Bordo 11.50mm Metric Cobalt Tough HSS-Co5 Step Tip Drill – Extreme Performance Series

The Bordo 11.50mm Step Tip Drill is built for rapid, accurate drilling in the most challenging materials. Constructed from premium high-speed steel with 5% cobalt (HSS-Co5), this bit offers outstanding hardness, heat resistance, and durability—ideal for stainless steel, high-tensile alloys, and other tough metals.

Its step tip geometry allows for fast starts and eliminates the need for a pilot hole, reducing walking and ensuring clean, precise drilling across both metal and timber. This makes it especially effective in applications such as sheet metal fabrication, pipework, electrical enclosures, and hardwoods.

Fitted with a 1/4" hex shank, the drill is ready for use with impact drivers, quick-change systems, and standard drill chucks, ensuring compatibility and fast bit swaps in the workshop or on-site.

The gold oxide (bronze) finish provides visual wear indication and is used to identify cobalt tooling — a hallmark of high-performance, professional-grade bits.

Key Features:

  • 11.50mm Step Tip: No pilot hole required; fast starts and reduced walking.

  • HSS-Co5 Construction: High cobalt content ensures superior performance in heat and hard material.

  • 1/4" Hex Shank: Quick-change compatible for efficient workflow on-site or in-shop.

  • Gold Oxide Finish: Identifies cobalt tools and helps detect wear.

  • Multi-Material Use: Drills cleanly through stainless steel, mild steel, aluminium, copper, brass, and timber.

For serious trades and industry professionals, the Bordo 11.50mm Cobalt Tough Step Tip Drill is a powerful, reliable choice when performance and speed matter.
