KnKut 13 Piece HD Hex Shank M35 Cobalt Jobber Length Drill B - KnKut

The KnKut 13KK35 13 Piece HD Hex Shank M35 Cobalt Jobber Length Drill Bit Set is engineered to meet the rigorous demands of professional automotive and industrial applications. This professional-grade set delivers exceptional durability and consistent cutting performance, particularly when tackling high-tensile materials and abrasive alloys common in heavy-duty environments.

Key Features

• M35 Cobalt Steel Construction: Formulated with 5% cobalt, these drill bits maintain their hardness and cutting edge at elevated temperatures, allowing for efficient drilling through tough materials such as stainless steel, cast iron, and other hard metals without premature dulling.
• Heavy-Duty Hex Shank: The robust hex shank design provides a secure, non-slip grip in standard drill chucks. This maximizes torque transfer and prevents slippage during intensive drilling operations, especially with bits 3/16" and larger.
• 135° Split Point Tip: This self-centering tip ensures immediate, precise starts on contact, eliminating bit walking and the need for pre-drilling or center punching, even on curved or uneven surfaces.
• Jobber Length Design: Optimized for a balance of reach and rigidity, these jobber length bits are suitable for general-purpose drilling across various applications, offering stability and reducing breakage potential.
• Made in USA: Manufactured in the United States, adhering to stringent quality standards to ensure reliable performance and consistent results for professional users.

Applications

This versatile drill bit set is an indispensable tool for professional mechanics, fabricators, and maintenance technicians. It excels in critical tasks such as efficiently drilling out broken bolts, studs, and seized fasteners from challenging areas like engine blocks, exhaust manifolds, and braking systems. The set's robust construction also makes it highly suitable for general metalworking, fabrication tasks, and any situation requiring precise and efficient drilling in hard materials including stainless steel, Inconel, and titanium.
