Value Collection 320-0003 Square End Mill Set 10 Pc Hss

Product Description

The VALUE COLLECTION 320-0003 is a 10-piece square end mill set made from M2 high speed steel with a titanium nitride (TiN) coating. Single-end geometry delivers clean, flat-bottom cuts in a wide range of materials including aluminum, mild steel, plastics, and wood. The TiN finish increases surface hardness and reduces friction, extending tool life compared to uncoated HSS. Each mill is ground to a square end profile suited for slotting, profiling, and facing operations. The set stores in an included wood case, keeping cutters organized and protected between uses. Machinists and toolroom technicians working on manual mills or CNC machines are the typical users.

This set covers five common cutter diameters — 1/4 inch, 3/8 inch, 1/2 inch, 5/8 inch, and 3/4 inch — providing two mills per diameter for productive shop use. It is well suited for general-purpose milling work in job shops, maintenance departments, trade schools, and light production environments. The square end profile makes it appropriate for peripheral milling, step milling, and pocket roughing where a flat floor is required. Non-roughing geometry means these mills are intended for standard feed rates rather than high-chip-load aggressive cuts.

Key Features

• M2 high speed steel construction for durability across a broad range of work materials
• Titanium nitride (TiN) coating increases hardness and reduces tool wear
• Square end geometry for slotting, profiling, and flat-floor pocketing
• Single-end design — 10 mills covering five diameters from 1/4 inch to 3/4 inch
• Includes wood storage case to protect cutting edges and keep the set organized

Compatibility

Designed as a general-purpose replacement or starter set for standard end mill holders and collet chucks used on vertical milling machines and CNC machining centers accepting straight-shank end mills.

Installation Notes

End mills are installed by a machinist or toolroom technician using an appropriate collet, end mill holder, or set-screw holder sized to match the cutter shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Inspect each cutting edge for chips or damage before use. Follow machine manufacturer torque guidelines when tightening collet nuts or set screws to prevent tool pullout during cutting.
