• Precision High-Speed Steel Construction: This 9Pcs boring bar set is made from high-speed steel, ensuring durability, heat resistance, and long service life during demanding CNC lathe operations. Each 12mm F1 type boring bar delivers consistent performance for accurate internal machining in metalworking projects.
• Complete Set with Varied Lengths and Depths: The boring bar set includes nine tools with different drilling depths and reach lengths, allowing you to tackle a wide range of hole sizes—from 7.9mm to 13mm—and workpiece configurations. This versatility makes the boring bar ideal for complex or multi-stage boring tasks.
• Designed for Machinists and DIY Enthusiasts: Whether you're a professional machinist or a hobbyist working on home workshop projects, this boring bar set supports precise internal turning on lathes. Its standardized 12mm diameter ensures easy installation and compatibility with common tool holders and machines.
• Durable and Reliable Material Quality: Crafted entirely from high-speed steel, each boring bar in this set maintains sharpness and structural integrity under high-speed rotation and heavy cutting loads. The material resists wear and deformation, providing reliable results across aluminum, steel, and other metals.
• Convenient Storage and Organization Included: The set comes with a compact storage base (approx. 72 x 55 x 30mm) that keeps all nine boring bars neatly organized and protected. This makes the boring bar set easy to transport, prevents loss, and ensures quick access during machining sessions.
