BDS HSS-VarioPLUS 12 mm Kernboor met Weldon-schacht, 55 mm snijdiepte KBL-VP012

Professional annular cutter for core drilling in steel, stainless steel, and non-ferrous metals. The BDS HSS-VarioPLUS 12 mm cutter delivers clean, burr-free holes with exceptional speed and tool life, thanks to its precision-ground HSS body and special VarioPLUS coating. Designed for magnetic core drilling machines with a 19 mm Weldon chuck, this cutter excels in structural steelwork, fabrication, and maintenance applications where accuracy and efficiency are critical.

Advantages

The HSS-VarioPLUS series combines high-speed steel toughness with an advanced coating that reduces friction and heat. Its optimized flute geometry ensures efficient chip evacuation, even in deep cuts, while the internal cooling design keeps the cutting edge cool for extended service life. The Weldon shank provides secure, vibration-free mounting, and the precision-ground cutting edges produce smooth, round holes without reaming.

Recommendations

For best results, use with a suitable magnetic drill press and apply cutting fluid or coolant. Ensure the machine's spindle speed matches the cutter diameter and material. Regularly inspect the cutter for wear and replace when cutting performance declines. Always follow safety guidelines for metal drilling.
