Black Steel UNC-M16 Core Bit Adapter

A compact, purpose-built adapter engineered to bridge the thread mismatch between legacy 1-1/4"-7 UNC diamond core bits and M16-compatible drilling machines. Constructed from solid steel with a durable black finish, it maintains structural rigidity under high rotational force and thermal load. Its physical dimensions follow standard industrial tolerances (±1–3 cm), and colour consistency may vary slightly depending on ambient lighting—reflecting actual production batch variation rather than quality inconsistency. Designed exclusively for mechanical thread adaptation; no additional components or accessories included.
