BDS KBK-F 022 HSS-Co 8% jadrový vrták 22 mm hĺbka rezu 35 mm QuickIN stopka

When drilling large-diameter holes in steel, standard twist drills struggle with heat, accuracy, and effort. The BDS KBK-F 022 core drill bit solves this by cutting only the periphery of the hole, leaving a solid core. Made from HSS-Co 8% (high-speed steel with 8% cobalt), it withstands high temperatures and maintains hardness, making it ideal for tough materials like stainless steel and cast iron. With a cutting diameter of 22 mm and a cutting depth of 35 mm, it is perfect for creating precise, burr-free holes in metal sheets, profiles, and plates. The QuickIN shank ensures fast, tool-free bit changes on compatible BDS magnetic drilling machines, reducing downtime and increasing productivity.

Who is it for

This core drill bit is designed for professional metalworkers, fabricators, and maintenance technicians who need efficient, accurate hole drilling in steel, stainless steel, cast iron, and non-ferrous metals. It is especially suited for use with BDS magnetic drilling machines featuring the QuickIN arbor system, but it can also be used on stationary drills with a suitable adapter. Whether you are working on structural steel, pipelines, or machinery, this bit delivers consistent performance and long tool life.

Tips

For best results, use a suitable cutting fluid or coolant to reduce friction and heat. Ensure the workpiece is securely clamped and the drill is properly aligned. Apply steady, moderate pressure; excessive force can damage the bit. After drilling, remove the core slug from the bit. Store the bit in a dry place to prevent corrosion. Regularly inspect the cutting edges for wear and sharpen or replace as needed.
