Description
Excellent cobalt drill bit made of M35 HSS and 5% cobalt for extra strength. The low loss of sharpness and wear allows these drill bits to last a long time. The 135° milled double-edged heads provide additional grip. The tips are sanded and finished with amber colour. Each cobalt drill in our range is manufactured to DIN340 extra long standard. The use of cutting drill bits is suitable for better performance. We recommend the drill or cooling oil.
