Versatile 4341 HSS-R long series drill bits (6.5x148mm) for steel, aluminium, wood & plastics. DIN340 certified.
The Silverline Metric HSS-R Long Series Drill Bits are crafted from 4341 high-speed steel, ensuring durability and precise cutting performance. These professional-grade bits are roll-forged and manufactured to DIN340 standards, featuring a 118° point angle for efficient material penetration.
These general-purpose 'jobber' drill bits are versatile enough to handle various materials including steel, aluminium, non-ferrous metals, plastics, and wood. For optimal results when working with metals, we recommend using a cooling agent and drilling at slower speeds to prolong bit life and enhance performance.
Each pack contains 5 drill bits, each measuring 6.5mm in diameter and 148mm in length, making them ideal for deeper drilling applications where standard-length bits may not suffice.
