BDS HSS-VarioPLUS 25 mm jadrový vrták s Weldon stopkou, 30 mm hĺbka rezu KBK-VP025

Core drilling in steel, stainless steel, cast iron, and non-ferrous metals demands a cutter that stays sharp, cuts cleanly, and withstands the rigors of magnetic drilling machines. The BDS HSS-VarioPLUS 25 mm annular cutter answers that challenge with high-speed steel construction and an optimized geometry for universal metalworking. Its Weldon shank ensures a secure fit in standard magnetic drill chucks, while the 30 mm cutting depth handles most plate and profile work without pilot holes. From maintenance crews to fabricators, this cutter delivers consistent holes with minimal burrs and long service life.

Who is it for

Professional metalworkers, steel erectors, pipe fitters, and maintenance technicians who rely on magnetic drilling machines for on-site or workshop fabrication. It suits anyone needing precise, large-diameter holes in structural steel, stainless steel, cast iron, or non-ferrous metals without pre-drilling.

Main features

• High-speed steel (HSS) body with bright finish for durability and corrosion resistance.
• 25 mm cutting diameter and 30 mm cutting depth for common plate and profile thicknesses.
• Weldon shank (19 mm / 3/4 inch) for secure clamping in magnetic drill chucks.
• Two cutting edges with optimized geometry for universal use on steel, stainless, cast iron, and non-ferrous metals.
• External coolant system compatibility for extended tool life and better chip evacuation.
• Made in Germany to exacting quality standards.

Tips

Always use cutting fluid or coolant when drilling steel or stainless steel to reduce heat and prolong cutter life. Ensure the Weldon shank is fully seated and the locking screws are tight before starting. For best results on thick material, apply steady pressure and allow the cutter to do the work—do not force it. After use, clean the cutter and store in a dry place to prevent corrosion.
