13 PC COBALT SET - Vermont American

The Vermont American 12687 13 PC COBALT SET is specifically engineered for professional technicians and mechanics who demand reliable performance in challenging drilling applications. This comprehensive 13-piece cobalt drill bit set offers common fractional sizes from 1/16" to 1/4" in 1/64" increments, providing consistent results in abrasive and high-strength materials found across automotive and industrial sectors.

Key Features

• Cobalt Alloy Construction: Manufactured with a robust cobalt alloy, these drill bits are designed to bore through tough materials such as stainless steel, cast iron, titanium, and other high-strength alloys, ensuring extended wear resistance.
• Superior Heat Resistance: The inherent properties of cobalt allow these bits to maintain cutting efficiency and prolong tool life, even under the high temperatures generated during continuous drilling in demanding conditions.
• Precision 135° Split Point: Each drill bit features a 135-degree split point tip, facilitating quick, accurate starts without requiring a center punch and effectively preventing "drill walking" on curved or uneven surfaces.
• Comprehensive Size Range: This 13-piece set includes fractional sizes from 1/16" to 1/4" in 1/64" increments, offering the versatility needed for a broad spectrum of professional drilling tasks.
• Professional-Grade Durability: Built to withstand the rigors of daily professional use, these cobalt drill bits ensure reliability and consistent performance over time, making them a cost-effective choice for industrial and automotive tools.

Applications

This professional-grade cobalt drill bit set is an essential tool for contractors, maintenance crews, and machine shops. It excels in automotive repair scenarios, such as drilling into stainless steel exhaust components, engine brackets, or chassis work where standard bits may fail. The set is also highly effective in industrial fabrication and general maintenance tasks involving hard metals, making it ideal for use in garages and workshops where consistent performance and precise material removal are critical. These cobalt drill bits are suitable for drilling high-alloyed steels, bearing steels, and both hot and cold-rolled steel.
