15 Piece Cobalt RED HELIX Drill Bit Kit -

The 15 Piece Cobalt RED HELIX Drill Bit Kit, model 48-89-2331, provides professional technicians and fabricators with a durable drilling solution for demanding applications. Engineered with a cobalt alloy construction and an advanced RED HELIX flute geometry, these bits deliver extended life and consistent performance in tough materials like stainless, cast, and structural steels, where standard high-speed steel bits typically falter.

Key Features

• Cobalt Alloy Construction: Offers exceptional heat resistance and hardness, ensuring prolonged bit life and reliable cutting through abrasive and high-strength metals such as stainless steel, cast iron, and hardened alloys.
• RED HELIX Flute Design: Features a Variable Helix™ flute that efficiently removes chips, minimizing heat buildup and maintaining continuous cutting edge engagement during deep or repetitive drilling operations.
• Precision Ground 135° Split Point Tips: Engineered to provide a precision start and prevent bit walking, allowing for accurate hole placement on challenging surfaces, including uneven, painted, or curved materials.
• Professional-Grade Durability: Built for rigorous daily use in professional automotive and industrial settings, these bits maintain cutting integrity under heavy loads in both cordless drill drivers and drill presses.
• Comprehensive 15-Piece Set: Includes a practical range of common fractional sizes to cover diverse general repair, upfit, and fabrication tasks, from creating pilot holes for fasteners to larger diameter drilling in plates and frames.

Applications

This 48-89-2331 kit is an essential tool for professional automotive, truck, and industrial shops. It excels in tasks involving light-duty pickups, heavy-duty trucks, trailers, and various equipment, facilitating the drilling of fastener and repair holes in chassis components, frames, crossmembers, suspension brackets, exhaust flanges, and body or bed mounts. Fabrication and welding professionals will find these bits indispensable for working with stainless steel, structural steel, and other abrasive alloys, where their robust design significantly extends bit life compared to conventional high-speed steel alternatives.
