Broca de coroa BDS KBK-F 015 HSS-Co 8% diâmetro de corte 15 mm, profundidade de corte 35 mm, haste QuickIN

Drilling large-diameter holes in steel often means struggling with twist drills that wander, overheat, and demand excessive power. The BDS KBK-F 015 annular cutter eliminates these frustrations by cutting only the periphery of the hole, leaving a solid core that ejects automatically. This efficient approach reduces cutting forces, extends tool life, and produces clean, burr-free holes in a fraction of the time.

Who is it for

This cutter is built for metalworking professionals—fabricators, maintenance crews, and machine operators—who need fast, accurate holes in structural steel, stainless steel, cast iron, and non-ferrous metals. It is ideal for use with BDS magnetic drilling machines equipped with the QuickIN system, but it also fits any compatible arbor with the same shank.

Main features

• High-speed steel with 8% cobalt (HSS-Co 8%) for superior heat resistance and wear life, even in tough materials up to 900 N/mm² tensile strength.
• 15 mm cutting diameter and 35 mm cutting depth for common through-hole and blind-hole applications.
• QuickIN shank enables tool-free, one-handed insertion and removal, dramatically reducing changeover time.
• Ground flutes and bright finish ensure smooth chip evacuation and reduced friction.
• Automatic core ejection via spring-loaded pilot pin—no prying or hammering required.
• Compatible with external or internal coolant supply for extended tool life and better surface finish.

Tips

Always use cutting oil or coolant suitable for the material being drilled. For stainless steel, reduce speed and increase feed pressure to prevent work hardening. Ensure the QuickIN arbor is clean and undamaged before mounting. Store cutters in a dry place to prevent corrosion.
