Conjunto de 25 brocas de metal HSS-Co cobalto NEO TOOLS, 1,0–13,0 mm, totalmente retificadas, ângulo de ponta 135°, DIN 338, caixa metálica

In a busy metalworking shop, a technician reaches for a drill bit set that can handle stainless steel, cast iron, and non-ferrous metals without dulling or wandering. This NEO TOOLS 25-piece set delivers exactly that—precision-ground HSS-Co bits with 5% cobalt for superior heat resistance and long life. From 1.0 mm to 13.0 mm in 0.5 mm steps, every common diameter is at hand, stored in a sturdy metal case for organization and protection.

Key specifications

• Material: HSS-Co (High-Speed Steel with 5% Cobalt)
• Set quantity: 25 pieces
• Diameter range: 1.0 mm – 13.0 mm (0.5 mm increments)
• Point angle: 135° split point for self-centering and reduced walking
• Shank type: Cylindrical, fully ground per DIN 338
• Storage: Durable metal case

Why choose it

The cobalt alloy withstands high drilling temperatures, making these bits ideal for tough materials like stainless steel, acid-resistant steel, and heat-resistant steel. The 135° split point cuts faster and requires less pressure, while the fully ground flutes ensure smooth chip evacuation and accurate holes. With 25 sizes in one case, you are ready for almost any metal drilling task without searching for individual bits.

Ideal use cases

• Professional workshops drilling stainless or acid-resistant steel
• Maintenance and repair of machinery and metal structures
• DIY projects involving cast iron, non-ferrous metals, or structural steel
• Precision drilling where hole accuracy and bit longevity matter

Good to know

Each bit is manufactured to DIN 338 standards, ensuring consistent dimensions and compatibility with standard drill chucks. The metal case keeps the set organized and protected, making it easy to transport between job sites. For best results, use cutting fluid and appropriate speeds for the material being drilled.
