Bosch HSS-R metal drill bits, manufactured to DINFor drilling in alloyed and unalloyed steel up to a tensile strength of 900N/mm Squared, non-ferrous metals, cast iron and hard plastics. 338, gain high elasticity from a low-heat shaping manufacturing process.
This reduces the risk of breakage, especially when drilling with diameters smaller than 6mm.
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 for long life.
