Universal Tool has introduced carbide tipped through coolant drills. These are made on 8-axis CNC machines with special software designed to attain special drill point geometry. These drills have coolant feeding right up to the cutting edge with the special profile generated helical flutes. These drills are advantageous because of the following:
- they achieve holes of H9 accuracy with the finish of almost reaming,
- working at very high speed, thus increasing productivity several times,
- eliminating need of further reaming operations.
These drills provide self-centering geometry eliminating the requirement of percentage drilling or spot drilling. These drills are provided in the diameter range of 8 mm up to 60 mm in carbide-brazed design and in the range of 3 mm up to 32 mm in solid carbide design. Depending upon the application, these are also supplied in carbide lugged design length to diameter ratio [L/D ratio], to 5 to 7 times or even more machining efficiency,
