Osg 6602100 Square End Mill 5/8 Inch 3 Flute Powdered Metal

Product Description

The OSG 6602100 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from powdered metal, it delivers consistent edge hardness and wear resistance across the cutting zone. The tool runs a 0.625-inch mill diameter with a 1.625-inch length of cut, a matching 0.625-inch shank diameter, and a 3.75-inch overall length. The 3-flute design combined with a 50-degree helix angle promotes aggressive chip evacuation and smooth cutting action, making it well suited for slotting, peripheral milling, and light profiling in a CNC or manual milling environment.

This end mill fits into standard collet chucks and end mill holders accepting a 0.625-inch shank. The Series 660 regular-length configuration is a common choice for job shops and production environments handling steel, alloy steel, cast iron, and similar materials where powdered metal tooling is the cost-effective alternative to solid carbide. The centercutting geometry allows the tool to plunge directly into the workpiece, giving machinists flexibility when programming pocketing or plunge-entry operations. The uncoated finish suits applications where coolant or cutting oil is used consistently to manage heat.

Key Features

• Powdered metal construction for consistent hardness and extended tool life in demanding cuts
• 3 flutes with a 50-degree helix angle for efficient chip evacuation and reduced cutting forces
• Centercutting design enables direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute for standard spindle rotation
• Uncoated — compatible with flooded coolant or cutting oil application
• Series 660 regular-length geometry balances rigidity and reach for typical milling depths

Compatibility

Designed as an OEM-style replacement or direct substitute for 0.625-inch shank square end mill applications in standard ER collet chucks, Weldon-style holders, and end mill holders rated for that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with milling tool setup procedures. Ensure the spindle is fully powered down and locked out before seating or removing the end mill from its holder. Verify runout with a dial indicator after tightening to the holder manufacturer's torque specification. Inspect the cutting edges visually before each use and replace the tool at the first sign of chipping or excessive wear to prevent workpiece damage or holder damage.
