51 #SCREW MACHINE - KnKut

The KnKut KK7-51 #51 Screw Machine Length Drill Bit is engineered for professional technicians and mechanics requiring exceptional precision and durability in demanding drilling applications. This stub-length drill bit, equivalent to a 0.0670-inch diameter, offers superior rigidity, minimizing deflection and breakage when working with tough materials or in confined spaces. Its robust construction ensures consistent performance and extended tool life in rigorous automotive and industrial environments.

Key Features

• Premium High-Speed Steel Construction: Manufactured from high-grade Hi-Molybdenum high-speed steel with a high vanadium content for enhanced strength and wear resistance.
• Salt Nitride Treated: KnKut's salt nitride treatment hardens the tool's surface, enabling it to drill effectively through challenging materials like stainless steel and titanium alloy.
• 135° Split Point Tip: Features a 135° split point tip that allows for self-centering, eliminating the need for a pilot hole or center punch, and reducing "walking" on the workpiece.
• Optimal Rigidity: The shorter flute and overall length compared to standard jobber drills significantly increase rigidity, improving accuracy and reducing the risk of breakage.
• Gold Surface Treatment: Provides maximum lubricity, reducing friction and heat buildup during drilling, which further extends tool life.
• Made in USA: Manufactured in the USA, ensuring consistent quality and professional-grade performance.

Applications

The KnKut KK7-51 #51 Screw Machine Length Drill Bit is an essential tool for a wide range of professional applications. It excels in precision drilling tasks where space is limited, such as in engine compartments, machinery assemblies, or intricate fabrication work. This drill bit is particularly effective for creating precise holes in harder materials like stainless steel, cast iron, and various alloys commonly found in automotive repair, industrial maintenance, and manufacturing. Its inherent rigidity makes it suitable for use in drill presses, lathes, milling machines, and automatic screw machines where stability and accuracy are paramount.
