Value Collection 720-3205 Square End Mill 1/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3205 is a single-end, square-profile end mill designed for general-purpose milling operations in metal, plastic, and composite materials. It is manufactured from M2 high speed steel with a bright/uncoated finish and features a 4-flute, spiral-flute geometry with a 30-degree helix angle. The 1/4-inch cutting diameter and 5/8-inch length of cut make it well suited for slotting, profiling, and light peripheral milling. At 0.06 pounds, this is a compact tool intended for standard-reach applications without extended reach requirements. Machinists and toolroom technicians working on manual mills, knee mills, and CNC machining centers are the primary users.

This end mill fits standard toolholding in machines configured for a 3/8-inch shank diameter. The 2.5-inch overall length keeps it rigid in typical setups. The right-hand cutting direction and right-hand flute spiral are the conventional configuration found on most vertical milling setups. It is suited for finishing and light roughing cuts in applications where HSS tooling is preferred over carbide, such as softer steels, aluminum, and non-ferrous metals. Centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• M2 high speed steel construction provides toughness and resharpening capability
• 4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling without a pilot hole
• Bright/uncoated finish suitable for use with or without cutting fluid
• Right-hand cut and right-hand flute configuration for standard vertical mill setups
• Regular-length (non-extended-reach) body maintains rigidity during cut

Compatibility

Designed as a standard fractional-inch shank end mill for use in collet chucks, end mill holders, and other toolholding systems accepting a 3/8-inch shank diameter on manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully and evenly in the holder and torque set screws according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before use and confirm runout is within acceptable limits for the application.
