NEO TOOLS punta per metallo HSS-Co 13,0 mm, confezione da 5 (DIN 338)

Professional workshops and demanding metalworking tasks call for drill bits that stay sharp and precise under high heat. This 5-piece set of NEO TOOLS HSS-Co twist drill bits in 13.0 mm diameter is built for exactly that. The cobalt-alloyed high-speed steel (HSS-Co with 5% cobalt) delivers superior hardness and heat resistance, allowing you to drill through tough materials like stainless steel, alloy steel, cast iron, and non-ferrous metals without premature wear. The 135° split point self-centers on contact, reducing walking and the need for center punching, while the bright, uncoated finish ensures clean chip evacuation. Conforming to DIN 338, these bits are right-hand cutting with a cylindrical shank, ready for use in corded drills, cordless drills, or drill presses.

Why choose it

Cobalt alloyed steel keeps the cutting edge harder at high temperatures, so you can work longer without resharpening. The 135° split point starts on contact and drills accurately without a pilot hole, saving time on layout. Each bit is manufactured to DIN 338 tolerances for consistent diameter and concentricity, ensuring clean, round holes in every pass.

Ideal use cases

• Fabrication shops drilling stainless steel sheet and profiles
• Maintenance crews repairing alloy steel machinery components
• Metalworking hobbyists creating precise holes in cast iron or aluminum
• Production environments requiring repeatable 13 mm holes in tough alloys

Good to know

Use cutting fluid or appropriate lubrication when drilling hard metals to extend bit life. Store bits in a dry place to prevent corrosion. The bright finish allows easy visual inspection for wear or damage. For best results, match the drill speed to the material hardness and use a drill press for maximum accuracy.
