AT Screw Machine Length Drills

AT screw machine length drills—often called stub length drill bits—are shorter-than-jobber drills designed for more rigid, controlled drilling. Because of their reduced length, screw machine drills can help minimize deflection and improve accuracy in many setups (application dependent), making them a popular choice for machining, fabrication, and production work where stability matters more than extra reach.
