Available in diameters from 2 to 12 mm, with plus sizes offered for drilling pre-thread holes for M4, M6, M8, M10 and M12 threads, the UTDF drills are manufactured from a high quality solid carbide composition with a precision ground shank and Union Tool’s latest generation coating technology that extends tool life and performance.
Added to this, the new UTDF drills have a flat-land and 30° helix angle that combine to provide a robust geometry design that generates exceptional chip removal and stability. This results in efficient drilling cycles and prolonged tool life on a range of materials that includes alloyed, structural, pre-hardened and carbon steels, as well as cast iron and aluminium alloys.
Another feature of the drill range is an innovative web-thinning design and double margin that both enhance performance, as regards swarf evacuation, edge sharpness and stability. Depending on selected diameter sizes, the UTDF drills have an overall length from 50 to 100 mm and flute lengths from 8 to 48 mm.
