50 #SCREW MACHINE - KnKut

The KnKut KK7-50 #50 Screw Machine Length Drill Bit is engineered for professional automotive and industrial applications requiring precision and durability in demanding conditions. This Made-in-USA drill bit is constructed from high-grade Molybdenum High-Speed Steel (HSS) with a high vanadium content, designed to withstand rigorous use in professional environments. Its robust construction ensures reliable performance and extended tool life, minimizing downtime for technicians and mechanics.

Key Features

• Optimized Rigidity: Featuring a shorter flute and overall length compared to standard jobber bits, this screw machine length drill bit offers enhanced rigidity to reduce deflection and breakage during tough drilling tasks.
• Advanced Material Composition: Manufactured from premium Molybdenum High-Speed Steel with high vanadium content, ensuring superior strength and wear resistance.
• Enhanced Hardness: KnKut's salt nitride treatment penetrates the tool's surface, providing exceptional hardness for drilling challenging materials such as stainless steel and titanium alloy.
• Precision Drilling: The 135° split point tip promotes self-centering and reduces bit walking, often eliminating the need for a center punch or pilot hole for accurate hole initiation.
• Improved Lubricity: A gold surface treatment on the bit maximizes lubricity, reducing friction and heat buildup during drilling, which further extends tool life.

Applications

The KnKut KK7-50 #50 Screw Machine Length Drill Bit is suitable for a wide range of professional applications, particularly where precision drilling and material toughness are critical. It excels in automotive repair for drilling into chassis components, exhaust systems, or engine blocks, and in industrial settings for fabricating and maintaining machinery. Its short, rigid design makes it ideal for working in confined spaces and for creating accurate holes in various metals, including hardened steel, sheet metal, and alloys.
