BECOLLO 1/2-Inch Cobalt Drill Bit Set – M35 HSS, 3-Piece

BECOLLO 1/2 Inch Cobalt Drill Bit Set

Engineered for metalworking, the BECOLLO cobalt drill bit set pairs M35 high speed steel with 5 cobalt for superior wear and heat resistance. The three bits are designed to endure challenging holes in hard metals while maintaining precise starts that help you approach each task with confidence.

Why cobalt matters

The cobalt content strengthens the cutting edge, helping the bits stay sharper longer under high temperature drilling. This can translate to longer tool life and steady performance through multiple holes in tough materials.

• Wear resistance keeps edges sharper under heat
• Heat tolerance supports steady cutting when drilling hard metals

Built for speed and precision

The bits benefit from a fully ground surface that reduces friction and enables smoother entry. The 135 degree split point design improves cutting speed at the start and helps the bit stay centered on the mark, reducing wandering across the workpiece.

• Smoother surface reduces binding and speeds up drilling
• 135 degree split point facilitates self centering and initial bite

Versatility and practical details

Ideal for stainless steel and cast iron, the set also handles softer metals and general purpose tasks. The 1/2 inch size fits common drill chucks, minimizing the need for adapters. All three bits arrive in a compact plastic case for storage and transport, manufactured under ANSI B94-11M guidelines.

What you get

Three 1/2 inch cobalt drill bits crafted for durability, organized in a portable case. The jobber length offers a balance of reach and rigidity for a variety of drilling tasks in metal shops or DIY projects.
