Osg 20240100 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The OSG 20240100 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 1/4 inch mill diameter, 1/4 inch length of cut, and 4 inch overall length, this tool is built for extended-reach applications where standard-length end mills cannot access the work area. The 30-degree helix angle and right-hand spiral flutes promote efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the rigidity and wear resistance required for consistent performance in ferrous and non-ferrous materials. This end mill is installed and used by machinists and CNC operators in production and job-shop settings.

The OSG 20240100 is suited for slotting, profiling, and peripheral milling where a long-reach, small-diameter tool is required. The extended reach length of approximately 2-1/8 inches allows access to deep pockets and stepped features that shorter tools cannot reach. The bright, uncoated finish makes it a straightforward choice for general-purpose applications where coating is not required by the material or process. It is a single-end tool used in vertical machining centers, CNC mills, and manual knee mills with a 1/4 inch collet or end mill holder.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• 1/4 inch diameter with 1/4 inch length of cut and 4 inch overall length

Compatibility

Designed for use in 1/4 inch collet chucks, ER collets, or end mill holders on vertical machining centers and CNC milling machines. Part of the OSG Series 2024 long-reach end mill family.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank fully in a 1/4 inch collet or end mill holder to the recommended gauge length before tightening. Verify spindle runout with a test indicator before cutting to protect the tool and workpiece. Do not exceed the tool manufacturer's recommended feed and speed parameters for the material being cut.
