HSS Drill Bit (Metric):19mm - DIN 338

This high-speed steel drill bit is a precision cutting tool manufactured to the DIN 338 standard, featuring a nominal diameter of 19mm. Constructed from high-speed steel, it is engineered to maintain hardness and structural integrity under the elevated temperatures generated during drilling operations. This specific metric-sized bit is selected by manufacturers and machinists for creating precise 19mm holes in ferrous and non-ferrous metals where standard twist bits may struggle with wear resistance. The robust construction ensures consistent hole geometry and extended tool life compared to softer carbon steel alternatives. When selecting this product, verify that the 19mm diameter aligns with your specific fastener sizing requirements and that the DIN 338 designation meets the dimensional tolerance needs of your assembly process.
