The standard head is an accessory of the Challenge MS-5 Multi-Spindle Paper Drill with 3 Standard Heads. It is a three-spindle paper drilling head designed for typical office and industrial paper-drilling tasks. Each spindle in the standard head holds a drill bit, and allows the machine to drill three holes simultaneously in a stack of paper or light cardstock. The standard head is metallic and durable, built to ensure precise hole alignment and consistent spacing across all three spindles. It is also interchangeable, so users can replace or adjust the spindles to accommodate different drill diameters or patterns, offering flexibility for various paper sizes and binding requirements.
