FEIN TCT Ultra 35 carbide-tipped core bits with QuickIN holder, available in a wide range of diameters from 12 to 65 mm, with a 35 mm cutting depth. Designed for continuous and serial drilling, the conical flute provides efficient chip removal while the 3-flute design delivers smooth, chatter-free cutting and accurate drilling results. The durable HM carbide construction offers a longer service life and higher cutting speed than HSS core drills, making these core bits ideal for economical, repetitive workshop use with fewer tool changes.
FEIN specifies up to 400 holes / 8 m total service life under optimum test conditions (Ø18 mm, S235 steel, 20 mm material thickness), helping provide more holes per tool and reduce drilling costs.
