Osg 484-3752 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The OSG 484-3752 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 3/8-inch cutting diameter with a 1.5-inch length of cut and a 6-inch overall length. The 4-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. Built from micrograin solid carbide, this end mill delivers the rigidity and wear resistance required for demanding cuts in ferrous and non-ferrous materials. The centercutting geometry allows for plunge milling in addition to peripheral and slot milling. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is suited for slotting, profiling, and contouring operations on CNC machining centers and manual mills. The uncoated micrograin carbide construction makes it a versatile choice across a range of work materials where a coating-specific substrate is not required. The 3/8-inch shank diameter fits standard ER collets and end mill holders commonly found in both vertical and horizontal machining setups. It is part of the OSG Series 484 lineup, which targets general-purpose solid carbide milling with consistent ground geometry.

Key Features

• Solid micrograin carbide construction for high rigidity and extended tool life
• 4-flute, right-hand cut and right-hand spiral flute geometry
• 30-degree helix angle for efficient chip flow and reduced cutting forces
• Centercutting design enables plunge, slot, and peripheral milling
• Uncoated finish suitable for general-purpose milling across multiple materials
• Single-end configuration with 3/8-inch shank for broad holder compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 3/8-inch end mill holders and ER collet chucks used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout specifications. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill from the collet or end mill holder. Confirm proper seating depth and holder torque per the toolholder manufacturer specification before initiating a cut. Inspect the cutting edges for chips or wear before each use and replace the tool when edge condition degrades to avoid workpiece damage or tool breakage.
