Wiertło (świder) Bosch METALBOR HSS-TIN 135GR 2-8MM 6STK ROBUST

The HSS spiral drill bit, titanium, provides maximum lifespan when drilling holes in metal. If an appropriate cooling system is used, the drill head has the lowest possible friction and minimal wear thanks to its titanium nitride coating. The high surface quality of this ground spiral drill bit, made of HSS (high-speed steel), extends its lifespan. It is suitable for use on alloyed and unalloyed steel, reduced cast iron, sintered iron, new silver, copper, bronze and hard plastic such as perspex. The HSS spiral hammer drill in titanium is manufactured according to DIN 338. The drill head is of type N (notch angle) with a 135-degree point and a diameter tolerance of h8. Active cutting and perfect centering without displacement are achieved thanks to the two-part tip. Do not use with aluminum and always use coolant. This hammer drill has a cylindrical shaft system (the shaft has the same diameter as the hammer drill) and is intended for use in drilling stands and screwdrivers.
