BDS HSS standardi 26 mm porakruunu Weldon-varrella, 30 mm leikkaussyvyys KBK-026

On a busy steel construction site, a fabricator mounts this BDS annular cutter into a magnetic core drilling machine. The 26 mm HSS cutter bites into a steel I-beam, ejecting a clean core after a 30 mm deep hole. It is a go-to tool for creating large-diameter holes in structural steel, plates, and pipes without the need for pre-drilling or step drilling.

Why choose it

The BDS Standard annular cutter delivers fast, accurate holes in steel and other metals. Its HSS construction provides a good balance of toughness and wear resistance, while the Weldon shank ensures a secure, wobble-free connection to compatible magnetic drills. The 30 mm cutting depth covers common plate and beam thicknesses, and the integrated core ejection spring speeds up slug removal for continuous work.

Ideal use cases

• Drilling holes for bolts, anchors, and conduits in structural steel
• Creating large-diameter holes in plates, pipes, and profiles
• Metal fabrication, construction, and maintenance tasks
• Use with magnetic core drilling machines in workshop or on-site

Good to know

This cutter is suitable for steel, stainless steel, cast iron, and non-ferrous metals. For best results, use appropriate cutting fluid and follow the machine manufacturer's speed and feed recommendations. The cutter can be re-sharpened to extend its service life.
