The flat-bottomed drilling range has been added to the Rainford Precision series to provide a drilling solution for angular, radial and other irregular surfaces.
The new range is available in diameters from 2mm to 12mm with plus sizes offered for drilling pre-thread holes for M4, M6, M8, M10 and M12 threads. Like all Union tools, the new additions are manufactured from a high-quality solid carbide composition with a precision ground shank and the company’s latest generation coating technology that extends tool life and performance.
Added to this, the drills have a flat land and 30° helix angle that combine to provide a robust geometry design that generates excellent chip removal and stability. This results in highly-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.
The UTDF drills have also been developed with an innovative web-thinning design and double margin that enhance performance with regard to swarf evacuation, edge sharpness and stability. Depending upon selected diameter sizes, the drills have an overall length from 50mm to 100mm and flute lengths from 8mm to 48mm.
