Versatile tool holder for stand drills, lathes, CNC machines and milling machines - Expanded compatibility: ideal for stand drills, lathes, CNC machines and milling machines to handle turning stock with a single chuck setup. - Quick tool changes: tool-free opening and closing of the chuck for fast, hassle-free tool swaps. Suitable for both clockwise and anti-clockwise rotation. - Easy mounting and reliable fit: Mortise pin B16 to MK2 attaches without tools. Note: the ground cone surface must not be degreased to avoid welding the connection. - Clear specifications: clamping range 1-16 mm; tool holder with Morse taper MK2; drill chuck mounting cone B16. Usage scenarios - In a workshop, quickly switch between drilling and light milling operations without removing and reloading tools, reducing downtime. - On a CNC or milling machine, hold drills or end mills within 1-16 mm shank range for efficient, versatile machining. - On a lathe, use the MK2 Morse taper and B16 mounting cone to clamp small-diameter tooling for turning stock with minimal setup.
