Value Collection 720-3045 Square End Mill 1/2 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3045 is a 4-flute, single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Manufactured from M2 high speed steel with a bright/uncoated finish, this tool delivers reliable performance in ferrous and non-ferrous materials. The 1/2 inch cutting diameter and 1-1/4 inch length of cut make it well suited for slotting, peripheral milling, and profile work on manual mills and CNC machining centers. A 30-degree helix angle promotes smooth chip evacuation and consistent cutting action across a range of workpiece materials.

This end mill is intended for use in machine shops, toolrooms, and production environments where a standard fractional-inch HSS end mill is specified. The regular-length geometry and 1/2 inch shank diameter fit standard ER collets and end mill holders commonly found on knee mills, vertical machining centers, and CNC routers. It is appropriate for light to moderate cutting depths in steel, aluminum, brass, and plastics. Machinists, tool and die makers, and CNC operators are the primary users of this tool type.

Key Features

• M2 high speed steel construction provides good wear resistance and toughness across a range of cutting applications
• 4-flute geometry increases feed rate capability and surface finish quality compared to 2-flute designs
• 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Bright/uncoated finish is compatible with a wide range of cutting fluids and lubricants
• Single-end design with right-hand cut and right-hand flute direction for standard spindle rotation
• Non-centercutting construction — not suited for direct plunge entry into solid material

Compatibility

Designed as a standard fractional-inch replacement end mill compatible with any machine tool spindle accepting a 1/2 inch straight shank via collet chuck or end mill holder.

Installation Notes

Installation is performed by a machinist or CNC operator using a properly sized collet or end mill holder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm shank seating depth meets the tool holder manufacturer minimum engagement requirement before tightening. Because this is a non-centercutting end mill, avoid direct axial plunge cuts — use a ramping or helical entry strategy instead.
