OSG 55° Helix Endmill Corner Radius - Centre Cutting Regular Length - 12mm x R1.5

The OSG 55° Helix Endmill with a corner radius is a versatile, centre-cutting tool designed for general machining tasks. This 12 mm diameter cutter features a 1.5 mm corner radius and a regular-length body, delivering stable, precise cuts across profiles, slots, and contours.

Engineers, machinists, and hobbyists will appreciate the 55-degree helix angle for efficient chip evacuation and lower cutting forces, which translate to smoother entry, less heat buildup, and reliable performance in a variety of materials. The corner radius enhances edge strength and helps produce uniform surface finishes, even on complex profiles.

• 55° Helix for Efficient Chip Evacuation: Sharp, angled flutes move chips away quickly, reducing heat and vibration for cleaner cuts and longer tool life.
• Corner Radius R1.5 for Smoother Edges: R1.5 softens entry and exit, improves surface finish on profiling work, and minimizes chatter in tight corners.
• Centre-Cutting Design for Versatile Machining: Capable of plunging, full-depth milling, profiling, and slotting with a single tool—reducing setup time and tool changes.

This endmill supports a consistent, high-quality workflow across a range of general machining applications. Its robust geometry and reliable performance help you achieve repeatable results, improve finish quality, and keep production moving smoothly from setup to part completion.
