes with a 30-degree right-hand helix for efficient chip flow and smooth finishes
• 1/8 inch cutting diameter with a 3/8 inch length of cut for fine detail and slot work
• Center-cutting geometry allows plunge entry as well as peripheral and slot milling
• Bright/uncoated finish suitable for use with standard cutting fluids or dry on non-ferrous materials
• Regular-length, fractional inch sizing for compatibility with standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement or standard shop-stock end mill compatible with any machine tool spindle accepting a 3/8 inch shank in a collet, end mill holder, or set-screw adapter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with proper tool holding procedures. Ensure the machine spindle is fully powered down and locked out before inserting or removing the end mill from its holder. Set tool projection to the minimum length necessary for the operation to maximize rigidity and reduce deflection risk. Verify runout at the cutting diameter after clamping before initiating a cut.
