Drill Hulk 11/64-Inch Cobalt Drill Bits – Jobber Length, 12-Piece Set for Hard Metals & Stainless Steel

Drill Hulk 11/64-Inch Cobalt Drill Bits — Precision for Hard Metals

Meet a cobalt-infused twist drill set designed to handle demanding metalworking tasks with steadiness and control. The 11/64-inch cutting diameter, 2-1/8-inch flute length, and 3-1/4-inch overall length provide a balanced bite and consistent hole size, while a 135-degree split point helps start holes cleanly in challenging materials.

Superior construction for hotter work

• JOBBER LENGTH: 11/64-inch cutting diameter, 2-1/8-inch flute length, 3-1/4-inch overall length, 135 degree split point, straight shank
• MADE FROM HIGH-SPEED STEEL AND 5% COBALT: boosted heat resistance and red hardness for better performance on hard metals
• CAN BE REPEATEDLY SHARPENED: cobalt bit hardness remains uniform throughout, enabling periodic sharpening and longer use
• APPLICATION: designed for drilling in hard metal, including stainless steel

What’s in the set and how it helps

• INCLUDE: 12 pieces of 11/64-inch cobalt drill bits with case for organized transport
• CASE-READY STORAGE: keeps bits protected and accessible between jobs
• RELIABLE HOLE QUALITY: robust edge geometry supports accurate starts and steady drilling under load

These cobalt-enhanced bits are suited for workshop use, fabrication tasks, and DIY metal projects where stainless steel or other hard metals are part of the workflow. The blend of cobalt and high-speed steel aims to offer a blend of edge retention and toughness, while the included case helps you keep the set organized. As with any drilling task, results depend on technique and material, but the composition and design choices here suggest versatility for a range of metalworking scenarios.
