Twist drill bit made of high speed steel. Right hand cutting twist drill bit. Rolled spiral flute with ground point, vapour-plated.
Advantage: Improved centring when starting to drill and a reduction in the required drill forward pressure.
For drilling in alloyed and unalloyed steel upto a tensile strength of 900N/mm2, non-ferrous metals, cast iron and hard plastics.
Bosch HSS-R metal drill bits, manufactured to DIN 338, gain high elasticity from a low-heat shaping manufacturing process. This reduces the risk of breakage, especially when drilling with diameters smaller than 6 mm. The flute has an oxide coating which enables quick swarf removal. The drill bit has a particularly tough core thickness and distinct hardness within its area of application, thus ensuring long life
