This drill bit is suitable for drilling steel, aluminum, non-ferrous metals, plastics, and wood.
The drill bit features a 118° point angle for precise cutting.
HSS-R stands for High-Speed Steel, Roll-forged. It indicates the material and manufacturing process of the drill bit.
Clean the drill bits after each use, store them in a dry place, and apply a light coat of oil to prevent rust. Use a cutting fluid when drilling metal to reduce heat and friction.
These drill bits are manufactured to DIN338 standards.
A cooling agent reduces friction and heat, which helps to preserve the bit's sharpness and extend its lifespan.
While these bits are suitable for various materials and applications, their suitability for heavy-duty industrial applications depends on the specific requirements of the job. Consider the material thickness and drilling frequency.
Check the sharpness of the bit and replace it if needed. Ensure the correct speed and pressure are being applied.
Reduce the feed rate and ensure the drill bit is perpendicular to the work surface. Use a cooling agent when drilling metal.
Start with a pilot hole or use a center punch to create a starting point. Apply even pressure and maintain a straight drilling angle. Check the 118° point angle.
