KnKut 3/16 Left Hand High-Speed Stainless Steel Drill Bit - R W THOMPSON INC

The KnKut 3/16 Left Hand High-Speed Stainless Steel Drill Bit (Model KK6-3/16) from R W THOMPSON INC is engineered for professional technicians and mechanics who demand reliable performance in fastener extraction and challenging drilling applications. This robust, USA-made drill bit is specifically designed for counter-clockwise rotation, enabling efficient work with tough materials such as stainless steel and other high-strength alloys.

Key Features

• Left-Hand Spiral Design: Specifically engineered for counter-clockwise rotation, this drill bit is ideal for efficiently loosening and extracting broken fasteners like bolts, screws, and studs, often eliminating the need for separate extractors. Its reverse cutting action can back out a fastener during drilling.
• Premium HSS Construction: Manufactured from high-grade Molybdenum high-speed steel with a high vanadium content, it provides enhanced durability, heat resistance, and extended tool life under rigorous operating conditions.
• Salt Nitride Treatment: A deep-penetrating salt nitride treatment significantly increases the tool's surface hardness, wear resistance, and fatigue resistance. This allows for effective drilling through robust materials, including various grades of stainless steel and titanium alloys.
• 135° Split Point: The 135-degree split point tip ensures accurate starts on contact, minimizes "walking" or slipping, and often eliminates the necessity for a center punch or pilot hole, resulting in precise, round holes, particularly in hard metals and on curved surfaces.
• Gold Surface Treatment: The body and clearance feature a gold surface treatment for maximum lubricity, effectively reducing friction and heat buildup during drilling, which prolongs tool life and offers corrosion resistance.

Applications

This professional-grade drill bit is designed for a range of industrial and automotive tasks. It excels in fastener extraction, allowing technicians to efficiently remove damaged or corroded bolts and screws from critical components such as engine blocks, chassis, and various machinery. The left-hand rotation is also valuable in reverse drilling scenarios where counter-clockwise action is required. Additionally, its robust HSS construction and specialized treatments make it well-suited for general metalworking tasks, including drilling through stainless steel, high-tensile steel, and other hard metals in fabrication and repair environments.
