Osg 484-1575 Square End Mill 0.1575 in 4 Flute Carbide

Product Description

The OSG 484-1575 is a solid carbide square end mill designed for precision milling operations in a wide range of metalworking and machining applications. With a 0.1575 inch (4.00 mm) mill diameter and a 1.2205 inch (31.00 mm) length of cut, this tool delivers consistent performance in finishing and light roughing passes. The 4-flute configuration combined with a 30-degree helix angle promotes smooth chip evacuation and reduces chatter at higher feed rates. Machined from micrograin carbide stock, it holds tight tolerances longer than standard carbide grades and is well suited for use on CNC machining centers and manual mills.

This end mill is appropriate for use in job shops, tool rooms, and production machining environments where small-diameter, high-precision work is required. It is centercutting, allowing plunge entry directly into the workpiece. The right-hand cut and right-hand spiral flute geometry make it compatible with standard spindle setups. It is sold individually and is intended for use by machinists and CNC operators working with ferrous and non-ferrous materials at conventional milling speeds.

Key Features

• 0.1575 inch (4.00 mm) mill diameter for small-feature and tight-tolerance work
• 1.2205 inch (31.00 mm) length of cut for adequate reach without excessive deflection
• 4-flute spiral design with 30-degree helix for improved surface finish and chip flow
• Centercutting geometry allows direct plunge milling without pilot drilling
• Micrograin solid carbide construction for extended tool life and edge retention
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines using 4.00 mm shank toolholders, collets, or equivalent ER-series chuck systems where a 4.00 mm shank diameter is specified.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Use a properly sized collet or end mill holder matching the 4.00 mm shank diameter to prevent runout and premature tool failure. Do not exceed the tool manufacturer recommended depth of cut or feed rate for the workpiece material being machined.
