The Dormer A553 spiral drill is a high-performance tool specifically designed for precise drilling in various materials. With a nominal diameter of 8.5 mm and a robust HSS-E (High-Speed Steel) construction, this drill offers excellent performance and durability. The profile-ground quality ensures optimal cutting ability, while the TiAlN coating (Titanium-Aluminum-Nitride) reduces friction and extends the tool's lifespan. The drill is equipped with cooling channels that allow for effective cooling during the drilling process, which is particularly beneficial for deep drilling applications. With a drilling depth of up to 5xD, this spiral drill is ideal for use in steel, stainless steel, cast iron, and non-ferrous metals. The cutting direction is right-handed, ensuring easy handling and precise results.
