Osg 484-2501 Square End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The OSG 484-2501 is a solid carbide square end mill designed for precision material removal in milling operations. It features a 1/4 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length with a 1/4 inch shank diameter. The four-flute, right-hand spiral design at a 30-degree helix angle promotes efficient chip evacuation and a stable cut. Micrograin carbide construction delivers edge hardness and wear resistance suited to demanding cutting conditions. This is a centercutting tool, allowing plunge entry directly into the workpiece. It arrives uncoated and ready for use on compatible CNC or manual milling equipment.

The 484-2501 is suited for general-purpose milling in ferrous and non-ferrous materials where a standard 1/4 inch square end profile is required. Typical applications include profiling, slotting, and contouring operations in job shop, production, and toolroom environments. The Series 484 designation places it within OSG's standard solid carbide end mill line for broad material compatibility. It is a single-end tool with right-hand fluting and no chipbreaker, making it straightforward to apply across a wide range of milling setups.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• Four flutes with right-hand spiral at 30-degree helix angle for efficient chip flow
• Centercutting geometry allows direct plunge milling without pre-drilling
• Uncoated finish suitable for a wide range of standard milling applications
• 1/4 inch shank matches common collet and end mill holder sizes
• No chipbreaker or variable helix — consistent, predictable cut geometry

Compatibility

Designed as a standard OEM-style solid carbide square end mill for use in 1/4 inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the collet or end mill holder to the recommended grip depth before tightening. Verify spindle speed and feed rate against the tool manufacturer's cutting data for the workpiece material before starting the cut. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
