Value Collection 720-3223 Square End Mill 1-1/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3223 is a 4-flute, single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Built from M2 high speed steel with a bright uncoated finish, it cuts at a 30-degree helix angle with right-hand cut and right-hand flute spiral geometry. The 1.125-inch mill diameter and 2-inch length of cut make it well-suited for slotting, profiling, and peripheral milling where a standard-reach tool is appropriate. Machinists and tool-and-die professionals install this end mill in manual mills and CNC machining centers requiring a 1-inch straight shank.

This end mill fits typical production and job-shop milling applications where a regular-length, fractional-inch HSS tool is specified. The centercutting design allows direct plunge entry into workpiece material, adding versatility for interpolated pocketing and ramp entry operations. It is appropriate for use on steel, cast iron, aluminum, and similar materials within the cutting-speed range typical of M2 HSS tooling. No coolant-through capability is present, so flood or mist coolant applied externally is the standard approach for heat management during cuts.

Key Features

• M2 high speed steel construction provides a balance of wear resistance and toughness for general machining
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge milling without a pre-drilled pilot hole
• Bright uncoated finish suits a wide range of materials without coating compatibility concerns
• Right-hand cut and right-hand spiral flute — standard orientation for conventional milling setups
• Single-end design; when the cutting end is worn, the tool is replaced rather than flipped

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for manual knee mills and CNC machining centers accepting a 1-inch straight shank, regular-length 4-flute square end mill in fractional-inch sizing.

Installation Notes

Installation is performed by a qualified machinist following shop safety procedures. The shank must be fully seated and clamped in a properly sized collet or end mill holder rated for the 1-inch shank diameter before spindle operation. Verify spindle RPM and feed rate against M2 HSS cutting-speed charts for the workpiece material before engaging the cut. Inspect the tool holder and drawbar torque per machine manufacturer specifications before each use.
