Machined from hard-wearing Swiss steel, Festool ZOBO bits set a new standard for precision hole cutting. Interchangeable pinpoint and pilot bits enable rapid, precise drilling at angles up to 70deg, while highly efficient chip ejection prevents overheating, keeping cutters sharper longer. ZOBO bits clear their own path, effortlessly speeding through dense material, saving time and wasted steps. Quick-change shanks are best suited for use with Festool Centrotec System, but ensure secure gripping in any keyless chuck. Includes: Bits: 15mm, 20mm, 25mm, 30mm, 35mm; plus pinpoint and pilot inserts.
