Drill Hulk 7/32-Inch Cobalt Steel M35 Jobber Length Twist Drill Bits – 12-Piece Set

Drill Hulk 7/32-Inch Cobalt Drill Bits: Precision for Hard Metals

Meet a reliable partner for metalworking projects that demand durable, precise cutting. The Drill Hulk 7/32-inch cobalt drill bits are forged from high-speed steel with 5% cobalt, delivering improved red hardness and steadier performance when you push through hard metals like stainless steel. The 12-piece set comes in a sturdy case that keeps each bit neatly organized and easy to grab on a busy shop day.

Why cobalt matters in metal drilling

• Higher heat resistance: The cobalt blend stands up to higher temperatures that occur when drilling hard metals, helping maintain cutting efficiency.
• Uniform hardness: The cobalt is distributed throughout the bit for consistent performance, making sharpenings possible without compromising edge integrity.
• Better initial bite: The 135-degree split point quickly creates a guide hole, reducing walk and chatter as you start the cut.

Design details you’ll notice

• JOBBER LENGTH: 7/32-inch cutting diameter, 2-1/2-inch flute length, 3-3/4-inch overall length for a balanced reach in metalworking projects.
• 3-FLAT SHANK: A stable grip in your drill chuck helps minimize slipping and improves control.
• RESHARPENABLE: The material’s uniform hardness supports repeated sharpening, extending the bit’s usable life beyond typical HSS bits.

Real-world uses and expectations

These cobalt bits excel when drilling through hard metals and stainless steel, including automotive components, tool housings, and hardware fixtures. Expect cleaner hole edges, smoother cutting action, and reduced clogging as you work through stubborn alloys. While results vary with drill speed and feed rate, many users appreciate the combination of toughness, edge retention, and versatility across metal types.

What you get

• 12 pieces of 7/32-inch cobalt drill bits
• Case for organized storage and transport
