HSS Cobalt Drill Steptip 4.8mm
Bordo 4.80mm Metric Cobalt Tough HSS-Co5 Step Tip Drill – Extreme Performance Series
The Bordo 4.80mm Step Tip Drill is engineered for fast, precise drilling in high-strength materials. Made from high-speed steel with 5% cobalt (HSS-Co5), this bit delivers exceptional heat resistance, wear durability, and cutting performance—especially in stainless steel, high-tensile steels, and other tough metals.
Its step tip design eliminates the need for a pilot hole, allowing for quick starts, minimal walking, and accurate hole positioning across ferrous and non-ferrous metals as well as all types of timber.
Outfitted with a 1/4" hex shank, this drill bit is fully compatible with impact drivers, quick-change systems, and standard drill chucks, offering convenience and secure engagement on the job.
Finished in bronze (gold oxide), the bit undergoes a low-temperature tempering process used to identify cobalt-grade tools and provide a clear indication of wear over time.
Key Features:
4.80mm Step Tip: Enables fast starts and eliminates the need for pilot drilling.
HSS-Co5 Cobalt Steel: Delivers outstanding performance and longevity under heat and pressure.
1/4" Hex Shank: Perfect for impact drivers and quick-change adaptors.
