HY-PRO® CARB VGM Series

The HY-PRO® CARB VGM end mill is a series of variable geometry end mills for dynamic milling ideal in steel and stainless steel. With variable index and unique flute geometry, the OSG HY-PRO® CARB VGM series features unequal flute spacing which reduces vibration during machining by altering the timing of each flute engaging in the workpiece. In addition, a sharp rake angle, high helix and adjusted core diameter maintains excellent cutting edge sharpness and tool rigidity to promote smooth, stable cutting with low cutting force.
