Drill Hulk 1/8-Inch Cobalt Drill Bits M35 Jobber Length – Pack of 12 for Hard Metal & Stainless Steel

Designed for tough metals, ready for real-world projects

Meet the Drill Hulk 1/8-inch cobalt drill bits, a reliable set built to handle hard metals and stainless steel with steady, controlled performance. These bits blend high-speed steel with 5% cobalt to improve heat tolerance and edge retention, so you can work through demanding materials with more confidence. The jobber-length design—1/8-inch cutting diameter, 1-5/8-inch flute length, and 2-3/4-inch overall length—offers a balanced feel and favorable rigidity, helping you maintain a true path through metal without excessive wandering.

The 135-degree split point is engineered to begin cutting cleanly on contact, reducing walk and letting you start holes with minimal guide work. A straight shank ensures compatibility with common drill chucks, so you can drop them into your setup and drill with less fuss. This pack includes twelve 1/8-inch cobalt drill bits, neatly organized in a durable carry case for on-site tasks or workshop use.

Key specs that matter

• JOBBER LENGTH: 1/8-inch cutting diameter, 1-5/8-inch flute length, 2-3/4-inch overall length
• 135-degree split point for precise starts and reduced wandering
• Straight shank for broad chuck compatibility
• Includes: 12 pieces in a sturdy case

Materials and performance you can rely on

• Made from high-speed steel with 5% cobalt, which provides higher red hardness and heat tolerance compared to standard HSS bits
• Uniform hardness throughout the body allows repeated sharpening without compromising the cutting edge
• Optimized for hard metals and stainless steel, helping you tackle demanding drilling tasks with consistency

Real‑world use cases and practical tips

• Metalworking projects that involve stainless steel brackets, housings, or fittings
• Automotive or fabrication tasks where durable tools are needed to pierce hard alloys
• DIY and professional settings where portable, organized bit storage helps keep projects on track

Results depend on technique, material, and drilling parameters. You may notice cleaner entry holes, steadier starts, and longer tool life when you pair these bits with proper feeds, speeds, and lubrication. While not a guarantee, the cobalt blend and robust geometry offer a capable option for challenging metals.
