Bordo 4.20mm Metric Cobalt Tough HSS-Co5 Step Tip Drill – Extreme Performance Series

The Bordo 4.20mm Step Tip Drill is built for high-speed, precision drilling across a wide range of tough materials. Made from high-speed steel with 5% cobalt (HSS-Co5), it offers superior hardness, heat resistance, and extended tool life—ideal for stainless steel, high-tensile steels, and other hard-to-drill metals.

Its step tip design eliminates the need for a pilot hole, enabling rapid starts, reduced walking, and clean, accurate holes in ferrous and non-ferrous metals, as well as all types of timber.

Featuring a 1/4" hex shank, this drill is impact driver-compatible and suits quick-change systems and standard drill chucks—perfect for fast, efficient bit swaps on-site or in the workshop.

The bronze (gold oxide) surface finish not only identifies the bit as a cobalt-grade tool but also provides a clear visual indication of wear during use.

Key Features:

  • 4.20mm Step Tip: No pilot hole required; drills fast and true.

  • HSS-Co5 Cobalt Steel: Exceptional heat resistance and durability.

  • 1/4" Hex Shank: Compatible with quick-change adaptors and impact drivers.

  • Gold Oxide Finish: Cobalt tool identification and wear indication.

  • Multi-Material Performance: Drills stainless steel, mild steel, aluminium, brass, copper, and timber with ease.

Precision-made and trade-tough, the Bordo 4.20mm Step Tip Cobalt Drill is the reliable choice for professionals who demand speed and durability in every hole.
