METALBOR HSS-G 77X117MM 10 STK

The ground HSS spiral drill bit for drilling through metal with maximum precision. The exposed
135-degree split self-centering point of the drill head combines active cutting with perfect

drill head  made of HSS (high-speed steel)  provides up to 40% faster drilling and up to 50%
lower clamping pressure than standard ground HSS cutting edge drill heads. This drill head is
designed for drilling holes in alloyed and non-alloyed steel  cast steel  cast iron  sintered
iron  reduced cast iron  non-ferrous metals and hard plastic. The ground HSS spiral drill bit
is manufactured according to DIN 338. The type N (notch angle) of the borehead has a 135-degree
point and a diameter tolerance of h8. It has a cylindrical shaft system (the shaft has the same
diameter as the borehead) and is intended for use in drilling stands and screwdrivers. Package
