Silverline Metric HSS-R Long Series Drill Bits 10pk - 4.0 x 119mm
Silverline 4341 HSS-R long drill bits (4.0x119mm, 10pk) for steel, aluminium & wood. DIN340 compliant with 118° point.
The Silverline Metric HSS-R Long Series Drill Bits are premium quality roll-forged drill bits made from 4341 high-speed steel, providing exceptional durability and performance. Manufactured to DIN340 standards with a precise 118° point angle, these bits are designed for general-purpose drilling in various materials including steel, aluminium, non-ferrous metals, plastics, and wood.
For optimal results in metal drilling, we recommend using a cooling agent and drilling at slow speeds to extend the lifespan of the bits and ensure clean cuts. The long series design (119mm) offers increased reach, making them ideal for deeper drilling applications.
