WildBossy M35 Cobalt Drill Bit Set 20PCS (1/16"-1/2") High Speed Steel for Hardened Metal

WildBossy M35 Cobalt Drill Bit Set — Precision for Tough Materials

Meet a robust kit designed to tackle harder metals with confidence. Crafted from M35 cobalt steel with additional molybdenum and cobalt, these bits form a hardened alloy that resists wear and heat. This combination can help you cut faster and extend the life of the tools compared with standard high speed steel. A titanium-like surface coating adds another layer of protection, helping shed heat and maintain edge integrity through longer drilling sessions.

Ideal for a range of project work, this 20-piece kit covers common hole sizes and includes a convenient index storage case for quick access and orderly organization. The set is suited for stainless steel, standard steel, cast iron, and even nonferrous metals, giving you options when a project shifts from metal to metal. It is not recommended for glass or ceramic materials, and applying proper speed, pressure, and heat control will help you get the most from each bit.

Key design advantages at a glance

• 135 degree split point reduces wandering and starts holes cleanly for a confident first cut.
• Ti surface coating paired with cobalt content enhances heat resistance and chip evacuation during tough jobs.
• 3-flat shank design provides a secure grip in the chuck and minimizes slip during use.
• Fully ground cutting edges support smooth chip movement and consistent cutting action from start to finish.

Real‑world use cases

In a shop or at home, you can rely on these bits for drilling into stainless steel, steel, and cast iron, as well as aluminum alloys when needed. They pair well with cordless and corded drills alike, provided you choose appropriate speed and feed rate to control heat buildup. The included index case keeps the bits organized between jobs, helping you locate the right size quickly.

• Safer, cleaner starts thanks to the split point design.
• Reduced wear in high-stress drilling tasks with cobalt alloy and Ti coating.

As with any tool, results will vary with material quality, lubrication, and operation technique. Use protective gear and follow recommended safety practices. This WildBossy kit is designed to expand your capabilities without promising guaranteed outcomes, offering a reliable set of possibilities for your projects.
