Osg 414-4375 Square End Mill 7/16 in 4 Flute Solid Carbide

Product Description

The OSG 414-4375 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in machining centers and CNC milling operations. Built from micrograin solid carbide, it delivers rigidity and edge retention well beyond high-speed steel alternatives. The 7/16 inch cutting diameter and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. At 0.2 pounds, this is a compact stub-length tool suited for applications where overhang must be minimized and surface finish is critical. It ships uncoated and is ready to run as-received or can be coated to spec by the end user.

The 414-4375 is used in precision machining environments where tight tolerances and consistent tool geometry are required. The stub-length configuration reduces deflection, making it well-suited for slotting, profiling, and face milling on hardened or tough workpiece materials. Machinists and tool-and-die professionals working on production runs or prototype work will find this tool reliable in both light and moderate chip-load applications where a square shoulder finish is required.

Key Features

• 7/16 inch cutting diameter with matching 7/16 inch shank diameter for direct collet or end mill holder fitment
• 4-flute configuration for improved surface finish and feed rate capability versus 2-flute designs
• 30-degree helix angle for balanced chip evacuation and cutting force distribution
• Micrograin solid carbide substrate for extended tool life and edge integrity
• Centercutting design allows plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute - standard rotation for conventional CNC spindles
• Uncoated finish - compatible with recoating services or direct use in appropriate material applications

Compatibility

Designed as a direct-fitment stub-length square end mill for standard 7/16 inch collets and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer's torque and runout specifications. Ensure the shank is fully seated in the collet or holder to the recommended engagement depth before securing. Verify spindle runout does not exceed the tolerance required for the application before beginning a cut. Do not exceed the tool's rated depth-of-cut or feed rate for the workpiece material.
