The HSS drill with a left-hand cutting design and a diameter of 4.0 mm is a precise tool specifically designed for machining metal, particularly steel. This spiral drill is characterized by its high quality, ensured by the use of HSS steel (high-speed steel). The titanium nitride surface treatment increases the drill's lifespan and enhances its cutting properties, leading to more efficient machining. With a compact working length of 0.4 cm, this drill is ideal for precise applications where accuracy and control are required. The left-hand cutting drill is especially useful in specialized applications where a left-handed rotation is necessary, providing excellent performance in metalworking.

• High-quality HSS steel for durability and efficiency
• Titanium nitride surface treatment for improved cutting properties
• Specifically designed for left-handed applications
• Suitable for machining steel and other metals.
