Osg 37420015 Square End Mill 0.4134 in 4 Flute Solid Carbide

Product Description

The OSG 37420015 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.4134-inch (10.5 mm) cutting diameter, a 1.3386-inch (34 mm) length of cut, and a 0.4724-inch (12 mm) shank diameter, this tool delivers consistent stock removal and tight tolerances. The 4-flute, 30-degree helix geometry promotes chip evacuation and surface finish quality. The WXL coating enhances wear resistance and extends tool life in demanding cutting conditions. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual milling machines where repeatable accuracy is required.

This end mill is suited for peripheral and slot milling applications in job shop, production, and toolroom environments. Its centercutting capability allows plunge entry without a pre-drilled hole, making it versatile across roughing and finishing passes. The 90 mm overall length and 12 mm shank diameter are common fits for standard end mill holders and collet chucks used in both vertical and horizontal machining centers.

Key Features

• Solid carbide micrograin substrate for rigidity and edge retention
• WXL coating for improved wear resistance in high-speed and dry cutting
• 4 flutes with 30-degree right-hand helix for efficient chip flow
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Single-end design with 0.4724-inch shank for secure tool holding

Compatibility

Designed as an OEM-style replacement and standard cutting tool for CNC machining centers and manual mills accepting a 0.4724-inch (12 mm) shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank to the minimum recommended engagement depth in the holder and torque the set screw or collet nut per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to prevent premature tool wear or breakage.
