1/2 X 6 In. Cobalt High-speed Drill Bit

Presenting the ½‑inch × 6‑inch Cobalt‑Enhanced High‑Speed Drill Bit, a precision‑engineered cutting instrument built for demanding metalworking tasks. Constructed from premium high‑speed steel alloyed with cobalt, this bit delivers exceptional rigidity and wear resistance. Its compact ½‑inch shank fits most standard rotary tools while the 6‑inch length provides deep‑reach capability. Designed for fast, clean entry, it reduces operator fatigue and improves overall productivity.

Why it matters: The cobalt infusion raises the thermal tolerance of the steel, allowing you to drill through heat‑treated alloys without losing edge sharpness. This means fewer bit changes, smoother holes, and a more reliable workflow when tackling stainless steel, chrome‑moly, or titanium components.

• Cobalt‑Infused High‑Speed Steel: Combines the hardness of HSS with 8% cobalt for superior heat resistance and prolonged tool life.
• 135° Split‑Point Geometry: Provides rapid self‑centering and eliminates wandering, delivering accurate starts on tough surfaces.
• Quad‑Edge Cutting Profile: Four precisely ground cutting edges slice material efficiently, reducing thrust force and extending bit lifespan.
• Exceptional Heat Deflection: Maintains cutting efficiency at temperatures exceeding 1000°F, ideal for continuous drilling of hardened metals.
• Optimized for Tough Alloys: Perfect for stainless steel, chrome‑moly, manganese steel, titanium, armor plate, and other high‑strength applications.

Ready for the toughest jobs: Whether you’re fabricating aerospace components, repairing heavy‑duty equipment, or machining custom fixtures, this cobalt‑enhanced drill bit offers the reliability and performance professionals demand. Experience quicker penetration, cleaner holes, and unmatched durability—making it the go‑to choice for any hard‑metal drilling challenge.
