LETTER I SCREW MACHINE - KnKut

The KnKut KK7-I LETTER I SCREW MACHINE is a professional-grade, short stubby length drill bit designed for demanding automotive and industrial applications. Engineered for superior rigidity and precision, this Made in USA tool minimizes deflection and breakage, providing reliable performance in challenging drilling tasks, especially within confined spaces.

Key Features

• Premium HSS Construction: Manufactured from high-grade Molybdenum High-Speed Steel (HSS) with high Vanadium content, ensuring exceptional hardness and durability for extended tool life.
• Enhanced Drilling Capability: Specifically designed to drill tough materials such as stainless steel and titanium alloy with efficiency and precision.
• 135° Split Point Tip: Features a self-centering 135° split point that starts on contact, eliminating bit "walking" and often negating the need for a center punch or pilot hole.
• Stubby Length Design: The screw machine (short stubby) length provides increased rigidity and reduced flute length, making it ideal for robust drilling and use in right-angle drills or tight access areas.
• Gold Surface Treatment: Gold surface-treated for maximum lubricity, which reduces friction and heat buildup during operation, contributing to a cleaner cut and longer bit life.
• Letter I Size: Corresponds to a decimal equivalent of 0.2720 inches, offering a specific diameter for accurate hole creation.

Applications

The KnKut KK7-I is an indispensable tool for professional technicians and mechanics working across various automotive and industrial sectors. Its robust design and material composition make it suitable for drilling into hard-to-machine metals in engine compartments, chassis, and machinery assemblies. It excels in situations requiring precision drilling in restricted areas, pilot hole creation for threading, or addressing general repair and fabrication needs where conventional jobber-length bits may lack the necessary rigidity or maneuverability.
