The Dormer H851 HSS 12 drill exchange holder with internal cooling is a highly developed tool designed for precise drilling in various materials. With a cylindrical shank and flange, this drill body provides a reliable connection to exchangeable heads, enabling efficient machining. The internal cooling ensures that the temperature remains controlled during the drilling process, which extends the tool's lifespan and improves machining quality. The drill exchange holder is suitable for use in demanding applications and meets the high standards of the industry. With an overall length of 287.2 mm and a cutting length of 216 mm, it is ideal for 12xD drilling. The use of HSS (high-speed steel) ensures high wear resistance and excellent cutting performance.

• Suitable for 12xD drilling with HYDRA P, M, and K exchangeable heads
• Cylindrical shank with flange for stable connection
• Internal cooling for temperature control during the drilling process
• Made from high-speed steel (HSS) for high wear resistance
• Surface treatment with bright nickel plating for additional protection.
