Value Collection 720-3203 Square End Mill 3/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3203 is a single-end square end mill designed for general-purpose milling operations in metal and non-ferrous materials. Manufactured from M2 high speed steel with a bright/uncoated finish, it features a 3/16 inch cutting diameter and four spiral flutes with a 30-degree helix angle. The centercutting geometry allows plunge entry into the workpiece, adding versatility to slotting, profiling, and pocket-milling applications. This tool is suited for use in manual mills, CNC machining centers, and drill presses with milling capability. Machinists and tool-and-die professionals are the primary users of this style of end mill.

This end mill is built to the regular length standard, with a 1/2 inch length of cut and a 2-3/8 inch overall length. The 3/8 inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style tool holders. Right-hand cut and right-hand flute configuration make it compatible with conventional spindle rotation on the vast majority of machine tools. It is appropriate for light-to-medium duty milling on ferrous metals, aluminum, brass, and plastics in both job-shop and production environments.

Key Features

• M2 high speed steel construction provides good wear resistance and toughness for general milling applications
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Four-flute, 30-degree spiral helix geometry balances chip evacuation with surface finish quality
• Bright/uncoated finish suitable for use with or without cutting fluid
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Regular length series with no extended reach, supporting rigidity during cuts

Compatibility

Designed as an OEM-style replacement or direct-use single-end square end mill for standard 3/8 inch shank tool holders, ER collet chucks, and Weldon-style holders used in manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and the spindle fully stopped before tool changes. The shank should be seated to the recommended minimum engagement depth in the holder, and the collet nut or set screw should be tightened using the appropriate spanner or hex key before operation. Inspect the cutting edges for chips or damage before each use. Always observe safe speeds and feeds for the workpiece material to prevent tool breakage.
