Value Collection 720-3605 Square End Mill 3/8in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3605 is a single-end square end mill designed for milling, slotting, and profiling operations in ferrous and non-ferrous materials. Manufactured from M2 high speed steel with a bright, uncoated finish, this tool features a 3/8 inch cutting diameter and four spiral flutes arranged in a right-hand cutting and right-hand flute direction. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 4.25 inches overall length with a 2.5 inch length of cut, this is an extra-long configuration suited for jobs requiring reach beyond standard end mill geometry. Installation and use are limited to machinists and CNC or manual mill operators working in a shop environment.

This end mill is appropriate for light-to-moderate material removal on manual knee mills, vertical machining centers, and CNC milling machines. The extra-long reach makes it well suited for deep cavity work, stepped features, and applications where a standard-length tool cannot access the cutting zone. The bright, uncoated finish works best in lower-speed cutting conditions or where tool coating is not required by the material or process. This is a single-end tool, meaning it is not reversible and should be replaced once the cutting edge is worn.

Key Features

• M2 high speed steel construction for reliable performance in general-purpose milling applications
• 3/8 inch cutting diameter with matching 3/8 inch shank for direct collet or end mill holder fitment
• 2.5 inch length of cut provides extended reach for deep-pocket and cavity milling
• Four spiral flutes with 30-degree helix angle for effective chip evacuation
• Right-hand cut and right-hand flute direction — standard orientation for conventional milling setups
• Bright, uncoated finish — no thermal barrier coating, suitable for dry or light-flood cutting conditions

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist familiar with milling machine tooling and setup procedures. Power down and lock out the spindle drive before inserting or removing the tool. Ensure the shank is fully seated and properly clamped in the collet or tool holder to the holder manufacturer's specified torque range. Verify spindle speed and feed rate are appropriate for the work material before engaging the cut — this tool is not centercutting and should not be plunged axially into solid material.
