Overview

Meet the Drill Hulk 13/64-inch cobalt drill bits, a set designed to handle demanding metalworking tasks with steadiness and precision. This 12-piece pack blends sturdy construction with practical geometry, making it a go-to choice for projects that involve hard metals and stainless steel. The result is a tool kit that offers a resilient cutting edge, dependable starts, and organized storage, all in one compact package.

Key Features and Benefits

  • Jobber-length design: 13/64-inch cutting diameter, 2-7/16-inch flute length, and 3-5/8-inch overall length provide balanced rigidity and smooth entry into metal.
  • 5% cobalt-infused HSS: Built from cobalt-steel alloy to improve red hardness and heat resistance, supporting durable performance in tough materials.
  • Sharpening versatility: The cobalt alloy maintains a uniform hardness, allowing the edges to be sharpened repeatedly without compromising cutting geometry.
  • Versatile application: Optimized for drilling in hard metals, including stainless steel, with reliable starts and clean holes.
  • Complete pack: Includes 12 pieces with a sturdy case for easy organization and quick selection during work sessions.

Performance in Real-Life Scenarios

These bits are designed to perform consistently as you move from one metal to another. Expect crisp pilot holes, steady chip evacuation, and a controlled cutting action that helps reduce wandering and break-in. The combination of cobalt reinforcement and jobber-length geometry is well-suited for automotive, machinery, and fabrication tasks where stainless steel or other hard metals are involved.

Usage Tips and Care

  • Use with appropriate cutting speeds and steady feed pressure to minimize heat buildup.
  • Keep edges sharp and occasionally relie on a light lubrication to extend edge life.
  • Secure workpieces firmly or use a drill press for accurate, perpendicular holes.
  • Store in the provided case to prevent edge nicks and keep the set organized.

What You Get

  • 12 high-performance cobalt drill bits with a robust case
