Osg 414-7500 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The OSG 414-7500 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 3/4 inch mill diameter, 1 inch length of cut, and 3 inch overall length, this stub-length tool offers rigidity in tight setups where deflection must be minimized. The four-flute, right-hand spiral design with a 30-degree helix angle provides efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and wear resistance needed for ferrous and non-ferrous materials. This tool is intended for use by machinists and tool-and-die professionals on CNC and manual milling equipment.

The 414-7500 fits standard 3/4 inch collets and tool holders commonly found in vertical mills, machining centers, and CNC routers. Its centercutting capability allows plunge milling in addition to conventional peripheral and slot milling. The stub overall length makes it well suited for face milling, contouring, and pocketing operations where a shorter tool-to-spindle distance improves stability and surface finish. This is a single-end, uncoated tool in the OSG Series 414 lineup.

Key Features

• 3/4 inch mill diameter with matching 3/4 inch shank for direct collet mounting
• Four right-hand spiral flutes with 30-degree helix angle for efficient chip flow
• Centercutting design allows plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate for durability in demanding cuts
• Stub overall length (3 inches) increases tool rigidity and reduces vibration
• Uncoated finish suitable for applications where coolant is used or coating is not required

Compatibility

Designed as a direct-fit replacement for standard 3/4 inch shank square end mill applications using ER collets, end mill holders, or Weldon-style tool holders on vertical machining centers and CNC mills.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered down and locked out before tool changes. Ensure the shank is fully seated in the collet or holder to the recommended engagement depth before torquing the retention nut or set screw. Inspect the cutting edges for chips or damage before each use. Follow the machine manufacturer's guidelines for spindle speed (RPM) and feed rate selection based on material and depth of cut.
