Value Collection 720-4118 Square End Mill 7/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4118 is a double-end, four-flute square end mill machined from M2 high speed steel. It is designed for general-purpose milling operations including slotting, profiling, and peripheral cutting in ferrous and non-ferrous materials. The tool features a 7/8 inch cutting diameter with a 1-7/8 inch length of cut, a matching 7/8 inch shank diameter, and a 6-1/8 inch overall length. The 30-degree spiral helix and right-hand cut with right-hand flute geometry promote efficient chip evacuation. This end mill is centercutting, allowing plunge entry directly into a workpiece. It is installed and used by machinists and toolroom professionals on manual mills and CNC machining centers.

This end mill suits a broad range of shop applications including face milling, shoulder milling, and slot cutting in mild steel, aluminum, brass, and similar materials. The double-end configuration extends tool life by offering a second cutting end when the first shows wear, making it well suited for production and job-shop environments where tool economy matters. The bright, uncoated finish is appropriate for use with standard cutting fluids or dry cutting at moderate speeds and feeds.

Key Features

• Double-end design provides two usable cutting ends per tool
• M2 high speed steel construction offers toughness and re-sharpenability
• Centercutting geometry allows direct plunge milling without a pilot hole
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Bright, uncoated finish compatible with a wide range of cutting fluids

Compatibility

Designed as a general-purpose replacement or stock end mill for manual and CNC milling machines accepting a 7/8 inch straight shank tool holder or collet.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in a collet, end mill holder, or Weldon-style holder to the manufacturer-specified engagement depth before initiating any cut. Ensure the spindle is at a complete stop and machine power is locked out before changing or inspecting the tool. Verify runout with a dial indicator after seating to avoid premature tool wear or workpiece dimensional error.
