Fein TCT Ultra 50 12-65mm x 50mm Core Drill Bit M18 x 6 P1.5

Fein TCT Ultra 50 12-65mm x 50mm Core Drill Bit M18 x 6 P1.5

Fein TCT Ultra 50 carbide-tipped core bit with FEIN M18 thread, designed for continuous and serial drilling applications up to 50 mm deep. The durable HM construction provides long service life and high cutting performance, while the 3-flute design delivers smooth, chatter-free cutting and accurate drilling results. Ideal for economical repetitive drilling, with more holes per tool and fewer tool changes than HSS core drills. Fein specifies up to 350 holes / 7 m total service life under optimum test conditions (Ø18 mm, S235 steel, 20 mm material thickness), helping reduce drilling costs for larger quantities.

Available in a comprehensive range of diameters from 12 mm to 65 mm, allowing you to select the correct core drill size for your application. Each variation features a 50 mm cutting depth and FEIN M18 x 6 P1.5 thread for compatibility with suitable FEIN magnetic core drilling machines.
