Osg 20221700 Square End Mill 0.25 in 2 Flute Solid Carbide

Product Description

The OSG 20221700 is a solid carbide square end mill designed for precise milling operations in metal, composites, and engineering plastics. With a 0.25 inch cutting diameter and a 2-flute spiral configuration at a 30-degree helix angle, this end mill delivers efficient chip evacuation and clean square-shoulder cuts. The right-hand cut, right-hand flute geometry suits conventional and climb milling setups. At 0.5 pounds, it is sized for compact toolholders in CNC machining centers and manual knee mills. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, giving machinists added flexibility on the shop floor.

This end mill is well suited for light to moderate slotting, profiling, and pocketing operations in job shop and production environments. The regular-length body keeps overhang minimal, which reduces deflection on tighter tolerance features. The 0.75 inch length of cut handles standard depth passes in ferrous and non-ferrous materials. Machinists working in general-purpose CNC or manual milling applications will find the geometry appropriate for both roughing passes at conservative chip loads and finish passes on close-tolerance workpieces. This is a single-end, uncoated tool from the OSG Series 2022 line.

Key Features

• Solid carbide construction provides rigidity and heat resistance over high-speed steel alternatives
• 2-flute spiral design promotes chip clearance in slotting and full-width cuts
• 30-degree helix angle balances cutting force and surface finish quality
• Centercutting geometry permits direct plunge entry into workpiece material
• Right-hand cut and right-hand flute orientation compatible with standard spindle rotation
• Regular length body minimizes deflection for improved dimensional accuracy

Compatibility

Designed as an OEM-style replacement and standard tooling option for 0.25 inch collet chucks, end mill holders, and hydraulic toolholders used in CNC machining centers and manual milling machines requiring a 0.25 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Verify collet or holder bore cleanliness and confirm proper seating depth to the specified gauge line before tightening. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material being cut.
