Osg 70201116 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The OSG 70201116 is a 2-flute solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 2-1/2 inch overall length with a 1/4 inch shank diameter. The tool is ground from micrograin carbide stock and finished with a diamond coating, which improves surface finish and extends tool life in ferrous and non-ferrous cutting. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduce cutting forces during slotting, profiling, and peripheral milling operations.

This end mill is suited for use in CNC machining centers and manual mills where tight tolerances and fine surface finishes are required. The stub-length configuration provides added rigidity, making it appropriate for shallow-to-medium-depth cuts in steel, aluminum, and similar machinable materials. It is a single-end tool with a right-hand cut and right-hand flute direction, consistent with standard spindle configurations on most vertical machining centers. The centercutting capability allows plunge entry without a pre-drilled pilot hole.

Key Features

• Micrograin solid carbide construction for wear resistance and dimensional stability
• Diamond finish coating for improved surface finish and extended tool life
• 30-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design permits direct plunge entry
• Right-hand cut and right-hand flute for standard spindle compatibility
• Stub length for increased rigidity in precision milling applications

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems accepting 1/4 inch shank tooling on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended insertion depth in the holder to minimize runout and prevent tool pull-out under cutting loads. Verify tool projection and runout with a dial indicator before beginning a new operation.
