Value Collection 720-3505 Square End Mill 3/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3505 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M2 high speed steel with a bright/uncoated finish, this end mill has a 3/8 inch diameter and a 1-1/2 inch length of cut, making it suited for slotting, profiling, and peripheral milling tasks. The 4-flute geometry and 30-degree right-hand spiral helix provide a balance of chip evacuation and surface finish quality. It is installed and operated by machinists and tool-and-die professionals in both manual and CNC mill setups.

This end mill is appropriate for cutting ferrous and non-ferrous materials in light to medium milling applications. The long-length designation and 3/8 inch shank diameter make it a practical choice when additional reach is needed beyond a standard-length tool. The bright/uncoated finish suits dry cutting and general-purpose use where specialized coatings are not required. Right-hand cutting direction conforms to the majority of conventional vertical milling machine and machining center setups.

Key Features

• 3/8 inch milling diameter with matching 3/8 inch shank diameter for direct collet mounting
• 1-1/2 inch length of cut for deeper slotting and profiling passes
• 4-flute, right-hand spiral configuration at 30-degree helix angle
• M2 high speed steel construction for durability across a range of workpiece materials
• Bright/uncoated finish — no coating buildup concerns during regrinding
• Single-end design; non-centercutting — not intended for direct plunge entry

Compatibility

Designed as a standard fractional-inch shank end mill compatible with 3/8 inch collets, end mill holders, and milling chucks used in vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a qualified machinist. Secure the shank in a matched 3/8 inch collet or end mill holder and verify runout before cutting. Because this tool is non-centercutting, avoid direct axial plunge cuts — use a ramping or helical entry strategy instead. Inspect the cutting edges for wear or chipping before each use and replace the tool when deflection or surface finish degradation is observed.
