What Is Billet Aluminum? CNC Machining Guide
The word billet gets thrown around like a quality badge: billet wheels, billet intake manifolds, billet phone cases, billet everything. Marketing has stretched the term so far that most buyers, and plenty of hobbyist machinists, cannot say precisely what it means. This guide fixes that. It defines billet against cast and forged stock, explains why machinists care, compares the two grades that dominate hobby and pro shops (6061 and 7075), and walks through the feeds and speeds basics for cutting billet aluminum on a mill or aluminum-capable CNC router.
