Osg 86301609 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The OSG 86301609 is a solid carbide square end mill designed for high-performance milling operations in metalworking and machining applications. With a 0.75-inch mill diameter and a 2.25-inch length of cut, this single-end tool delivers precise material removal across a wide range of workpiece materials. The diamond-like carbon (DLC) finish reduces friction and extends tool life in abrasive cutting conditions. A 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This end mill is installed and operated by machinists and CNC programmers working in production shops, tool rooms, and job shops.

This end mill is suited for slotting, profiling, and peripheral milling operations on ferrous and non-ferrous materials. The 3-flute geometry balances chip evacuation with edge strength, making it effective in both roughing and semi-finishing passes. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling on vertical and horizontal machining centers. The 0.75-inch shank diameter and 5-inch overall length accommodate standard ER and side-lock toolholders found on most CNC machining platforms.

Key Features

• 0.75-inch mill diameter with 2.25-inch length of cut for deep slotting and profiling
• Solid carbide construction provides rigidity and wear resistance over high-speed tool steel alternatives
• DLC finish reduces friction and improves tool life in dry and semi-dry cutting conditions
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting capability allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute configuration compatible with standard CNC spindle rotation

Compatibility

Designed as a standard 0.75-inch shank square end mill compatible with ER collet chucks, side-lock holders, and hydraulic toolholders sized for 0.75-inch shank tooling on CNC vertical and horizontal machining centers.

Installation Notes

This tool is installed and operated by qualified machinists and CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before loading or removing the end mill from the toolholder. Verify toolholder runout is within acceptable limits before starting a cut, as excessive runout accelerates edge wear on carbide tools. Follow the machine manufacturer and tooling manufacturer guidelines for speed, feed, and depth-of-cut parameters appropriate to the workpiece material.
