FEIN 63134999063 kroonboor-set, 6-delig, 12-22 mm, HSS-Nova, Weldon-schacht, 30 mm snijdiepte

Drilling large-diameter holes in steel often means fighting with twist drills that wander, overheat, and leave rough, oversized bores. The FEIN 63134999063 annular cutter set eliminates that frustration by removing only a ring of material, not the entire core. This six-piece kit covers the most common structural steel diameters from 12 mm to 22 mm, giving you clean, accurate holes with far less effort and tool wear.

Who is it for

This set is built for metalworking professionals and serious fabricators who use magnetic core drilling machines. If you regularly drill beams, plates, or pipe in steel, stainless steel, or non-ferrous metals, these cutters will save you time and extend the life of your machine. The included storage case keeps everything organized and protected on the job site or in the workshop.

Tips

Use cutting fluid or paste to prolong cutter life and improve hole quality. Ensure the magnetic drill is securely attached and the cutter is properly seated before starting. Apply steady, even pressure—let the tool do the work. After use, clean the cutters and store them in the provided case to prevent damage.
