LETTER D SCREW MACHINE - KnKut

The KnKut KK7-D LETTER D SCREW MACHINE drill bit is engineered for professional technicians and mechanics who demand precision and durability in challenging drilling applications. This specialized screw machine length drill bit delivers exceptional rigidity and accuracy, making it an indispensable tool for consistent, high-quality results in automotive and industrial environments.

Key Features

• Premium HSS Construction: Manufactured from high-grade Molybdenum High-Speed Steel (HSS) with a high Vanadium content, ensuring superior hardness and wear resistance.
• Optimized for Tough Materials: Designed to effectively drill through a range of demanding materials, including stainless steel, titanium alloy, and other hardened metals, as well as wood and plastics.
• Letter D (.2460") Diameter: Precision-ground to a Letter D size, equivalent to .2460 inches, for accurate hole creation.
• Screw Machine Length: Its shorter, more rigid design minimizes deflection and breakage, providing enhanced stability and control for shallow hole drilling in high-performance equipment.
• 135° Split Point: Features a 135-degree split point that allows for self-centering, eliminating the need for a pilot hole or center punch and ensuring immediate, accurate penetration.
• Salt Nitride Treated: KnKut drills are often salt nitride treated, which penetrates the tool's surface to enhance hardness and extend tool life, especially when drilling tough materials.

Applications

The KnKut KK7-D LETTER D SCREW MACHINE is ideal for tasks requiring precise, rigid drilling. It is commonly used in screw machines, CNC equipment, and other setups where stability is paramount. Professional mechanics will find it effective for drilling out broken bolts, preparing holes for tapping in engine components, chassis work, and other intricate automotive repairs. Its robust construction also makes it suitable for various industrial maintenance and fabrication tasks, particularly when working with tough alloys where conventional drills may fail.
