43/64 Drill Bit - R W THOMPSON INC

The R W THOMPSON INC KK12-43/64 Drill Bit is designed for professional technicians and mechanics who demand precise hole creation and reliable performance in rigorous automotive and industrial settings. This 43/64 inch drill bit provides consistent accuracy across a range of materials, crucial for critical repair and fabrication tasks.

Key Features

• Precision Fractional Size: Engineered to an exact 43/64 inch (0.6719 decimal equivalent) diameter, vital for applications requiring precise hole dimensions and optimal component fitment.
• High-Speed Steel (HSS) Construction: Manufactured from robust HSS, this drill bit offers superior hardness, strength, and heat resistance, contributing to extended tool life in demanding drilling conditions.
• Self-Centering 135° Split Point: Facilitates rapid penetration and precise starting without the need for a pilot hole or center punch, effectively reducing bit walking on challenging workpieces such as engine blocks or machinery components.
• Reduced Shank with 3 Flats: Features a reduced shank designed to fit securely into standard 1/2-inch drill chucks, with a three-flat design ensuring a positive, non-slip grip during high-torque operations.
• Optimized Flute Design: Carefully engineered flutes efficiently evacuate chips and debris, maintaining a clean cutting edge and minimizing heat buildup for consistent performance and prolonged bit durability.

Applications

This versatile drill bit is an essential tool for a broad spectrum of professional applications. It effectively drills through various metals, including mild steel, cast iron, stainless steel, and high-tensile alloys commonly encountered in automotive repair, heavy equipment maintenance, and industrial fabrication. Specific uses include drilling hubs or axle flanges for wheel studs. It is also a reliable choice for heavy-duty drilling tasks across manufacturing, construction, and plant maintenance. Furthermore, it delivers clean and precise holes in diverse wood types, from softwoods to hardwoods, and can drill through various plastic materials without cracking or excessive melting, ensuring clean egress holes for custom work and repairs.
